This episode examines how heat stress affects water intake in dairy cows—and why farms must prepare their watering systems for increasingly hot weather.A review of studies from 1985–2024 found that Holstein cows producing roughly 65–70 pounds of milk averaged about 24 gallons of water per day under thermoneutral conditions. During heat stress, intake increased by approximately 10 liters, or 2–3 gallons, per cow per day. Each one-unit increase in the temperature-humidity index was associated with another 1.5 liters of water intake. Although heat-stressed cows produce less milk, they drink more because the additional water supports evaporative cooling and body-temperature regulation.Data from the University of Minnesota's dairy herd revealed a more complicated picture. smaXtec sensors showed that cows averaged around 23 gallons per day, but estimated intake declined during summer. Possible reasons include warmer drinking water, pasture water access, competition at waterers, and changes in drinking behavior. Cows generally drank only four or five times per day, consuming roughly 14–20 liters at each visit. Peak drinking also shifted from midafternoon in winter to around 7 p.m. in summer, often after milking.These patterns highlight the importance of examining when cows drink—not just daily totals. Farms should ensure adequate water flow, tank capacity, access, and cool water during peak-use periods. Sensor readings are most valuable when compared with each cow's normal behavior and interpreted alongside weather, milk production, rumination, health events, and management changes.The central message is that water intake can be a useful indicator of heat stress, but unexpected changes should prompt investigation rather than an automatic conclusion. As extreme heat becomes more common, dairy water systems must be designed for peak demand rather than historical averages.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad shares preliminary results from a University of Minnesota study examining feed intake, methane emissions, and feeding behavior in Holstein and crossbred dairy heifers. Using precision feeders, methane-monitoring equipment, and activity sensors, the research team compared Holsteins with ProCROSS and GrazeCross heifers.The early findings show that methane production generally increased with feed intake. Smaller GrazeCross heifers consumed less feed and produced less methane and carbon dioxide, while ProCROSS heifers had the highest feed intake. However, methane produced per unit of dry matter intake did not differ significantly among the breed groups.Brad also discusses how often heifers visited the feed bunk, how much time they spent eating, and what sensor data revealed about rumination and activity. These preliminary results highlight how body size, breed, and feeding behavior may influence heifer management and environmental efficiency.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad takes a closer look at heat stress in dairy calves and cows. This episode highlights several recent studies on how temperature-humidity index affects calf behavior, lying time, respiration rates, shade use, and growth performance.Brad discusses research from the University of Guelph, The Ohio State University, and Mississippi State showing that heat-stressed calves spend less time lying down, stand more often, breathe harder, and may gain less weight when shade is not provided. He also reviews a Texas A&M study using precision livestock technology to monitor drinking behavior, rumen temperature, and heat stress responses in robotic milking herds.The big takeaway: heat stress in calves deserves more attention. Simple strategies like shade cloth, better ventilation, and more thoughtful housing design may help improve calf comfort, growth, and long-term performance.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory

Welcome to Uptime Spotlight, shining light on wind energy’s brightest innovators. This is the progress powering tomorrow Allen Hall: Nicholas, welcome back to the podcast.  Nicholas Gaudern: Thanks, Allen. Great to be back.  Allen Hall: So there’s a lot going on at Power Curve, and I saw some news online about Power Curve in India.  Nicholas Gaudern: Yes.  Allen Hall: Which is a new development.  Nicholas Gaudern: Yeah, so we’ve been working in India for, for some years now, and we have, uh, more than 100 turbines out there with our equipment on, primarily vortex generators so far. And what we’re seeing in India is some of the highest AEP gains we’ve ever recorded with our vortex generators And I think a lot of this is being driven by the fact that in certain parts of India, there’s some very unique, uh, environmental conditions, climatic conditions, and there’s parts of the year, like the dry season up in [00:01:00] the north of India, where you’re getting this very sticky dirt accumulating on the blades. And it’s really quite dramatic when you see the photographs, but that means that the blades are actually starting to, to stall, have flow separation on them.  Allen Hall: I’ve seen pictures of that. Yeah. I was really shocked at the time, uh, ’cause I didn’t know it was just kind of a black, gooey- Yeah … kind of tar-like substance- Yeah, yeah on the blades, and, uh, it, it was only on there a limited time. As soon as the monsoons come through and the rains hit, it would wash, eventually wash it off. Yes. But while it’s there, you could see the airflow over the blade surfaces. You, you could definitely see separation happening really early on those blades. Dramatic.  Nicholas Gaudern: Yeah, absolutely, and I think the, um… Like you say, it’s not all year. No. But it doesn’t have to be all year to have a huge impact on, on how many, you know, megawatt hours you’re getting out the other end. So there’s a few months of the year where this problem is particularly severe, maybe sort of December through to February, something like that. And what we’re finding is that when you see, uh, the power curves for these [00:02:00] turbines, some of them aren’t even hitting rated power. They’re not able to hit rated power because there’s so much flow separation on the blades.  Allen Hall: Wow.  Nicholas Gaudern: And that, I mean, just imagine that. You’ve got a two megawatt turbine, for example. Maybe it doesn’t cast- get past 1.5 megawatts for this, uh, time of the year. I mean, that’s crazy.  Allen Hall: Does the turbine try to adjust itself when that happens? Because the pictures I s- have seen indicates, like, the turbine is pitching the blades to, ’cause it knows- It can- …  Nicholas Gaudern: what the wind  Allen Hall: speed is- I mean, yeah … and it knows what it should be putting out, and it’s not putting that out. Nicholas Gaudern: It’s very turbine specific, kind of controller logic specific, but what we see is even the turbines that try to do something, they’re very limited in how much pitch authority they have from the controller. They might be able to just do a little bit, a degree. Okay. Two degrees. You know, very, very small pitch adjustments. And when you have this kind of dirt on the leading edges, a degree of pitch ain’t gonna save you really. Um- N-  Allen Hall: no. And I think that’s what we’re seeing. And it’s not gonna get that power back. No, no.  Nicholas Gaudern: No.  Allen Hall: But does it add extra load onto the blade structurally over [00:03:00] time when you do that?  Nicholas Gaudern: In terms of the pitching, or-  Allen Hall: Yeah, in terms of the pitching, where you’re trying to be more aggressive on the angle of attack to get the power out of the turbine. Potentially. And the winds are still pretty strong, you just, the blades are inefficient.  Nicholas Gaudern: I think it’s one of those things where there’s, there’s so many interconnected items with the dirt and the controller and the structure. It’s actually pretty difficult, I think, to say with confidence how much life impact you would have from that. But what I would say is the more that you might end up trying to pitch, if that’s what’s going on on some machines, that obviously puts wear on the pitch bearings themselves. But yeah, I think at the moment we’re kind of at the beginning of really trying to understand how some of these turbines do deal with this phenomenon. But what we’re trying to do is get to a point where the turbine doesn’t really have to deal with it. Because if you fix the problem at the source, which is stop the flow separating, then the controller doesn’t really have to, to worry. It doesn’t have to try to, to fix it itself.  Allen Hall: Yeah. That makes a lot more sense. Just the number of images I’ve seen over the last couple years from India-  Nicholas Gaudern: [00:04:00] Yep …  Allen Hall: you realize how difficult it is to operate a wind turbine there.  Nicholas Gaudern: So even when we, um, have this issue for a few months that we’re resolving with the VGs, we can still be seeing over the whole year more than 5% increases in annual energy production. Because those months are really important. Um ‘ Allen Hall: Cause that’s when they need the  Nicholas Gaudern: power. Yeah, yeah, yeah. Exactly. For sure. And this is primarily coming from the vortex generators towards the tips of the blades. So that’s where you’re having this, uh, heavy contamination issue, and that’s where all the power would be produced. So kind of the outer third of a blade is 50, maybe 60% of the power production of a turbine, maybe closer to 50. So that means that if you have a problem out there, it’s, it’s a big problem in terms of your annual energy production. So-  Allen Hall: Right …  Nicholas Gaudern: the VGs are, what they’re doing is they are, they’re injecting energy back into the flow. Allen Hall: Redirecting the flow, in a  Nicholas Gaudern: sense. So, so basically you have all this contamination on the leading edge. It’s generating more turbulence. The flow isn’t able to retain, uh, remain attached [00:05:00] across the entire chord length. So the VGs are putting energy back into the flow and allowing it to remain attached all the way to, uh, to the trailing edge. Allen Hall: So even with the blades are dirty-  Nicholas Gaudern: Yes …  Allen Hall: you get that power out- Exactly … put, that you really desire or-  Nicholas Gaudern: Yeah …  Allen Hall: are paying for. Yeah. You, you paid a lot of money for that turbine- Yeah, exactly … you need to get the power out of it.  Nicholas Gaudern: Yeah.  Allen Hall: And-  Nicholas Gaudern: So of course, you know, that suggests that if you had a, a super clean blade, you went and pressure washed it, uh, you would get, uh, an increase in power as well, and that’s true. You, you- That’s true … you will do. But that’s a one-time thing. Um, so- And  Allen Hall: it’s expensive to do- Yeah … and time-consuming.  Nicholas Gaudern: Exactly. Maybe a few days later, the dirt’s back. So- Sure … you know, it’s not really a sustainable thing for you to be going out washing these blades the whole time. And washing the blades may not be great for the surface of the blade either. So, you know, a VG is just sat there the whole time. It doesn’t matter if it’s dirt, bugs, erosion, frost, it’ll recover those losses that, that you’re seeing.  Allen Hall: Do the VG installations in a situation like that, [00:06:00] the actual location differ because of the contaminants that are present and the kind of, uh, leading edge effects that you’re seeing? Do you design it for that environment? Or- Yeah … is every- Oh, you do. So- Yeah, we  Nicholas Gaudern: do. I mean, typ- typically our, our VG arrays are turbine model specific. But in India, we’re finding we’re actually having to be more site specific as well. Oh,  Allen Hall: wow.  Nicholas Gaudern: Because some of this contamination is so severe, we’ve seen that we need to design the VG layout a little bit differently to make sure that we’re giving enough, uh, energy recovery potential when you have these really severe, uh, situations. Allen Hall: Are you using the AeroVista tool to do that? How do you, how do you quantify the contamination that’s happened on the leading edge at a particular moment or roughly on scale a- and then try to model that? That just seems like a difficult computation.  Nicholas Gaudern: It is. And, um, you know, we’re, we’re getting better all the time. AeroVista is definitely part of that. So AeroVista’s primary function really is to look at, um- [00:07:00] AEP losses due to structural damages, things like erosion. But actually, erosion behaves very similar to dirt when it comes to, like- It, right … aerodynamic behavior. Yeah. So we can actually use kind of the AeroVista engine to help us understand what is the loss from different levels of contamination. So we can add contamination levels into AeroVista, as well as, uh, erosion. And we can start to look at, well, what happens if the blade looks like this? What if it looks like this? And then this gets combined with our computational fluid dynamics, our CFD models that we’re running, three-dimensional, two-dimensional. We sometimes do some aeroelastic modeling as well. So we basically have a big toolbox, and like with any engineering problem, it’s about picking the best tool for the job. So we just go in, and we have all these great tools, and we, we put them together in a workflow that allows us to design the, the best solution for each site that we look at. Allen Hall: And it’s not India-specific in terms of leading-edge contamination. No. I’ve seen pictures from the US, Brazil, um, [00:08:00] Australia, a number of places where there’s just bugs. Yeah. Right? Those, especially in places where there’s large bugs- Yes. … you kind of get this splatter effect going on. Yeah. And you can have a really contaminated blade surface. In the US, in the middle of the US, you’ll have grasshopper season, and-  Nicholas Gaudern: Yeah, absolutely …  Allen Hall: tho- those grasshoppers are big, and they splatter. And they leave a disaster. We’ve seen  Nicholas Gaudern: that in, uh, in the Midwest, for sure. Oh, yeah. Some really, really severe contamination from bugs.  Allen Hall: And you, you don’t think about, as an engineer or a site supervisor, that- All right. This sort of, uh, grasshopper season that happens is affecting my AEP, but 100% it is. And that stuff is gooey, so if you ever drive through the Midwest in the summertime- … you run through, uh, any kind of insect swarm and try to get it off your vehicle. Yeah. It takes some scrubbing.  Nicholas Gaudern: Yeah. It re- it really does. And imagine when you’ve gotta go up there for, like, 100-meter diameter rotor.  Allen Hall: Right. ‘ Nicholas Gaudern: Cause that’s quite a challenge. So I think, yeah, they have all these challenges, uh, in terms of environmental conditions, and a lot of people consider aerodynamic [00:09:00] behavior blades quite binary. Either the blade is clean or the blade is dir- Or it’s dirty or it’s dirty. Right. But it’s this entire spectrum. It’s everything in between, and I think that is kind of a little bit of a different way of thinking about the problem. And then it makes the argument around why to put VGs there kind of, uh, easy to, to answer, because the blade is never really truly clean. Allen Hall: No. I… Unless it’s right after a rainstorm- Yeah … I rarely see clean blades. Okay, so the … If VGs are going on, are you using the DragonScale VGs to solve some of the India problems, some of the contamination problems?  Nicholas Gaudern: So DragonScale’s not in India yet. That’s something that we’re looking at. So we, um, we got all the tooling finished for DragonScale some months ago now, and we’re shipping DragonScale kits. Uh- Oh, wow. Okay … not, not to India yet, but they are out in, in the field, and we’re gonna be having some more out just in the next couple of weeks, actually, which is quite exciting. We’re doing our first project, um, in Canada.  Allen Hall: Oh.  Nicholas Gaudern: So we’re starting to kinda come across the, the pond with the VGs now, [00:10:00] with the DragonScale VGs. Allen Hall: So the DragonScales, uh, uh, uh, thank you for bringing a, a sample here today, but the, the DragonScales are really interesting in terms of just the way the airfoil shapes are and how they’re s- kinda stacked and layered- Yeah … and there’s different depths to them, heights to them, to get the flow back where you want it to. Yeah. And it, I guess it depends on where you are on the blade. If you’re near the root, they’re gonna look something like this. Exactly. Yep. If you’re getting near the tip, they’re  Nicholas Gaudern: much  Allen Hall: smaller- Yeah, we have some smaller ones. Yep … scale, scale of this. So- This then, the Dragon Scales do require a little bit of computational knowledge of what’s going on- Yep with the blade. And as you say, they- You just can’t willy-nilly stick  Nicholas Gaudern: them on … they’re, they’re quite different. You know, they’re quite different from a standard triangle of VG.  Allen Hall: Right.  Nicholas Gaudern: And, you know, there’s lots of ways that you can create a vortex aerodynamically. And triangles- Sure … create a vortex, sure, but they, they really create one through a process of separation. Yeah. You have a flow hitting this, this plate that’s angled to the flow. It’s rolling over the top, and it’s tripping into a, into a vortex. But that’s quite a draggy way [00:11:00] of- It is … creating a vortex. Yes. Um, so VGs work. We’ve seen that. You know, we have more than 2,000 turbines now with VGs, so we, we know they work. Yeah. But Dragon Scale, the whole idea is not that we … This is still a VG. It’s still creating a vortex. Sure. But it’s doing it in a much more efficient manner, so we get the same lift recovery benefits, lift boosting benefits, but at a much lower drag. So we have a better drag ratio. ‘Cause it’s the drag, right? Allen Hall: It’s the drag. The little triangular-  Nicholas Gaudern: Yeah …  Allen Hall: vortex generators are draggy.  Nicholas Gaudern: So anything you stick on a blade, it, it has a drag. It has a parasitic drag component. Um, they have a huge benefit that outweighs that. That’s why we put them on.  Allen Hall: Yeah.  Nicholas Gaudern: But of course, you can always do better. And I think here we really try to take inspiration from, from lots of the aerodynamic developments we’ve seen over the past decades in aviation and motorsport and, and these other disciplines. Allen Hall: Right. I always say these look like a Formula One  Nicholas Gaudern: add-on. Yeah, yeah. Exactly. A bigger blade. Or maybe some front slats of a aircraft or some, uh, gas turbine cascading elements- Oh, sure.  Allen Hall: Yeah …  Nicholas Gaudern: these  Allen Hall: kind of things. Yeah.  Nicholas Gaudern: Yeah.  Allen Hall: Gas turbine people would easily recognize this. Yeah, [00:12:00] I  Nicholas Gaudern: think so.  Allen Hall: Uh, so the, the Dragon Scales then in terms of, uh, the location of them on the blade, would it differ than the triangular VGs in terms of generic location? A, a  Nicholas Gaudern: little bit, but broadly it’s the same because- Okay … you know, ultimately the fundamental physics of what we’re trying to do hasn’t changed.  Allen Hall: Sure.  Nicholas Gaudern: Um, so we’re kind of, we’re addressing the same areas of the blade. But the Dragon Scale gives us a bit more flexibility. We can have these three fin versions that create a very powerful vortex, so we find those down in the root, ’cause that’s where we just want as much lift as possible. Right.  Allen Hall: Yeah. Right.  Nicholas Gaudern: Uh, but out at the tip we actually have a two fin variant. Oh. Because there we’re, we’re more focused on L over D. We wanna maximize our lift-to-drag ratio.  Allen Hall: Sure.  Nicholas Gaudern: Because that’s where the drag really hurts you, out towards the tip.  Allen Hall: So are they in a strip form then? Yes. Very similar to the triangular VGs? Nicholas Gaudern: Yeah, exactly. So the, the smaller ones on the strip, just because they’re only, like, five millimeters high.  Allen Hall: Yeah. They wanna  Nicholas Gaudern: see more- So otherwise it’s, it’s kind of watchmaking if they’re individual- … little pieces, uh, going down on the blade. O-  Allen Hall: okay. Yeah. Well, that’s fascinating. All right. Uh, I wanna talk about [00:13:00] Silent Edge before I, I lose you today. The Silent Edge product has been out in the field- Mm-hmm … and there has been some noise testing done, which I always think is very interesting because I’ve- Yeah … I’ve watched videos from, mostly from DTU, explaining how they do this, where they got the microphones around. And like- Yes … wow, that’s a really complicated test to go pull off. But you just got through a series of these-  Nicholas Gaudern: We did …  Allen Hall: noise tests with Silent Edge. And you have the results back.  Nicholas Gaudern: We do, yeah. I mean, it was a really exciting, um, test program, and we were partnered together with, uh, Statkraft, who very kindly lent us a few of their wind turbines up in Sweden. Uh, and we are working with the Danish Technical University, DTU Wind, to help with the measurements and actually figure out what’s going out on the turbine. So this was a project that we were, um, able to secure some funding from, from the Danish, uh, EUDP. So that’s the Energi [00:14:00] Teknologisk Udviklings- og Demonstrationsprogram.  Allen Hall: Right.  Nicholas Gaudern: Yeah. Nothing to do with the EU. It’s a very, it’s a Danish thing. Danish, yeah. But there is EU in the name. Right. Um, so they supported this project with Statkraft and DTU, and what we found is that when we put a Silent Edge on a, uh, it was like a two, two and a half megawatt machine, it had no serrations before. Okay.  Allen Hall: So we measured- So just a out of the factory blade.  Nicholas Gaudern: Yeah, exactly, and it was in good condition. It had had a recent repair campaign, so the blade was in, in good shape. And then what we did, uh, or what DTU did, is they went out and they measured the noise of this turbine according to the IEC standard. So there’s an IEC standard on how you should measure noise and what microphones to use and how to post-process it, and then we installed the Silent Edge serrations. And firstly, before we’d even done any measurements, we had people out at site, and they, they live out there. They’re the technicians. They see these- Okay turbines every day, and they went, “What, what have you, what have you done to, to this turbine?” Because it sounded so different. It sounded much [00:15:00]quieter. The, the quality of the sound was very different, and they just, they just stepped out the car and went, “Wow.” “This is, this is really impressive.” Um-  Allen Hall: So what, give me a description of what the sound is. I know generally, when you come with a standard blade, it has that kind of shoop, shoop-  Nicholas Gaudern: Yeah, exactly … shoop. It basically just really brings down that perceived loudness of the sound, so it’s just a m- it’s a much quieter sound, and we’re also taking out quite a lot of low frequency component.  Allen Hall: Okay.  Nicholas Gaudern: That’s what- These serrations are really targeting the lower frequencies, so kind of around the kilohertz and, and under. Allen Hall: Mm.  Nicholas Gaudern: That’s where these things are really starting to bring down the, um, the decibels.  Allen Hall: This- So, okay. So Silent Edge is, uh, sort of a unique design, or is a unique design i- in terms of the- What you see on the typical trailing edge, which are a bunch of triangles or dino tails, right? Yes, dino tails. Yes,  Nicholas Gaudern: yeah. Allen Hall: Dino tails is, was the generic term for years, and they looked like dino tails, so, so it’s a good description- Yeah … of them. But these more, look more like a cathedral in  Nicholas Gaudern: a sense. Yeah, these, these are quite different though. So we have kind of this iron-shaped, uh, tooth fundamentally, [00:16:00] but we have three different tooth sizes, uh, and they’re asymmetric. Allen Hall: Mm.  Nicholas Gaudern: And I would love to come here and tell you that we know exactly how this works. Um, but I can’t unfortunately, and, and that’s just how it is sometimes with engineering. We cannot simulate this in the detail required to really understand exactly why each geometric feature does what it does. And if someone claims they can do that, then, then I may be a bit suspicious. Or, or I’d really like to talk to them, one of the two. Um, but that means that to develop this kind of product successfully, you have to go to the wind tunnel. Okay. Because the simulation is so demanding. So we go to the wind tunnel. We spent a lot of time in the Paul Ricard wind tunnel at DTU, so we can measure aerodynamics and acoustics at the same time And we went with lots of components and 3D prints, and we iterated through design paths, and we came up with this, I think it’s a really wonderful shape we’ve ended up with. And it was proven out in the field because the final result was we reduced the overall sound [00:17:00] pressure level of the turbine by five decibels. And that is- Whoa … that is huge.  Allen Hall: That’s a lot.  Nicholas Gaudern: So in terms of, like, perceived, uh, loudness of the sound, that’s like a 30% reduction. So this is why the, the technicians who st- stepped out the car heard such a difference, because it’s a massive reduction in, in what the turbine produces. So  Allen Hall: you’re lowering the decibels coming off the, the trailing edge. Yeah. But also moving around the frequencies so it’s a little less-  Nicholas Gaudern: Yeah, so a lot of that- … uh- That… So the- …  Allen Hall: noticeable  Nicholas Gaudern: also … the five decibels, that’s, that’s this OASP, or we call it overall sound pressure level. This is an integration of all of the reductions we see across the frequency spectrum. Oh,  Allen Hall: okay.  Nicholas Gaudern: All right. So we’re getting more reduction at lower frequencies. Right. Good. There’s also some high frequencies. But the lower frequencies matter more. So what we do when we’re doing acoustic measurement is we A-weight, we, we weight the, the noise because it relates to how the human ear perceives sound. Allen Hall: Sure.  Nicholas Gaudern: So it matters more to you, the one [00:18:00] kilohertz frequency than the 20 kilz- kilohertz frequency.  Allen Hall: Yeah. Can’t hear  Nicholas Gaudern: 20 kilohertz. E- exactly. So that’s right at the upper end. So we weight the results, and this is part of the ICE standard, to understand how the human ear perceives the sound.  Allen Hall: Oh, wow. Okay.  Nicholas Gaudern: Um, and this is where we get our, our five decibels  Allen Hall: from. So this, this was really an iterative process then- Yeah … in the DT laboratory. Yeah. Ooh, wow. I didn’t realize that. Mm-mm. I, I figured you had gotten relatively close by computational methods and then- We- … honed it a little bit …  Nicholas Gaudern: we, we come sort of computate… We do a lot of computation around the angle of the serrations, because the angle of the serration is really critical for, uh, lift generation and loads. Allen Hall: So when you’re speaking of angle, you’re talking about- E-  Nicholas Gaudern: exactly … this angle back here at the- You can see that angle there. Okay.  Allen Hall: Yeah,  Nicholas Gaudern: yeah. Because you don’t want to put a serration on a turbine and add 20% to the lift of the blade. Right. No. Because-  Allen Hall: That’s not- …  Nicholas Gaudern: lift means loads. Yeah.  Allen Hall: You know? Right. You’re adding load. Nicholas Gaudern: So you have to be very careful about how you design these products to make sure that you’re not gonna add extra load to the turbine. And, and on the flip side, you also don’t wanna reduce lift significantly, which then [00:19:00] there’ll be less power produced. So it’s a bit of a balancing act, and this is where the computation comes in. We do a lot of CFD on these to make sure that we’re, we’re handling the loads correctly.  Allen Hall: And how important is the material choice- Yeah … in terms of the noise quieting? Is there a little bit to it about, well, one, durability. Yeah. You, you want to put them on once and leave them forever, so there’s a lot of interactions between the air and these parts that are gonna flex and bend, and you got- I think there’s, you know- 20 years of  Nicholas Gaudern: doing  Allen Hall: that …  Nicholas Gaudern: the, you’ve, you’ve s- you’ve hit the, hit the nail on the head there. The durability is critical. Yeah. It doesn’t matter if you put these products on the blade, and they perform beautifully for six months and then fall off or, or snap or whatever.  Allen Hall: Right.  Nicholas Gaudern: So no, we, we make these products out of the same material as our VGs, and this is a material, uh, it’s an ASA, uh, plastic. And we’ve had these out in the, in the field for a long time now, so we know- It’s- … this, this is great.  Allen Hall: It’s ex- it’s kind of a flexible material.  Nicholas Gaudern: Yeah, there’s  Allen Hall: a little b- It’s stiff but flexible.  Nicholas Gaudern: Yeah, exactly. There’s a bit of give in there- Yeah … uh, which is important, but it’s very impact-resistant. Uh, it doesn’t really suffer much in terms of [00:20:00] UV aging, which is obviously critical- Oh, wow. Yeah … when you’re, when you’re- Very critical, yes … out in the field. Yes. So yeah, we’re, um, we’re really happy with the material choice because we know from all our other campaigns with VGs that they last. It doesn’t matter whether it’s sun, rain, ice, snow. These products can survive out in the field for 20 years. Allen Hall: That’s one of the things I’ve noticed, uh, looking at a lot o- of blade photos with OEM trailing edge serrations. That the little triangles on the back edges break off.  Nicholas Gaudern: Yeah. And I think- There’s  Allen Hall: a lot of them. I was shocked on  Nicholas Gaudern: some sites. One thing you have to be very careful as well is, is lifting and handling as well. Oh. So, you know, sometimes if these products are installed in the factory, then how do you safely transport that blade and lift that blade?  Allen Hall: You really can’t.  Nicholas Gaudern: So in some ways it’d be better if you put them on at site, but obviously I, I know that’s not always possible. No. So we’re typically acting, um, as, you know, a retrofit. Mm-hmm. So in that sense we, we minimize a lot of that risk of the, the transport and handling that the OEMs may have to deal with.  Allen Hall: So [00:21:00] what’s next for Power Curve? What’s h- happening this summer?  Nicholas Gaudern: So we’re gonna be really pushing to get Silent Edge and Dragon Scale out in the field more. Yeah. Um, Dragon Scale is, is really exciting, and we’re gonna get our, our first, uh, turbines in different countries equipped with these products. And Silent Edge, uh, we’re currently putting some of the finishing touches on the, um, the tooling, the injection molding tooling. So the part we have in front of us, this is actually one that we had in the wind tunnel. So this one here is a 3D print. A very nice 3D print. Oh, yeah, it’s- Uh, it’s had vapor smoothing on it, so the surface- It is really smooth is, is super nice. And you can put these out in the field. So the, the trial with Statkraft was actually with 3D-printed components. If you wanna do a trial for a few months, it’s very possible to do it with 3D prints. Oh. And I, I think they’d actually last way, way longer than that, but, you know, the test was designed to put them on, measure them, take them off again. Yeah. And that’s what we did.  Allen Hall: Offshore.  Nicholas Gaudern: Mm.  Allen Hall: Uh, uh, w- we’ve had some people write into the podcast talking about offshore wind turbines. And in the States, offshore wind turbines are [00:22:00] usually 10, 15, 20 miles from the shore, but that’s not always the case. Over in Japan and some other areas, the turbines are pretty close to shore. Nicholas Gaudern: Yeah, def- They’re  Allen Hall: almost-  Nicholas Gaudern: They’re definitely near-shore …  Allen Hall: they’re almost- Yeah. Yeah, yeah … onshore turbines, but because they’re offshore, they get really big, right? So y- you can build a really big offshore turbine. And some of the comments we have received is, “Hey, these turbines are noisy.”  Nicholas Gaudern: Yeah. And, you know, the, the water surface can do some weird things-  Allen Hall: Well, that’s what I wanted to know acoustically. Okay. Yeah. That’s what I wanted to know- Yeah. Yeah … because if you have trees and hills that kind of block the noise- Yeah … that’s easy. But if you have a turbine and you live on the, essentially the beach- Yep … or real close to the shore- Yeah … that turbine is right there. In some cases in Japan, it’s not very far. Yeah. You can see it.  Nicholas Gaudern: Particularly on a still day, you know, when you have a very flat water surface, that can mean that sound is able to propagate a little bit further than maybe it otherwise would.  Allen Hall: So is there a, a real need then to pay attention to the acoustics and noise- Yeah … coming off of offshore wind turbines? Nicholas Gaudern: [00:23:00] I think, uh, c- certainly the near-shore, the things you’re describing now. Yeah. Offshore’s an interesting question because I think often, if I think about the UK and, and Denmark, they are quite offshore, and I think in that, in that sense, the noise is much less of a, a concern. And I think it may be more driven by regulatory r- requirements- Mm-hmm than actual, you know, neighbor complaints perhaps. So noise is interesting because people put serrations on for different reasons. Yeah. Some put them on because there’s a regulation. Yeah. Uh, some put them on because they want to be shown to being a good neighbor, you know, doing the best they can to reduce noise- We should  Allen Hall: try to- Nicholas Gaudern: which we should absolutely be doing …  Allen Hall: do that every time we can.  Nicholas Gaudern: And some are doing it because they have curtailment on their turbines.  Allen Hall: Yes.  Nicholas Gaudern: So in order to meet a regulation perhaps, they have to basically turn down the turbine, and it means that it spins slower. And if it spins slower, the noise is lower, sure. But the power output is also lower. And what we found is that on some turbines that are in noise modes, they’re losing 3, 4, 5% AEP- Ooh. Ouch … [00:24:00]every year because they’re having to turn down the turbine to meet a regulation or to, to satisfy, you know, uh, neighbor relationships. But just imagine what that means for finances if you put a serration on. You can turn the turbine up again, which you’re now addressing the noise at the source, so you don’t actually have to stop it spinning slower. You’re actually killing the noise where it’s being generated.  Allen Hall: So there’s a big financial incentive- Yes … to look at trailing edge and try to quiet them as much as you can, particularly onshore. I think that case has- Yeah … been well made over time. I’m always shocked that a lot of operators that, uh, even in the US Midwest, and we s- we drive around quite a bit in the Midwest, there’s a lot of turbines that are near homes.  Nicholas Gaudern: Yeah,  Allen Hall: absolutely. Y- you know, there’s one or two or three homes. This isn’t like there’s a suburb right there, but there are homes out there, and, and they would like to have enjoyment of their property. Yeah, of course. And if you can knock down the noise a little bit, it would make it  Nicholas Gaudern: a much more pleasant place. Well, if you take, you know, if you take 30-plus percent off the perceived loudness, that’s, you know-  Allen Hall: Oh, that’s very noticeable … that’s gonna, that’s gonna make a difference. Yeah, you’ll get a thank you letter- Yeah for [00:25:00] sure. So that’s exciting. The- Yeah … all this is exciting. It- It’s  Nicholas Gaudern: gonna be, it’s gonna be a really great summer, I think, to get more of these components out in the field.  Allen Hall: So if, uh, an operator or an asset manager wants to get ahold of Power Curve, understand what Silent Edge is, and how to get it installed or put some dragon scales on this season, how do they do that? Nicholas Gaudern: So you can check out our website, uh, powercurve.dk. That has all of our contact details on. Uh, you can find me on LinkedIn, uh, as well. I’m often around these, uh- … events that we find- Yeah … uh, in different countries. So no, look, look us up, reach out by email, phone, whatever, and we’d be very happy to talk to you. Allen Hall: Or reach out to the India office.  Nicholas Gaudern: Yes, that’s something that we’re hoping to have up and running, uh- So  Allen Hall: if you’re  Nicholas Gaudern: in India- …  Allen Hall: later this year. Yeah. Reach out. Yeah, that, that’s gonna be an exciting advancement. Yeah. Great. For  Nicholas Gaudern: sure.  Allen Hall: Nicholas, it’s great to have you on the podcast again.  Nicholas Gaudern: Nice talking to you, [00:26:00] Allen.

Back from the ADSA annual meeting in Milwaukee, Brad shares highlights from several calf-focused dairy studies. This episode covers new research on colostrum management for beef-on-dairy crossbred calves, including how feeding practices differ between retained dairy heifers, beef-on-dairy calves, and calves not kept on farm.Brad also reviews a study comparing fixed-age weaning with starter-intake-based weaning in Holstein and Angus-Holstein calves, plus new work using ear tag sensors to track calf behavior, rumination, eating, and activity through 150 days of age. The episode wraps up with research from the University of Florida on colostrum yield, quality, and genetics, including how season, parity, calf sex, gestation length, and days dry can influence colostrum outcomes.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad shares two studies He presented at the American Dairy Science Association annual meeting. First, he examines records from more than 150,000 lactations to compare genetic predictions for somatic cell score and clinical mastitis. The results suggest that PTA for somatic cell score is more useful for predicting and ranking cows by observed somatic cell count than PTA for mastitis.He also discusses a study comparing Holstein and crossbred heifers for feed intake, methane emissions, rumination, and feeding behavior. Although methane produced per kilogram of feed was similar across breed groups, smaller crossbred heifers consumed four to five pounds less dry matter per day. The findings highlight how genetics, breed, sensors, and precision feeding data could help producers improve herd health and heifer management.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad discusses what he learned about high oleic soybeans at the Four State Dairy Management and Nutrition Conference in La Crosse, Wisconsin. High oleic soybeans are gaining attention in dairy nutrition because they can provide both rumen undegradable protein and a more rumen-friendly fat source, potentially reducing the need for purchased protein and fat supplements.The episode covers how high oleic beans differ from conventional soybeans, why roasting quality matters, and how measures like protein dispersibility index help determine whether beans are under- or over-processed. Brad also reviews feeding rates, farm case studies showing milk fat and energy-corrected milk responses, possible cost savings, and the pros and cons of adopting high oleic beans on dairy farms.Overall, high oleic soybeans are not a silver bullet, but they may offer dairy producers another tool for improving ration economics, milk components, and on-farm feed production when managed carefully.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

A case of New World screwworm was recently identified in a three-month-old calf in Zavala County, Texas, near the Texas-Mexico border. In this episode, Brad breaks down what New World screwworm is, why it matters to livestock producers, and what signs to watch for in cattle and other animals. He explains how the larvae infest live tissue, how the pest spreads, and why early detection, reporting, quarantine, and treatment are key to preventing further spread.The episode also clears up common myths, including whether screwworm spreads animal-to-animal or person-to-person, whether whole herds must be culled, and whether recovered animals can enter the food supply. Brad also discusses past eradication efforts using sterile flies, current treatment options, and the importance of producer awareness, especially for those in areas at higher risk. Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad discusses new research comparing dairy heifers raised on pasture versus in confinement, focusing on studies from Wisconsin and Minnesota. Both studies found that pasture-raised heifers were slightly lighter and gained less before calving, but they reached calving at a similar age and showed advantages after freshening. Pasture-raised animals had higher dry matter intake, fewer health issues in the Minnesota study, and stronger first-lactation milk production, especially under rotational grazing systems. Brad also highlights the economic upside: pasture systems reduced heifer feed costs and, in the Wisconsin study, improved income over feed cost during lactation. The episode makes the case that raising dairy heifers on pasture can be a practical strategy to lower rearing costs without sacrificing, and potentially improving, future milk production. Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

 Brad shares updates from the University of Minnesota Morris dairy herd, including cows heading out to spring pasture, a recent Holstein classification, and highlights from several high-scoring cows. He then revisits University of Minnesota crossbreeding research comparing Holsteins with Viking Red and Montbéliarde crosses. The results show that crossbred cows often had better fertility, lower health treatment costs, improved survival to later lactations, and higher daily profitability, even when milk volume was sometimes lower than Holsteins. Brad also connects these findings to current beef-on-dairy calf research showing health advantages from crossbreeding, especially fewer scours and digestive problems.

In this episode of The Moos Room, Brad discusses spring pasture challenges in western Minnesota, including dry conditions, temperature swings, and slowed grass growth. With summer heat on the horizon, the focus shifts to heat stress in dairy cows and how precision technologies, especially internal bolus sensors, can help farmers identify problems earlier.Brad shares observations from cows monitored with Smaxtec boluses, including rumination, internal body temperature, and water intake data. He also reviews research from the University of Minnesota herd showing that rumination may start dropping at lower temperature-humidity index levels than traditional industry thresholds suggest. Conventional cows showed rumination declines around a THI of 64, while pasture-based organic cows showed declines closer to 58.The episode highlights why waiting for milk production losses may be too late when managing heat stress. Instead, rumination, body temperature, water intake, shade, cooling systems, and feeding strategies can all play a role in protecting cow comfort and performance before visible signs of heat stress appear.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory

Brad takes a closer look at FerAppease, a synthetic analog of the maternal bovine appeasing substance that is gaining attention in both the dairy and beef industries. He explains how the product is designed to reduce stress in cattle during events like breeding, weaning, dehorning, transportation, calving, and dry-off.The episode highlights recent research in lactating Holstein cows showing that applying FerAppease at the time of artificial insemination increased pregnancy per AI from 47.7% in control cows to 60.2% in treated cows. Brad also walks through the potential economics, estimating a strong return on investment when improved pregnancy rates are valued at the farm level.Brad then discusses a calf study looking at FerAppease use around disbudding. Treated calves showed signs of reduced stress, including lower cortisol measures, and had improved average daily gain shortly after disbudding. While more research is needed, Brad notes that FerAppease may be a useful non-antibiotic, non-hormonal tool for reducing stress and improving outcomes during key management events.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Virtual fencing is gaining attention in livestock production, and this episode breaks down what dairy producers need to know before trying it. Brad explains how virtual fencing uses GPS-enabled collars or ear tags, audio cues, and electrical cues to manage grazing animals within digital boundaries. He also shares lessons from training heifers with virtual fence collars, including the adjustment period, the importance of using a physical fence during training, and how animals typically learn the system within about a week.The episode also compares several virtual fencing systems available to U.S. producers, including Vence, Gallagher, Halter, and Nofence. Brad walks through major considerations such as collar weight, cellular versus base station connectivity, battery life, subscription fees, and upfront costs. He also discusses how virtual fencing may compare financially with traditional physical fencing and why more research is needed to understand its fit in dairy grazing systems.Brad also previews upcoming virtual fencing work at the University of Minnesota West Central Research and Outreach Center, where multiple systems will be tested with dairy cattle to better understand labor needs, cost, practicality, and overall performance in real grazing conditions. Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

This episode highlights new research on Salmonella Dublin in dairy-beef systems and what it means for calf health and farm management. The disease is a major threat to young calves, causing severe illness and high mortality, while often spreading silently through carrier animals and contaminated environments. New PCR testing shows the pathogen is far more common than traditional methods suggest.Key risk factors include frequent introduction of new calves, mixing animals post-weaning, and human movement (boots, equipment) spreading contamination between areas.Bottom line: Salmonella Dublin isn't random—it reflects management. Strong biosecurity, better calf flow, delayed weaning, and improved monitoring are critical to reducing risk.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Spring may be slow to arrive in Minnesota, but research season is heating up. In this episode of The Moos Room, Brad revisits a large Minnesota-based study exploring the true cost of health events in dairy cows—and why tracking cost, not just disease incidence, could transform genetic selection and farm profitability.Using data from thousands of Holstein cows across multiple herds, the team found that health costs are heavily concentrated in the first 30 days of lactation, when cows face metabolic stress from calving and high milk production. However, issues like lameness and mastitis continue to accumulate costs throughout the lactation, especially in older cows. In fact, total health costs more than double from first to later lactations, reflecting wear, immune fatigue, and management differences.A key takeaway: management determines cost, but genetics influence risk. While some high-cost conditions (like reproductive disorders) are difficult to improve genetically, others—such as mastitis and metabolic disease—show stronger heritability.The breakthrough insight is that total health cost itself is moderately heritable (~0.25)—much higher than traditional “sick vs. not sick” measures. This means selecting animals based on overall health cost could drive faster genetic progress than current methods.Brad also highlights important genetic and phenotypic relationships: Higher milk production is linked to increased health costs  Lower somatic cell count strongly reduces total health costs  Taller, more angular cows tend to have higher health costs  Shallower udders are associated with better health outcomes From a practical standpoint, the episode emphasizes: The need for consistent, detailed health and cost recording Moving beyond binary disease tracking to full economic impact Incorporating total health cost into sire selection decisionsBottom line: Selecting for lower total health cost can improve profitability, extend cow longevity, and enhance animal welfare—potentially saving tens of thousands of dollars at the herd level in just one generation.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

This episode of The Moos Room dives into new research on agrivoltaics—specifically how forages perform when grown under solar panels in grazing systems. Brad shares results from a recent study evaluating multiple grass and legume species across different solar array designs compared to a traditional pasture.Overall, forage production depended heavily on species and shade level. Cool-season grasses like meadow fescue and orchardgrass performed well under solar panels, sometimes even producing more biomass than in open pasture. In contrast, warm-season species like sorghum-sudangrass struggled under shaded conditions. Legumes such as red clover maintained strong performance and contributed to improved forage quality.One of the biggest takeaways was that while heavier shade can reduce total biomass, it often improves forage quality. Grasses grown under solar panels showed higher crude protein and greater fiber digestibility, especially in more shaded systems. This suggests agrivoltaic systems can still produce high-quality feed, even when yield is slightly reduced.The episode highlights that selecting the right species—particularly shade-tolerant cool-season grasses and legume mixtures—is key to success in grazing-based solar systems. Ultimately, agrivoltaics offers a promising opportunity to combine livestock production with renewable energy, providing both high-quality forage and an additional revenue stream for farmers.Agrivoltaic arrays and effects of forage biomass and nutritive value of grasses and legumes for grazing dairy cattlehttps://www.jdscommun.org/article/S2666-9102(26)00073-6/fulltextAgrivoltaics Webinar Cattle and Kilowatts 4/14Sponsored by University of Minnesota ExtensionOur first webinar is April 14th, 2026 5pm CT.Register for the zoom link: z.umn.edu/cattlekilowattsCattle and kilowatts webinar: Real-world solar grazing in practiceJoin the University of Minnesota Extension for an in-depth webinar featuring pioneers of cattle solar grazing.

 In this episode of The Moos Room, Brad shares insights from a recent study at the University of Minnesota Morris dairy focused on reducing mastitis and improving behavior in first-lactation heifers. The research tested a simple, low-labor strategy: bringing heifers into the parlor once per week for three weeks before calving, gently acclimating them, and applying a 1% iodine teat dip. Results showed that trained heifers were calmer, easier to milk, and significantly less likely to kick during milking, improving both animal welfare and milker safety. While overall clinical mastitis rates did not differ, the treatment notably reduced Staphylococcus aureus infections, with untrained heifers having five times greater odds of infection shortly after calving. The episode highlights how small, proactive management steps before calving can break the cycle of stress, poor behavior, and disease—offering a practical approach to improving transition success in dairy heifers.

 Spring calving is underway in Minnesota, and with it comes renewed focus on the booming beef-on-dairy market. In this episode, Brad dives into current calf prices—highlighting the strong premium for beef-cross calves—and breaks down new research comparing Holstein and beef × dairy calves under the same management. Across studies from Canada and Brazil, crossbred calves consistently showed advantages: lower rates of diarrhea, fewer treatment interventions, improved starter intake, and greater feed efficiency. While respiratory disease incidence was similar, crossbreds recovered faster and required fewer treatments. By 84 days, crossbred calves were heavier and more efficient to raise, reinforcing long-standing evidence that heterosis improves calf performance. The takeaway is clear: beef-on-dairy calves not only bring strong market value but also demonstrate biological and economic advantages during the pre-weaning phase—making them an increasingly attractive strategy for dairy producers navigating volatile milk markets. Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

On this spring episode of The Moos Room, Brad dives into the seasonal return of flies and shares results from a recent horn fly vaccine study conducted at the University of Minnesota's WCROC. Horn flies—common in pasture-based systems—cause significant irritation, blood loss, and production losses in cattle, and their rapid life cycle makes them difficult to control, especially with increasing insecticide resistance.The study evaluated a Medgene horn fly vaccine designed to disrupt the fly's ability to take a blood meal, ultimately reducing reproduction. Researchers vaccinated about half of the cows and heifers across organic (pasture-based) and conventional (dry lot) systems and tracked fly populations throughout the summer. While no differences were observed for face flies or stable flies—as expected—the vaccine showed promising results for horn flies. There was little effect in conventional cows, but in pasture-based animals, especially heifers, vaccinated groups experienced a consistent 30–40% reduction in horn fly numbers compared to controls.Overall, the findings suggest that horn fly vaccination could be a valuable new tool—particularly for grazing and organic dairy systems—to help manage fly pressure and improve animal well-being over time.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad shares a spring dairy update and breaks down newly released national performance metrics from the Council on Dairy Cattle Breeding, offering a snapshot of what the U.S. dairy herd looks like today. He also touches on a major industry headline—Zoetis' planned acquisition of Neogen's animal genomics business—and what that could mean for dairy genetics going forward.A big part of the episode focuses on the red-hot calf market, especially for beef-on-dairy crosses. Brad highlights eye-popping prices from Minnesota sale barns, where Holstein bull calves and beef-cross calves are bringing in far more than producers would have expected just a few years ago. He reflects on how dramatically the economics of beef-on-dairy have changed and what that could mean for breeding decisions on dairies this year.The second half of the episode dives into the new national herd data, including milk production, components, somatic cell counts, herd size, and breed distribution across the country. Brad walks through where Holsteins, Jerseys, crossbreds, Brown Swiss, Guernseys, Ayrshires, and Milking Shorthorns stand today, and which states are leading in cow numbers and herd size. It's a practical, numbers-driven look at dairy trends in the U.S. and a useful update for anyone interested in genetics, herd demographics, and where the industry is heading.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad explores a recent study comparing two common calf-feeding methods: open buckets and nipple buckets. While most U.S. dairies rely on open buckets because they allow calves to drink quickly and reduce chore time, the research looked at how these systems affect calf growth, digestion, and behavior.The study followed individually housed calves fed six liters of milk per day until weaning at eight weeks. Calves fed with open buckets finished their milk much faster, often in under two minutes, while nipple-fed calves took about five minutes because the system mimics natural suckling. Despite the difference in drinking speed, both groups had similar growth rates and physical development.However, behavior and digestion told a more interesting story. Calves fed with open buckets consumed more starter grain and spent more time ruminating, but they also showed more non-nutritive oral behaviors like sucking on pen fixtures or other calves—likely because their natural suckling drive wasn't satisfied. Nipple-fed calves showed fewer of these behaviors, had slightly firmer feces, and exhibited metabolic signals suggesting improved digestion.Brad breaks down the trade-offs for dairy producers: open buckets offer efficiency and faster feeding, while nipple buckets may better support calf welfare and natural behavior. The episode highlights how feeding systems can influence calf behavior, digestion, and management decisions on dairy farms.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

 Brad shares results from a large national research project examining somatic cell count (SCC) and mastitis risk in U.S. organic dairy herds, using more than 2 million DHI test-day records from 430 farms across 31 states. The discussion highlights how SCC is influenced by multiple factors, including cow age, stage of lactation, milk production, breed, season, region, and herd size. Older cows, early-lactation animals, and lower-producing cows were most likely to have elevated SCC, while heat stress—especially during summer months—and larger herd size significantly increased risk. Because organic systems cannot rely on antibiotics, Brad emphasizes prevention strategies such as improved fresh-cow management, heat abatement, careful monitoring of chronic cows, and strong milking hygiene as key tools for controlling mastitis and maintaining milk quality.

In this solo episode, Brad shares a few recent herd-health case studies from his dairy, highlighting the value of diagnostics and transparency.He walks through two calf losses—one at 60 days old and another at 9 months. Both animals had been treated for common issues but continued to decline. Necropsies revealed severe heart abnormalities in each case (thin, underdeveloped ventricles), pointing toward possible genetic or nutritional causes. The takeaway: without a necropsy, these would have remained unexplained losses.Brad also discusses a recent abortion in a dry cow. Diagnostic testing ruled out BVD and IBR and identified Citrobacter sp., an environmental organism found in manure, soil, and bedding that can contribute to abortions. He suspects environmental exposure in wintered dry cows may have played a role.Overall, the episode emphasizes investigating unexpected losses, using lab diagnostics, and learning from on-farm challenges as spring calving approaches.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory

Emily and Brad re-record this episode of The Moos Room after a technical glitch wiped out Emily's audio—and dive into a big question: What does the dairy cow of the future look like?Inspired by a recent Journal of Dairy Science paper, they move beyond the classic Holstein vs. Jersey debate to discuss a more balanced vision. Instead of selecting for maximum milk at all costs, the future cow will prioritize resilience, fertility, longevity, feed efficiency, and environmental sustainability.They explore how genomics must be paired with real-world performance data (phenotypes), how precision technologies and robots are shaping breeding goals, and why moderate size and genetic diversity matter. From methane efficiency to beef-on-dairy and even gene editing, the episode highlights how breeding decisions today are shaping a smarter, more sustainable cow for tomorrow.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Calf prices are making headlines, and in this episode Emily and Brad are joined by UMN Extension beef educator Melissa Runck to talk through what today's hot beef and beef-on-dairy markets mean for producers.They discuss why newborn beef-cross calves are bringing record prices, how that cash can help dairy farms when milk prices are low, and what the latest Cattle on Feed report tells us about declining inventories and producers' reluctance to keep heifers as replacements. The group then dives into beef-on-dairy sire selection, emphasizing realistic goals over the search for a “perfect” bull, the importance of calving ease and fertility, and when carcass traits and indexes matter based on how calves are marketed.The episode wraps up with a practical look at facilities and management, underscoring that good management—more than perfect buildings—drives success with beef-on-dairy cattle.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

On a warm-for-February day in Minnesota, Brad dives into two topics shaping today's dairy landscape: changing dairy herd demographics in the Upper Midwest and new research on dairy cow preferences for grooming brushes.The episode opens with a look at dairy farm numbers in Minnesota, where the state has lost nearly 37% of its dairy farms since 2019—dropping from 2,567 to just 1,622 operations. Brad breaks down herd size distribution, showing Minnesota remains dominated by small herds (especially 50–100 cows), even as the number of very large herds continues to grow. He also highlights where dairy farms are concentrated geographically, with Stearns County leading the state, and notes that seven Minnesota counties now have no dairy farms at all.Brad then compares Minnesota to Wisconsin, which still has over 5,100 licensed dairy farms. Wisconsin's dairy industry includes a notable number of goat dairies (nearly 400) and a small but interesting presence of sheep dairies. He walks through the top dairy counties in Wisconsin, illustrating how dairy production clusters in central, southwestern, and Green Bay–adjacent regions.In the second half of the episode, Brad discusses a new Purdue University study examining dairy cow preferences for grooming brushes. Researchers compared three brush types—swinging and rotating, swinging only, and stationary—and found that more than 75% of cows preferred the swinging, rotating brush. Cows spent several minutes grooming their heads, backs, and rumps, with rotating brushes offering the most engagement and relaxation. While stationary brushes were used mainly for head scratching, the study suggests that offering a variety of brush types may give cows valuable choice and enrichment.Brad wraps up by reflecting on what these trends mean for dairy farm viability, animal welfare, and management decisions—leaving listeners with practical insights and plenty to think about.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad checks in from a brutally cold stretch in western Minnesota (30–40°F below zero), noting the cows are handling it well and somatic cell counts tend to run low in the extreme cold. He then walks listeners through how he thinks about sire selection in his research herd—mostly Holsteins, plus Jerseys and a few “colored breeds” like Norwegian Red, Montbéliarde, and Normande.His selection philosophy is clear: he starts with Net Merit, but he doesn't blindly follow it. Brad says he doesn't chase milk pounds, and he wishes the major indexes put more emphasis on fertility. Instead, his priorities are:Low somatic cell count / mastitis resistanceHigh fertility (DPR, heifer and cow conception rate)Productive life and durabilityManaging inbreeding (using outcross sires when needed)A major current push: polled genetics (especially homozygous polled sires to speed progress)Brad shares many of the specific bulls he's using and why—including proven sires with lots of daughters for reliability, plus a smaller “sprinkling” of genomic bulls (often because they're polled). He highlights using popular Holstein sires like Genosource Captain, polled-focused options like Leyser PP and Seabrook PP, plus a few high-type outcross bulls mainly to reduce inbreeding, even if their production or functional traits aren't his usual preference. He also lists several Select Sires bulls (including polled sires) that fit his functional-trait focus.On the Jersey side, he emphasizes moderate cows with fertility, productive life, and livability, again weaving in polled where possible. For crossbreeding, he calls out Norwegian Red bulls with strong U.S. proofs for fertility and functional traits, and he mentions finding limited polled options in Montbéliarde but using them when available. He wraps by summarizing what listeners should take away: his herd is moving deliberately toward polled, backed by a USDA grant, while still prioritizing fertility, longevity, mastitis resistance, and outcrossing to manage inbreeding—and he invites feedback and debate from listeners.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this solo episode of The Moos Room, Brad shares “hot off the press” research on circadian rhythms in dairy cows and what long-term sensor data can tell us about cow welfare. Drawing from a study presented at the International Precision Dairy Farming Conference in New Zealand, the episode explores how daily and seasonal behavior patterns—such as eating, rumination, activity, and rest—are shaped by environment, management, and breed.Using more than 10 years of CowManager sensor data from the University of Minnesota research herd, Brad walks through how different breeds (Holsteins, crossbreds, graze-cross cows, and 1964 Holstein genetics) show distinct seasonal rhythms. Results revealed clear breed differences in eating time, rumination, overall activity, and inactivity, with graze-cross cows showing the strongest seasonal patterns and more stable alignment with environmental cues—suggesting better adaptability to pasture-based systems.The episode highlights how disruptions to circadian rhythms—caused by inconsistent lighting, feeding schedules, or confinement—may be linked to stress, immune suppression, lameness, mastitis, and reduced fertility. Brad discusses how precision dairy technologies offer a powerful, non-invasive way to monitor these rhythms and potentially detect welfare issues before clinical signs appear.The episode wraps up by looking ahead to future research linking behavior patterns directly to health and productivity outcomes, and how better alignment of management practices with natural cow rhythms could improve welfare and resilience on dairy farms.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this solo “Emily Show” episode of The Moos Room, Emily takes a timely look at mastitis management during the winter months. While mastitis and high somatic cell counts are often associated with summer heat and humidity, Emily reminds listeners that cold weather brings its own risks and requires just as much attention to udder health.She begins by emphasizing the foundation of mastitis prevention: clean, dry bedding, cow comfort, and good ventilation. These basics reduce stress on cows and limit bacterial exposure, which is especially important when winter conditions can lead to damp or dirty housing.Emily then dives into winter-specific milking routine challenges, especially when cows are exposed to cold temperatures after milking. Wet teats are at much higher risk of frostbite, which can permanently damage teat ends and predispose cows to infections. While this makes some producers hesitant to use post-milking teat dip in cold weather, Emily strongly advises against skipping this crucial step. Instead, she shares a practical guideline: “Don't skip dip—but don't drip.” In other words, apply teat dip thoroughly, but avoid excessive dripping that can freeze. Letting cows stand for 20–30 seconds after dipping and wiping off excess dip before they go outside can provide protection against both mastitis and frostbite.She also discusses udder hair management, noting that long hair can trap teat dip, manure, and moisture. Options like singeing or clipping udders can help keep teats cleaner and drier, especially in winter.Finally, Emily highlights the role of nutrition in mastitis prevention. Cold stress increases a cow's energy needs, and inadequate nutrition can weaken immune function. Ensuring cows receive enough energy, protein, vitamins, and minerals helps support immune defenses and overall udder health. Working closely with a nutritionist during the winter is key.Emily wraps up by reminding listeners that even if mastitis seems less severe in winter than in summer, it still requires consistent attention year-round. With proper milking routines, clean housing, good nutrition, and smart winter management, producers can protect teat health and keep somatic cell counts in check all season long.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In the first episode of 2026, Emily and Brad kick off a New Year's “resolution” to record more episodes together and dive into one of their favorite themes: management. The conversation is sparked by a German case study Brad found that followed 10 German dairy herd managers (average ~600 cows; range 200–1,200) for three weeks, tracking their work minute-by-minute to see how managers spend time—and what actually drives herd performance.The key concept is “controlling activities,” defined as proactive checks and analysis (not just reacting and “putting out fires”). They break these into three categories: animal controls (pen walks, fresh/sick cow monitoring, reviewing sensor alerts), feeding controls (bunk/refusal checks, feed sampling, monitoring mixing and storage), and process controls (reviewing herd records, equipment checks, ventilation/manure systems, cleanliness).A big takeaway: herd managers spent much of their day on communication and logistics, while only about 15% of time went to controlling activities (animal ~9%, feeding ~1%, process ~5%). Yet the study found that performance wasn't linked to total hours worked, but to how much time was dedicated to these proactive controls. Farms where managers spent more time on controlling activities showed better outcomes, including lower mortality, lower somatic cell count, higher lifetime production, and reduced youngstock losses.They also highlight a concerning “disconnect” around feeding: managers often had minimal involvement in feed-related controls even though feed is a major cost and driver of health and production. The episode closes with practical guidance for any farm size: prioritize time intentionally, increase proactive controlling activities (even slightly), and ensure herd managers stay connected to the feeding process—setting the tone for a more efficient, resilient 2026.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In the final episode of 2025, Emily and Brad reflect on another big year for The Moos Room, marking more than 300 episodes since launching in 2019. They look back on key 2025 topics, including real-world dairy case studies from the Morris Research Dairy, health and safety conversations, emerging disease issues, beef markets, virtual fencing, and growing interest in agrivoltaics.Brad highlights the value of openly sharing on-farm challenges—from calf health issues to nutrition troubleshooting—so listeners can learn alongside the research process. Emily shares how 2025 deepened her understanding of virtual fencing, renewable energy in agriculture, and farm safety, while continuing to champion sunscreen use year-round.Looking ahead to 2026, they preview upcoming projects and episodes on virtual fencing, agrivoltaics, genetics, feed efficiency, and a new study raising purebred Angus calves in a dairy system. They also hope to expand global perspectives on livestock and agriculture and invite listeners to suggest topics, guests, and on-air case studies.They close by thanking listeners for another year of support and looking forward to more conversations in 2026.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this short solo episode of The Moos Room, Emily takes the mic to talk about managing holiday stress through setting healthy boundaries. With the holidays approaching, Emily shares practical guidance on navigating family dynamics, uncomfortable conversations, and competing demands on time and energy.She outlines three simple steps for setting boundaries—being clear and direct, stating what you need, and accepting any discomfort that may follow—and walks through real-world examples such as saying no, redirecting conversations, asking for time, and stepping away when needed. Emily emphasizes that boundaries can be temporary or permanent, and that setting them is an important form of self-care.The episode closes with a reminder that boundaries help reduce unnecessary stress, support resilience, and contribute to healthier relationships. Emily encourages listeners to reflect on their own needs this holiday season and to remember that taking care of yourself is not selfish—it's essential.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this episode of The Moos Room, Brad dives into a landmark new study examining the effects of short- and long-distance transport on the health, survival, and growth of pre-weaned dairy and dairy–beef crossbred calves. Drawing on data from nearly 392,000 calves across multiple farms and transport durations (ranging from 30 minutes to 24 hours), the study challenges common assumptions about calf transport. Surprisingly, mortality upon arrival was extremely low and unaffected by transport length. Differences in mortality by weaning (60 days) were also modest and, importantly, were driven far more by early-life factors than by time spent on the truck.The discussion highlights colostrum management as the single most critical factor influencing calf outcomes. Calves fed two colostrum meals had higher serum protein levels, significantly lower rates of failure of passive transfer, and were about 50% less likely to develop diarrhea—one of the leading causes of pre-weaning mortality. Other key drivers of calf survival included diarrhea, pneumonia, dam parity, gestation length, and birth season, with transport duration explaining relatively little of the variation in outcomes. Brad emphasizes that a calf's “destiny is largely sealed before the wheels start rolling,” underscoring that management decisions made at birth—especially colostrum feeding, dam health, and environmental stress mitigation—matter far more than transport distance alone.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this episode, Brad and Emily welcome a special guest: Dr. Angie Varnum, the University of Minnesota Extension's new livestock veterinarian. After some banter about Minnesota winters—and a classic round of The Moos Room's “super-secret” cattle breed questions—the crew dives into Angie's unique path to Extension.Angie shares how she went from growing up in suburban Maple Grove to studying Spanish education, teaching in schools, and eventually being inspired to pursue veterinary medicine. Her training and work took her across the western U.S., where she gained experience in beef and dairy systems before returning to Minnesota to practice large-animal medicine. Her love for both animals and education ultimately led her to Extension.The conversation explores:How Angie's Spanish language background shapes her work and the opportunities it creates for better outreach and training with Spanish-speaking livestock employees.Current and emerging livestock health concerns, and the importance of distinguishing real risks from media frenzy—while still preparing producers with good information.The evolving role of veterinarians in dairy and beef systems, from herd health and data-driven decision-making to the value of strong producer–vet relationships.Animal behavior and welfare science, an area Angie is especially passionate about integrating into herd health discussions.Angie also highlights upcoming Extension programs she'll be involved in, including the new Artificial Insemination School, Beef Quality Assurance certification sessions, Cow/Calf Days, and several small ruminant programs—from webinars to hands-on lambing and kidding workshops.It's a fun, thoughtful conversation introducing a new member of the Extension livestock team and setting the stage for exciting work ahead.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

UMN students, faculty and a high schooler reflect on screen time, phone bans and what it takes to truly unplug

In this solo episode of The Moos Room, Brad dives into a deep, honest look at production challenges in the University of Minnesota dairy herd and the nutrition and management factors that may be holding cows back. After noticing low udder fill during classification and reviewing herd data, Brad confirms a troubling trend: cows across all lactations are producing 20–30% less milk than predicted. Early-lactation health issues—ketosis, metritis, and retained placentas—are also more common than they should be, especially in first-lactation animals.A recent visit from an outside nutrition team helped uncover several key issues contributing to poor performance. Brad walks listeners through what those “fresh eyes” found across young stock, calves, dry cows, and both the organic and conventional lactating herds. From overconditioned heifers to transition problems at weaning, ration inconsistencies, possible ingredient imbalances, and major concerns with hammer-mill screen size causing undigested corn to pass straight through cows—each discovery points to opportunities for improvement.The conversation also highlights the importance of forage management, including the need for a silage facer, better bunk management, and a long-overdue TMR audit to evaluate mixing order, load prep, refusals, shrink, and ration consistency.Throughout the episode, Brad emphasizes transparency and the value of bringing in additional perspectives. Even well-managed dairies can develop blind spots, and small issues add up fast when milk is left on the table. He outlines the farm's next steps and promises future updates as changes are implemented.If you're interested in nutrition, transition cow health, TMR audits, or practical herd-level troubleshooting, this episode is a real-world case study in identifying problems and planning for better performance.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad and Emily reunite on the podcast to dive into an essential—and timely—topic: farmer mental health. With fall wrapping up and winter on the horizon, stressors on the farm shift and often intensify. Emily shares updates on her recent travels and outreach work in farm safety, health, and wellness, highlighting the seasonal rise in mental health–related concerns across rural communities.Together, Brad and Emily walk through:Why stress is so high right now — uncertainty in markets, weather, disease, economic pressure, and social isolation.Common mental health concerns in farmers, including chronic stress, anxiety, and depression.Key warning signs to watch for in yourself and others—physical symptoms, behavioral changes, and emotional red flags.How to reach out when you're concerned about someone, and why it matters more than people realize.Barriers rural residents face when accessing mental health care, including service shortages and stigma.University of Minnesota Extension's work supporting mental health, including training programs like COMET, resources on ambiguous loss, and broader regional efforts to make help more accessible.Emily emphasizes that checking in, offering support, and connecting people to resources can make a meaningful difference. The episode wraps with reminders that it's okay to not be okay—but it's not okay to keep it to yourself. Brad and Emily also point listeners to a long list of mental health and farm stress resources in the show notes, including Emily's recent appearance on RFD-TV discussing this very topic.COMET: Changing our mental and emotional trajectory TrainingAmbiguous loss and farmingUMN Extension Farm Safety and Health webpageMinnesota Farm Stress resourcesFarm Aid Farmer Resource NetworkQuestions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory

Brad recaps a fall road trip with the Minnesota dairy extension team to South Dakota's rapidly growing I-29 dairy corridor, highlighting what innovative farms are doing to boost efficiency, cow health, and profitability. Along the way, they tour the Bel Brands plant in Brookings, where milk from about 10,000 cows a day is turned into those familiar Babybel snack cheeses, and hear how the plant's demand for high-protein milk is shaping local production.On the farm visits, Brad digs into why one 1,700-cow dairy is ripping out a barn full of robots after just a few years—citing software headaches, maintenance demands, and an extra dollar per hundredweight in cost—and how they're using strict 5-minute milking times and strong beef-on-dairy markets to stay competitive. He then visits a Holstein dairy using parlor timers, FutureCow brushes, genomic testing, Akushi (red Wagyu) beef-on-dairy crosses, intensive calf biosecurity, and a Danish SKOV ventilation system to keep big groups of calves healthy.The final stop is a 6,000-cow Jersey herd proving Jerseys can be successfully raised in northern climates. Brad shares how they use SenseHub tags on calves from birth, IVF and embryo work for high-value Jersey genetics, fresh-heifer mastitis prevention strategies in recycled bedding systems, and clever pen redesigns to add bunk space.In this episode, you'll hear about:Why one large dairy abandoned milking robots for a parlorHow timers in the parlor are being used to speed up milking and labor efficiencyBeef-on-dairy strategies, from Angus to Akushi crosses and premium Texas marketsNew approaches to calf housing, ventilation, and biosecurityUsing precision technology and genomic data to guide breeding and health decisionsPractical ideas Brad wants to bring home to the U of M dairy, from boot disinfectant to fresh-heifer dry treatmentQuestions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad recaps his trip to dairy farms in the Netherlands and Germany, where robotics, crossbreeding, and creative manure and energy management are everywhere — even on small farms. He visited farms using Lely robots, grass/rye silage-based diets, and small-scale digesters that capture manure methane. Crossbreeding (Holstein × Montbéliarde × Viking Red) is common, driven by goals of longevity, health, and reducing inbreeding.He also saw some surprising management choices: dry cows fed only straw for 60 days (reportedly reducing metabolic issues) and one advisor recommending farmers don't clean calf pens to preserve the microbiome — a concept Brad remains skeptical about.At a dairy technology show and breeding conference, Brad shared research on feed efficiency and methane emissions and learned how European breeders are incorporating resilience and efficiency traits into genetic programs. Overall, Europe's dairy farms showed strong use of technology, a focus on components and longevity, and serious interest in crossbreeding as a labor- and health-saving strategy.Hybrid Genetics YouTube Channel to learn more about some of these FarmsQuestions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this episode, Brad is back from Europe—jetlagged but full of insights from farms and conferences in Germany and the Netherlands. He dives into one of the biggest topics he heard about abroad and at home: Inbreeding in dairy cattle.Brad explains how inbreeding occurs, what it costs farmers economically, and how inbreeding levels have climbed across all major dairy breeds—especially Holsteins and Jerseys. Drawing on recent research from Italy and data from the U.S. Council on Dairy Cattle Breeding, he outlines how increasing inbreeding negatively impacts cow survival, fertility, and long-term profitability.The discussion highlights startling trends—Holstein inbreeding has jumped from 3.7% in the mid-1990s to nearly 11% today, and some genomic bulls now exceed 16%. Brad also touches on historic bulls whose genetics still dominate today's herds, like Elevation and Highland Magic Duncan, and explores whether approaches like crossbreeding, linebreeding, or greater genetic diversity in breeding programs could help slow the trend.Brad concludes with a call to action: farmers, AI companies, and breed associations must prioritize genetic diversity now to safeguard herd health and productivity.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Brad kicks off a solo episode (recorded before a trip to Germany) and turns the mic to rangeland scientist Anna Clare for a deep dive into “the solar savanna”—treating solar arrays on grasslands as functioning grazing ecosystems. She shares early results from Silicon Ranch's Cattle Tracker research on integrating cattle (not just sheep) with PV systems. Brad follows with University of Minnesota's on-farm demos: panel heights that work for cattle, heat-stress reductions, forage performance under panels, and a mobile, battery-equipped shade/solar rig. If you're curious how and when cattle can safely graze under solar, this one's packed with data and practical design tips.Key takeawaysSolar as savanna: Think of arrays as shade “canopies” over grasslands—manage them as grazing systems with soils, roots, pollinators, and large herbivores in mind.Cattle can work under PV: Moving from sheep to cattle is feasible when arrays are designed with animal size/behavior in mind.Panel height matters: In controlled mockups, animal interactions dropped 43% from 2.0→2.5 m and 59% at 3.0 m. Cattle never touched panels; most curiosity was with dampers—a design hotspot.Ecosystem wins: Under-panel zones showed higher soil moisture and lower soil temperatures, favoring cool-season grasses and legumes; regrowth dynamics can improve after grazing passes.Animal welfare benefits: UMN trials showed lower respiration rates and 0.5–1.0 °F lower internal body temperatures during hot afternoons for shaded cows—meaningfully less heat stress.Forage production holds up (or improves): Certain mixes (e.g., orchardgrass, meadow fescue; grass-legume combos) produced equal or greater biomass under panels with no drop in nutritive value.Design for cattle, not fear: After a decade of on-farm experience, Brad's team hasn't seen cattle damage panels; people and tractors are more likely risks than cows.Practical layouts: Keep inverters outside fences, route wiring high/inside racking, and allow equipment lanes; rotational grazing and (potentially) virtual fencing fit well.Innovation on wheels: A 20 kW mobile bifacial shade rig with onboard batteries can power irrigation, fencing, and even an electric tractor—bringing agrivoltaics to wherever cattle need relief.Research & projects mentionedSilicon Ranch – Cattle Tracker: multi-year cattle-PV integration study; Phase 2 is a 4.5 MW Tennessee “outdoor test lab” comparing array vs. open pasture for behavior, space use, health/performance, plus mirrored ecosystem monitoring.Comprehensive literature review (AGU Earth's Future – in press): Maps intersections among livestock–solar–land, identifies six research gaps (integration, layered ecology, modeling, best practices, social dimensions, collaborative science).UMN Morris agrivoltaics demos: Fixed-tilt arrays at 6–8 ft (1.8–2.4 m) leading edge; 0.5 MW pasture array powering campus; vertical bifacial and crop-under-PV pilots coming; EV fast charger powered by cow-shade solar.Who it's forDevelopers, ranchers, extension pros, and policy folks exploring dual-use solar that keeps grasslands working and cattle comfortable.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Emily is back from medical leave (hooray!) and she and Brad dig into an essential topic for every operation: emergency planning. You can't predict every detail, but you can make the first decisions easier when seconds count.What we cover:What an emergency plan is (and isn't): a concise, written set of steps and key info you can default to under pressure.Start with a farm map: access routes, gates/fences, livestock locations, hazardous/flammable materials, and utility shutoffs.Make the red sheet easy to find: an emergency contact list (911 first), then vet, sheriff/emergency management, insurance, milk hauler, feed/suppliers, and owner/manager.Stock the right supplies: standard first-aid kits, a trauma kit with a tourniquet, and consider an AED; plan to keep kits replenished.Three scenario buckets to plan for:Shelter in place (blizzards, extended outages): backup power/fuel, blocked access routes, pared-down chore list, role assignments, keeping people safe.Evacuation (fire, flood, tornado damage): best escape routes for people/animals, which gates to open and in what order, a designated meeting point (and Plan B), and who calls whom.Medical emergencies (injury or health event): known conditions (EpiPens, diabetes, heart issues), where supplies/AED live, basic first-aid/CPR training, clear directions for EMS, and—on larger sites—who meets the ambulance at the road and whether a safe helicopter landing area exists.Mind the paperwork: review insurance coverage before you need it.Keep it simple and living: a few clear steps beat a thick binder no one reads.Resources mentioned:University of Minnesota Extension: Operations contingency plan templates for livestock operations.Extension Disaster Education Network (EDEN): disaster-specific farm resources.Cultivating Change Foundation (Emily & Joe Rand received the Cultivator of Change award).Save the date: Ag for All Conference for LGBTQ+ farmers, ag professionals, and allies — March 7, 2026, Waite Park/St. Cloud, MN.Have questions, comments, or scathing rebuttals?

In this episode, Brad shares his fall updates from western Minnesota before diving into a detailed discussion on genomic testing in dairy herds. Drawing on his experiences from recent farm visits in South Dakota and ongoing University of Minnesota research projects, he explores how producers are using genomics and whether the investment pays off.Brad explains that while some herds use genomic testing solely to decide which animals to breed to beef, he believes the technology's value lies much deeper — in improving herd genetics, managing inbreeding, verifying parentage, and advancing traits like health, fertility, and production components. He outlines the major testing companies (Neogen, Zoetis, and Genetic Visions), their costs (around $37–$42 per animal), and the kinds of data producers can expect from each, including A2 status, horned/polled traits, and wellness indices.The episode also includes two case studies:A small grazing herd where genomic testing clarified breed composition, revealed unknown sires, and identified A2 status across mixed-breed animals.A university research herd exploring polled genetics and crossbred performance, where Brad questions how well current evaluations reflect the true genetic potential of crossbreds like Normande and Montbéliarde crosses.Brad closes by summarizing the practical ways to use genomic information — from strategic breeding and heifer selection to developing niche markets like A2 milk products. His key takeaway: genomic testing can be a powerful tool for herd improvement, but it's only worth the cost when used strategically rather than as a simple breeding filter.Listeners are encouraged to share feedback or questions via The Moos Room's contact page or University of Minnesota Extension channels.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

Host Brad Heins welcomes Becca Weir, a Minnesota native and newly appointed assistant professor of agricultural economics at Penn State. Growing up on a dairy farm near Sauk Centre, Rebecca developed a passion for applying economics to dairy management decisions.In this episode, she shares findings from her University of Minnesota research with Jolene Hadrich, which connected genetic selection (sire Net Merit) with farm-level profitability using data from 2012–2018 Minnesota dairy herds.Key insights:A $100 increase in sire Net Merit was linked to roughly $12,000 more in net farm income—about $87 per cow, higher than expected.The positive relationship held across small, medium, and large herds, showing that investing in genetics pays off for all farm sizes.Traits related to longevity and health—such as livability and milk fever resistance—were the most consistent contributors to profitability.Selecting based on the Net Merit index is more effective than focusing on single traits.Genetics explained about 3% of profitability variation, a small but meaningful share alongside market conditions, management, and input costs.Rebecca also discusses her new role at Penn State, where she'll continue exploring dairy farm management, risk management, and programs like Dairy Margin Coverage to help producers improve economic resilience.Brad closes by reminding listeners that genetics are just one piece of the profitability puzzle—but an important one that can deliver measurable returns for dairy farmers.Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory 

In this episode, Brad shares his firsthand experience with virtual fencing on the University of Minnesota's Morris dairy herd. After a long grazing season, he dives into the reasons he began experimenting with NoFence collars, the training process for heifers, and what he learned about costs, labor savings, and animal behavior.Brad walks listeners through the setup, the challenges of training, and the variation he saw among animals in how quickly they adapted. He highlights both the advantages—like labor efficiency and flexibility—and the limitations, such as collar costs, GPS accuracy, and the need for careful management when mixing groups.Looking ahead, Brad plans to extend the trial to lactating cows next grazing season, a new frontier for virtual fencing in dairy. He also points to upcoming field days and funding opportunities for farmers curious about adopting the technology.Virtual fencing, he concludes, may be the future of grazing management—helping reduce labor while improving flexibility on farms. Questions, comments, scathing rebuttals? -> themoosroom@umn.edu or call 612-624-3610 and leave us a message!Linkedin -> The Moos RoomTwitter -> @UMNmoosroom and @UMNFarmSafetyFacebook -> @UMNDairyYouTube -> UMN Beef and Dairy and UMN Farm Safety and HealthInstagram -> @UMNWCROCDairyExtension WebsiteAgriAmerica Podcast Directory
