This episode features Andrea Lendewig, Head of Research & Development at IFCN, discussing her Real Science Exchange webinar presentation Global Dairy Market Status and 2035 Perspectives. Joining the conversation are Philipp Goetz, Head of Sales and Business Development at IFCN; Lucas Fess, Senior Dairy Analyst with Rabobank; and Jeremy Painter, Vice President of Global Commercial Operations for Animal Nutrition & Health at Balchem. Together, the panel examines current milk production trends, regional differences, butter and protein markets, exports, herd dynamics, and what the next decade may hold for global dairy. Andrea opens by outlining IFCN's global dairy data network and explains how annual farm‑level data collection and monthly updates allow IFCN to monitor milk production, prices, and costs across major dairy regions. She highlights a major industry milestone: global milk production surpassing 1 billion tons, driven by growth across multiple regions. (04:40) The discussion then turns to recent production trends. The panel explains how the U.S. has shown consistent strength, while the EU experienced slower growth early before unexpected late‑season increases. China and parts of Latin America continue to grow production but remain dependent on international markets. Weather, animal health, and strong milk prices aligned to create production surprises in several regions. (17:30) Andrea and Lucas examine global milk price dynamics, focusing on the growing divergence between butter and cheese prices over the last decade. Butter prices have increasingly driven global milk price signals, influencing producer behavior and trade flows. One notable shift discussed is the U.S. becoming a net exporter of butter in 2025 after more than a decade as a net importer. (25:10) The panel also explores rising costs of milk production. IFCN data show that milk production costs have increased sharply over the last five years, with roughly 75% of countries now facing costs above $40 per hundredweight. These pressures are influencing farm investment decisions, particularly in regions with stricter environmental regulations. (28:30) Herd dynamics and beef‑on‑dairy economics are another key theme. Lucas and Jeremy describe how record beef prices have reshaped breeding decisions in the U.S., increased calf values, and encouraged producers to keep cows longer. This dynamic has contributed to U.S. herd growth and stronger-than-expected milk supply, raising the question of whether current production trends represent a new normal. (35:00) The conversation contrasts structural differences between Europe, and the U.S. European producers face tighter environmental regulations, land constraints, and aging farmer demographics, limiting expansion. In response, many EU farmers are diversifying income through solar energy, agri‑tourism, and land leasing rather than increasing milk output. Both IFCN and Rabobank suggest 2025 may represent peak milk production for the EU under current conditions. (45:00) Attention then shifts to exports and demand. Lucas outlines where U.S. dairy exports are growing—especially in Mexico, Asia, and emerging markets—and explains why exports will be critical as domestic consumption grows more slowly than production. The panel also discusses rising consumer interest in protein, from high‑protein milk and beverages to whey ingredients, and how this trend supports long‑term dairy demand. (51:00) Looking ahead to 2035, Andrea and Philip share IFCN's long‑term outlook. The U.S. is expected to drive most global production growth, while Europe trends closer to self‑sufficiency and Oceania remains export‑focused. Demand growth—driven by population increases and more westernized diets in Asia, Africa, and the Middle East—is expected to outpace supply growth, supporting higher dairy prices over time. (57:30) In closing, the panel reflects on key takeaways: the importance of data‑driven decisions, diversification of farm income, continued productivity gains through genetics and technology, and strong long‑term fundamentals for dairy. While risks remain, the group agrees the global dairy sector is well positioned for the next decade. (01:02:00) Please subscribe and share with your industry friends.

Dr. Mike Van Amburgh begins by outlining how amino acid nutrition has historically been viewed almost exclusively through the lens of milk protein. He explains that emerging research clearly shows amino acids play far broader roles in the cow, influencing milk fat synthesis, energy metabolism, and overall efficiency. As genetic potential has increased, amino acids are now supporting many biological pathways beyond simple milk protein yield. (05:50) The discussion quickly expands to nitrogen efficiency and environmental sustainability. Dr. Van Amburgh explains that dairy systems across Europe and North America are under increasing pressure to reduce nitrogen losses. By formulating more precise diets that better match amino acid requirements, cows can excrete significantly less urinary nitrogen while maintaining—or even improving—milk production, creating both environmental and economic benefits. (09:30) An audience question shifts the conversation toward the challenge of quantifying amino acids in forages. The panel discusses the robustness of current CNCPS model libraries and explains why forage amino acid profiles tend to be relatively conserved. While management factors like heat damage or poor fermentation can alter availability, microbial protein ultimately supplies a large and consistent portion of metabolizable amino acids to the cow. (12:15) Building on this, the panel explores where required amino acids actually come from. Dr. Van Amburgh emphasizes that microbial protein should supply roughly half of total amino acid needs, making rumen efficiency critical. However, as production levels rise, microbial protein alone is no longer sufficient—creating a clear role for rumen‑protected amino acids to close growing nutritional gaps. (16:20) Dr. Usman Arshad then leads a deep discussion on choline and methionine in transition cows. He explains why these two nutrients are not interchangeable, despite both acting as methyl donors. Choline has a unique lipotropic role in supporting liver fat export and reducing fatty liver risk during early lactation, while methionine primarily supports milk production and protein synthesis. Research shows that choline supplementation during the transition period alone can generate lasting carryover improvements in milk yield later in lactation. (29:00) The panel addresses a common industry question: how much choline is enough? Dr. Arshad reviews decades of research, including meta‑analyses showing a largely linear response between choline ion intake and milk production. While 12–13 g/day of choline ion remains the standard recommendation based on most available studies, data suggest additional benefits may exist at higher levels—even though more research is still needed. (34:00) Attention then turns to amino acid nutrition in close‑up and fresh cows. Dr. Van Amburgh explains that recent infusion and feeding studies demonstrate much higher metabolizable protein requirements than traditionally assumed, driven in part by the important role of non‑essential amino acids. These nutrients support energy generation, glucose synthesis, and tissue metabolism during early lactation—contributing to substantial gains in energy‑corrected milk when requirements are met. (44:30) The panel also discusses whether amino acid balancing can help cows cope with heat stress. While amino acids do not eliminate heat stress, improving metabolic efficiency appears to reduce wasted heat production and support immune function and gut integrity, potentially helping cows better navigate stressful conditions. (54:45) From science to economics, producers raise questions about return on investment. The group shares real‑world examples showing that improving amino acid balance often increases milk components without increasing intake, frequently delivering returns of 2:1 or greater, depending on milk pricing and market structure. (58:00) Dr. Van Amburgh then offers candid insights into rumen‑protected amino acid bioavailability, explaining that products on the market are not created equal. Independent testing has shown efficiencies ranging from as low as ~10% to as high as ~80%. The panel stresses that transparent, published bioavailability data are essential for accurate formulation and for maintaining credibility across the industry. (01:01:30) A technical discussion follows on measuring amino acid bioavailability, comparing isotope dilution, selenium‑methionine, and in vitro approaches. The group agrees that no method is perfect, but understanding assumptions and applying methods consistently can produce reliable, actionable data. (01:06:00) In the final phase of the episode, the panel examines modern high‑starch diets, monensin use, and intake regulation. Dr. Van Amburgh suggests many systems may now be producing excessive propionate, potentially limiting intake through chemical fill. He argues that rebalancing starch and NDF—rather than simply adding more concentrate—may unlock better efficiency and performance. (01:10:00) The episode concludes with final audience questions and a call to rethink traditional nutrition paradigms. The panel emphasizes that precision amino acid nutrition—supported by sound science, verified bioavailability, and thoughtful diet structure—is becoming essential for meeting the production, economic, and environmental demands facing dairy systems today.

Dr. Baumgard opens by explaining the origin of the “immune suppression” theory in transition cows. Research dating back to the late 1970s showed slower neutrophil infiltration into the mammary gland in early lactation, which led to the assumption that cows are immunosuppressed after calving. This idea has shaped industry thinking for more than 40 years. (10:43) He outlines two primary mechanisms traditionally blamed for immune suppression: the cortisol surge at calving, which may impair neutrophil migration, and the metabolic changes of early lactation—high NEFAs, ketones, and low calcium—which appear to reduce neutrophil function in laboratory settings. (13:16) Dr. Baumgard then challenges the central assumption: are cows truly immunosuppressed, or are they simply exposed to greater pathogen loads and stressors during a narrow window around calving? He argues that morbidity may reflect increased environmental and physiological challenges rather than a dysfunctional immune system. (15:25) Dr. Fry shares field data from three herds representing over 100,000 calvings. After implementing management changes—primarily building a well-designed transition barn with lower stocking density, improved hygiene, and better cow flow—metritis rates dropped from 21.3% to 9.7%. Nutrition and innate immunity remained unchanged, suggesting management and environment were key drivers. (21:29) The panel discusses the role of stress stacking during the transition period. Dr. Baumgard explains that multiple simultaneous stressors, such as overcrowding, heat stress, hygiene challenges, social stress, and nutritional shifts, may overwhelm cows. He emphasizes growing evidence that stress compromises gut integrity (“leaky gut”), potentially triggering systemic inflammation and increasing susceptibility in tissues like the mammary gland. (27:27) Heat stress provides another example. While mastitis rates often increase during humid Midwest summers, they decline in arid regions like Arizona and Israel despite severe heat stress. Dr. Baumgard suggests environmental pathogen load—not immune suppression—is the primary driver. (27:43) The conversation shifts to ketosis and hyperketonemia. Dr. Baumgard and Dr. Pralle discuss how elevated BHB and NEFAs may not always indicate disease but instead reflect normal metabolic adaptation to support milk production. The key distinction is productivity: cows milking well with high ketones may not require intervention, while cows with high ketones and poor milk production warrant deeper investigation into underlying causes such as metritis, mastitis, hypocalcemia, gut inflammation, or environmental stress. (37:13) Dr. Fry reinforces the importance of whole-cow and whole-environment evaluation rather than treating metabolic markers in isolation. Monitoring milk yield, rumination, activity, and cow demeanor—along with assessing stocking density, pen hygiene, hoof health, and stockmanship—are critical to identifying true problems. (44:00) The group emphasizes reducing pathogen load through simple, practical management: minimizing manure accumulation, maintaining clean and dry bedding, improving calving hygiene, and lowering stocking density—especially for close-up and fresh cows. (33:39) Looking ahead, Dr. Baumgard describes his lab's focus on modeling “stacked stressors” to better replicate the real-world transition period. Rather than studying stressors in isolation, his team is investigating how combined stressors influence physiology, particularly gut health. (47:11) In closing, the panel encourages industry professionals to reconsider the immune suppression paradigm. Instead of trying to “fix” the immune system at calving, the emphasis should shift toward removing stressors and minimizing environmental challenges that create excessive pathogen exposure.

STgenetics® recently had a study published in the Journal of Dairy Science with the University of California Davis titled “Improving Feed Efficiency With the EcoFeed® Index, reduces Greenhouse Gas Emissions in Dairy Cattle.” Jocelyn Johnson joins us to explain the process behind this study, diving into the multi-year path of building a reference population and publishing/validating genomic evaluations for heifers and cows to demonstrating reduced feed intake without sacrificing productivity and confirming methane benefits. The incredible results from this study indicate a 1 SD EcoFeed® improvement was associated with about $200 in lifetime feed cost savings and just under one ton of reduced carbon per cow. Jocelyn takes these results further and explains how her team is helping producers communicate this message and so much more!

This episode's guests were speakers on the Joint ADSA-CSAS Breeding and Genetics Symposium:Dairy Welfare—Breeding and Management Strategies at the 2025 ADSA annual meeting. Jessica's talk was titled “Herd Sustainability Index: Using milk recording data to evaluate dairy herd sustainability.” This index provides a national percentile ranking benchmark for producers relative to sustainability from DHI data. The index evaluates ten indicators in four major categories: longevity and culling, feeding and production, heifers, and health. (2:51)Dr. Vasseur's talk was titled “Improving welfare through inclusive innovation: The story of WELL-E.” This inclusive innovation delivers data-driven solutions with and for the Canadian dairy industry by integrating stakeholder and domain knowledge with cutting-edge tools and methods of the improvement of animal and human welfare. (4:48)Dr. Vasseur talks about the development of the Code of Practice for the Care and Handling of Dairy Cattle, which was published in 2023. This most recent code of practice included recommendations and requirements for more opportunities for movement for dairy cattle, particularly those in tie stall environments. Dr. Vasseur's lab has conducted research in this area to help dairy producers with possible modifications of stalls and other recommendations to improve cow comfort. Jessica describes her master's research in tie stall modifications. The guests go on to talk about how often cows in tie stalls bump into their stall, some proof-on-concept research looking at doubling stall size, and recommendations for cow comfort improvements in existing tie stall operations. (6:53)Dr. Vasseur discusses the relationship between cow comfort and longevity. She also talks about the realities of converting a tie stall barn to a free stall barn. (20:12)Jessica describes the indicators used in the Herd Sustainability Index in more detail. A minimum of six tests in the last 12 months with 50% of the cows being recorded are needed to calculate the index for a farm. Seven of the ten HSI indicators are required for the index to be calculated. She goes on to explain how producers can see their index compared to the rest of Canada as well as historical change in their index, and details an incentive program for high-indexing and most-improved herds. (24:07)Dr. Vasseur talks about cow comfort and welfare comparisons among intensive dairy production countries. She envisions the development and implementation of technology to allow for more automation and reduced observer bias of processes such as lameness evaluation. (30:30)So what is WELL-E? Dr. Vasseur gives some background and details about bringing together animal scientists, computer scientists, and stakeholders to develop cutting-edge tools for the improvement of animal and human welfare. (33:24)Jessica talks about her PhD research in dairy cow behavior and pasture management. She conducted a study where pastures were mowed the morning of grazing compared to conventional grazing. Cows in the mowed pastures spent more time ruminating and drank more water, but no differences in milk production or milk components were observed. (38:02)Panelists share their take-home thoughts.

AP correspondent Ed Donahue reports on a campus change for cows.

This episode was recorded at the 2025 Western Dairy Management Conference in Reno, Nevada.Dr. Kononoff begins with some renewable fuels history. Since the renewable fuels standard in 2007, corn production for ethanol has increased to around 50% of the crop going to ethanol production. With the subsequent increase in fuel has come an increase in distillers grains and the industry has learned how to use them to feed cattle better. Later, the government created additional policy for next-stage renewable fuels, which has spurred biodiesel production. Currently, just under 50% of the soybean crop goes to fuel production. Soybean meal availability has increased and costs have decreased over the past few years. Most of the soybean oil is solvent-extracted.   (5:57)Dr. Lock talks about increased acres of high-oleic soybeans in dairy-soybean crossover states. He summarizes some of the work his group has done on feeding high-oleic roasted whole soybeans as a replacement for soybean meal in the diet, citing the benefits of the oil in the diet as well as increased bypass protein. (15:41)The panel discusses whether canola meal, which is fairly high in oleic acid, would show similar benefits to feeding whole roasted soybeans. They also talk about how tariffs may or may not impact canola meal and canola oil prices. (24:26)Over time, the dairy industry has moved away from alfalfa as a protein source and toward soybean meal. The panel discusses the pros and cons of this change. (26:46)Dr. Kononoff gives his perspective on just how much soybean meal can be fed in dairy cow diets. Nitrogen excretion is an important consideration. He reminds the audience that renewable fuels policy is the reason behind many of the feed ingredient changes we've observed in the past 15-20 years, and that policy can change very rapidly. He emphasizes the industry needs to remain nimble and prepared to adapt. The panel also touches on pricing of feed ingredients in different parts of the country and how distillers grains are currently used in dairy diets. (31:08)Panelists share their take-home thoughts.

Methane is a potent greenhouse gas that traps energy far more efficiently than carbon dioxide. Reduction of methane emissions is thus essential to slowing climate change, and livestock are a major source of these emissions. Dr. Phil Cardoso talks with Dr. Alex Hristov of Penn State University about nutritional strategies for mitigating production of methane by dairy cattle. They discuss the effectiveness of several different feed additives at reducing methane emissions and their effects on DMI and milk production.Links to papers and other sources mentioned in this episodeHristov et al. 2022.

Amid rising concerns about bird flu affecting dairy cows, experts want the public to know one thing clearly: pasteurized milk is safe. Dr. Keith Poulsen, Director of the Wisconsin Veterinary Diagnostic Laboratory, emphasized, “Pasteurization is 100% effective. This is not a food safety issue.” He also shared reassuring news: no bird flu virus has been found in Wisconsin dairy cows to date. While poultry have been hit hard by the H5N1 virus, dairy cows experience it very differently. “We’re not seeing cows die from this virus,” Dr. Poulsen said. “Only about 2 to 3 percent of cows are affected, and most recover.”See omnystudio.com/listener for privacy information.

The work continues to prevent the highly pathogenic avian influenza from disrupting dairy herds. Several states have had the virus infiltrate dairies, but Wisconsin is not one of them. The goal of state health officials is to keep it that way. Dr. Heather Roney is a veterinarian and epidemiologist with the state Department of Agriculture, Trade and Consumer Protection's Division of Animal Health, overseeing state cattle programs. She says Wisconsin's dairy industry is different from the other top dairy-producing states that have struggled with the virus -- we're not bringing in a lot of lactating cows. This benefits our dairy industry in preventing the spread of HPAI/H5N1. Wisconsin is currently under two federal orders and one state order regarding lactating dairy cattle testing. Roney says even dairy farmers who are not required to test their milk are volunteering to test and being proactive.See omnystudio.com/listener for privacy information.

This episode was recorded at the 2025 Florida Ruminant Nutrition Symposium. Dr. DeVries' research focuses on farm-level decisions and modeling. The University of Florida dairy has implemented the use of beef semen. Dr. DeVries describes some of the factors that go into a partial budget for this system as well as details some of the factors involved in implementing beef on dairy. The UF dairy genomically tests all their cows and the panel discusses some differences in beef and dairy selection based on genomics. (5:58)Dr. Felix asks how the beef sires are selected for the UF dairy. Calving ease and fertility are key, as well as low cost. Dr. Johnson asks if spending a little more on beef semen might pay off in the longer term regarding beef quality. The panel agrees that in the current market, dairy producers are getting $800-$1000 for a day-old calf regardless of the beef sire, so perhaps beef sire selection has not been a major focus. (15:07)Dr. DeVries describes some of the data he evaluates when deciding how many cows to breed with sexed dairy semen. Given the current beef prices, heifer retention has not been as high in either the beef or dairy sector as previously predicted. (19:22)The panel discusses the importance of cow longevity in the dairy sector. Dr. DeVries explains the pros and cons of keeping cows in the milking herd longer. Dr. Nelson reminds listeners of the current cull cow market and how that also plays a role in decision-making for dairy and beef producers. (24:16)Dr. Nelson describes the heifer development program for the UF dairy. Week-old heifer calves are shipped to Kansas for development and return to UF at about 200-220 days pregnant. This approach is very common in the southeast. Many of the beef on dairy calves will also be shipped to calf ranches out of state. (30:59)Dr. DeVries' model concluded that switching from conventional dairy to beef-on-dairy resulted in about $150 advantage per cow per year. On top of that was another $50 per cow because of the switch to sourcing your heifers from your best cows. (34:13)The panel discusses the idea of transferring beef embryos into dairy cows. Could there be a day when this approach creates beef calves less expensively than the cow/calf sector can? They also delve into whether there will be any long-term negative impacts of breeding dairy cows with beef semen. (38:44)Dr. Johnson mentions another paradigm shift of the beef-on-dairy system is feeding dairy-influenced heifers in the feedlot, which has not happened before. Technologies used to promote growth in the feed yard can induce spontaneous lactation in some of these heifers. Milk is considered an adulterant in the packing plant and requires trimming if it splashes on a carcass. Dr. Nelson suggests that until there is a discount for heifer beef on dairy calves, there won't be a shift to using sexed male semen to create predominantly beef on dairy steers. (48:33)The panel wraps up with their take-home thoughts.

This episode was recorded at the 2025 Florida Ruminant Nutrition Symposium. Dr. Johnson and Dr. Felix begin with brief descriptions of their background. (1:26)Dr. Johnson's presentation at the symposium focuses on beef quality aspects of using beef sires on dairy cows. Using the same Angus semen, his research model compared Angus-sired beef calves raised in a conventional cow-calf system, Angus x Holstein calves, Angus x Jersey calves, and Angus-sired IVF beef embryos transplanted into Holstein and Jersey cows. The model evaluated how the management impacted feedlot performance and carcass quality. (6:37)Dairy-influenced beef is tender and highly marbled. It also has more oxidative fibers prone to lipid peroxidation and higher myoglobin content which gives it a redder hue. When high-myoglobin beef is in retail packaging, it goes through discoloration faster than traditional native beef, and retailers shy away from that. Beef on dairy products have a retail display life more like native beef, and large retailers are embracing that product. (10:12)Ribeye size was not different among any of the cattle groups in Dr. Johnson's study, including straight calf-fed Holsteins. Beef on dairy calves have similar ribeye area and 0.15-0.20 inches less backfat than a straight beef calf, so their yield grades are lower, implying more red meat yield. In practice, however, they don't have increased red meat yield compared to native beef because they give up so much muscle in their hindquarter. (14:14)Dr. Felix asks if the selection criteria of the Angus sire Dr. Johnson used may have limited the findings from a yield standpoint. Dr. Johnson agrees that was definitely the case, as they chose a high-marbling sire on purpose, and he happened to be fairly light muscled. Dr. Johnson feels that improving the plane of nutrition of beef on dairy calves in the hutch for the first 60-70 days could vastly improve hindquarter muscling later in life. (19:39)Muscle biopsies from the ribeye and hindquarter of hutch calves on low and high planes of nutrition found no difference in muscle proliferation in the ribeye. Hindquarter muscle proliferation was improved in calves on the high plane diet. Dr. Felix reiterated that there is a lack of literature in this area. (25:35)If beef on dairy calves have less backfat, does that mean they have better feed efficiency? In Dr. Johnson's study, the best feed efficiency group was the Angus x Holstein F1 cross. Dr. Felix and Dr. Johnson discuss changes in feedlot practices and days on feed and how the industry is moving to carcass-adjusted average daily gain and feed efficiency measures. (31:14)The panelists discussed the impact of gut size on carcass value. In the dairy industry, we want cows to have high intakes for high milk production, which requires a large gut size. Dams of beef on dairy calves may pass on these traits. Dr. Johnson describes a beef calf and a beef on dairy calf out of the same sire where the beef calf was 40 pounds lighter at the end of the feeding period, yet both calves had the same hot carcass weight. That 40-pound difference was gut size. Dr. Felix and Dr. Johnson share their experiences with differences in fat and trim between beef and beef on dairy carcasses. (39:25)Dr. Felix asks Dr. Johnson how the valuation of beef on dairy calves drives marketing decisions. Day-old dairy calves are extremely valuable right now. A high index beef on dairy calf will bring $800-$1100, depending on what part of the country you live in. If a dairy producer only has $200 in that calf, they should take the money and run. There is no way they will make $800 per head feeding out those calves. (47:30)In closing, Dr. Zimmerman urges ASAS and ADSA to bring back Joint Annual Meetings so more cross-species interactions can be fostered. Dr. Felix notes there is a tremendous gap where the dairy nutrient requirements end and where the beef nutrient requirements pick up. We need to fill that gap to better target optimal muscle development in beef on dairy calves. Dr. Johnson is enthusiastic about the amount of progress the beef on dairy sector has experienced in a short period. We're one or two tweaks away from beef on dairy carcasses rivaling native beef in quality. What we're learning in this sector can also be applied to the native beef sector to improve meat quality and red meat yield.

This Real Science Exchange podcast episode was recorded during a webinar from Balchem's Real Science Lecture Series. You can find it at balchem.com/realscience.Dr. Baumgard begins with an overview of the structure and function of the gastrointestinal tract. More than 75% of an animal's immune system resides in the gut. The focus of this webinar is how heat stress initiates leaky gut, how that leaky gut then influences the immune and hormonal systems, and ultimately, how that reduces productivity. (0:22)Dr. Baumgard compares the metabolism of a cow 200 days in milk to a cow 10 days in milk. The 200-day cow is experiencing ad libitum intake and gaining weight. Her insulin levels would be high, and NEFAs would be low. On the other hand, the 10-day cow is experiencing suboptimal intake, and her insulin levels are the lowest they'll ever be during the production cycle. Body tissue is mobilized, and NEFAs will increase. Research shows it takes 72 grams of glucose to make one kilogram of milk. Any disruption to the gluconeogenic pathway has the potential to decrease milk yield. (6:38)Heat stress is estimated to cost the US dairy industry $1.7 billion each year. Regardless of climate change, heat stress will continue to be an issue because all economically important phenotypes in animal agriculture are heat-producing processes. Dr. Baumgard's lab has been investigating the biology of heat stress to implement more effective mitigation strategies. (9:09)How much of the reduction in feed intake during heat stress explains the reduction in milk yield? A pair-feeding experiment comparing thermoneutral to heat-stressed cows showed that about 50% of the reduction in milk yield during a heat wave is due to a reduction in feed intake. The thermoneutral cows lost weight in response to decreased intake, and their NEFAs increased. Heat-stressed cows did not have an increase in NEFA. Heat-stressed animals fail to mobilize adipose tissue despite their endocrine profile predicting that they should. However, insulin is high when we would expect it to be low, and that response to heat stress is highly conserved in all species. (10:43)Heat-stressed cows produced about 400 grams less lactose per day than their pair-fed thermoneutral controls. This is nearly a pound! Is the liver producing 400 fewer grams of glucose each day? Or is some other extramammary tissue using more glucose per day? Dr. Baumgard's work suggests that the immune system is where the 400 grams of glucose go in heat-stressed animals. During heat stress, vasodilation at the body surface occurs, with concomitant vasoconstriction in the gut. The gut epithelium is very sensitive to reduced oxygen delivery that would result from the vasoconstriction, and tight junction proteins do not function properly, resulting in a leaky gut. This results in an infiltration of antigens into the body, which causes an immune response.  (15:36)Dr. Baumgard details how insulin fits into these immune responses via the Warburg effect. An activated immune cell prefers glucose and needs it in high quantities. The activated cell switches from the Kreb's cycle to generate ATP to aerobic glycolysis. This requires high insulin. The immune system requires approximately one gram of glucose per kilogram of metabolic body weight per hour. (25:03)By far, the biggest impact a dairy producer can make to alleviate heat stress is to modify the environment physically: shade, fans, soakers, misters, etc. Investing in cooling cows improves production efficiency and profitability, summer fertility, animal welfare and health, and sustainability. Other important heat abatement considerations include adequate water availability, reducing walking distance to the parlor and time in the holding pen, and improving ventilation. Dry cows should also be part of any heat abatement strategy, as the benefits of cooling dry cows extends far into lactation. Dr. Baumgard also discusses different dietary management strategies for heat stress situations. (32:43)In summary, heat stress decreases almost every metric of productivity and costs everyone in the industry. Reduced feed intake is only part of the problem. Heat-induced leaky gut results in biological consequences incredibly similar to any other immune activation, such as mastitis or metritis. For dairy producers, heat stress abatement should by far be their biggest priority. Once those infrastructure improvements are in place, dietary interventions are another good strategy to minimize the negative consequences of heat stress.

A new year brings new questions and more insights to the topic of Highly Pathogenic Avian Influenza. Dr. Mike Brasher is joined by leading experts in the field of avian influenza, Dr. Dave Stallknecht, Dr. Richard Webby, and Dr. Jennifer Ballard to discuss the current status of avian influenza, what we've learned since 2022, and what we still don't understand. Recent changes have been noted in the genetic code of the circulating virus, but what does this mean for the risk it poses to birds, mammals, and humans? How do we study these changes? What waterfowl species are most affected, and do we understand why these effects differ among species? Also discussed is recent science about risks to hunting dogs, what hunters need to do if they observe sick or dead birds, why hunters should be vigilant about being tested for avian flu if they feel ill, and how we can all work to reduce the likelihood of the virus becoming more severe. Tune in for an information-packed episode that is of growing relevance to everyone.Listen now: www.ducks.org/DUPodcastSend feedback: DUPodcast@ducks.org

AABP Executive Director Dr. Fred Gingrich is joined by AABP members Dr. Pat Gorden and Dr. Keith Poulsen to provide a situational update on the Highly Pathogenic Avian Influenza H5N1 disease outbreak in dairy cattle.  This podcast is sponsored by Boehringer Ingelheim 3600 coverage. Every lactation cycle, cows are up against the threat of mastitis. Which really means you're up against it, too. Thankfully, Boehringer Ingelheim has you covered with 360° coverage solutions. From prevention to treatment options designed for judicious antibiotic use, the 360° coverage mastitis portfolio has the products you need to defend udders at every angle. What's in your cattle health toolkit? For more information, visit this link. We discuss a wide range of topics, including how this virus jumped from birds to cows and has since spread to over 500 dairy farms in the U.S. via cow-to-cow transmission and fomite spread from dairy-to-dairy and dairy to poultry. Our guests discuss the importance of biosecurity, national surveillance and vaccination to eliminate this virus from the U.S. dairy herd. We discuss diagnostic surveillance and the importance of getting all farms to participate in surveillance to identify positive herds and prevent further transmission. The bulk tank PCR test will be positive two weeks before the herd shows clinical signs, providing an opportunity for dairy farmers and veterinarian prepare as well as implement biosecurity practices to protect other premises in their area. Our guests also discuss the work of AABP, in collaboration with other stakeholder groups, to provide advocacy, guidance and resources to our members. Organized veterinary medicine plays a critical role in a disease outbreak and we encourage all cattle veterinarians to join AABP to help us in our efforts. Links:Join AABP or pay dues at this link. AABP H5N1 resources page.USDA confirmed cases dashboard page.    

Hello there!In this episode of The Dairy Podcast Show, Dr. Rebecca Meagher from Dalhousie University discusses the intricacies of animal welfare, focusing on dairy cattle. Dr. Meagher explores practical ways to enhance natural behaviors, reduce stress, and improve the well-being of dairy herds. Tune in now, available on all major platforms."We can't ask animals directly what they feel, but we can tell a lot from their behavior. By offering choices, we can understand their positive or negative experiences."Meet the guest: Dr. Rebecca Meagher is an Associate Professor in Animal Welfare at Dalhousie University. With a BSc in Zoology from the University of Toronto and a Ph.D. in Animal Science from the University of Guelph, Dr. Meagher focuses on how housing and management affect the welfare and behavior of captive animals, particularly dairy cattle and farmed mink. Her research explores the impact of social environments and environmental enrichment on stress, cognition, and productivity, with a special focus on early-life management. What you'll learn:(00:00) Highlight(00:51) Introduction(02:51) Measuring welfare(04:55) Defining natural behavior(09:51) Social contact in calves(11:29) Enriching dairy environments(16:26) Benefits of animal welfare(24:07) Final three questionsThe Dairy Podcast Show is trusted and supported by innovative companies like:* Adisseo- ICC- Diamond V- Volac- SmaXtec- Acepsis- Trouw Nutrition- Protekta- Natural Biologics- dsm-firmenich- Berg + Schmidt

Dr. Kononoff's lab evaluated retrospective feed mixing records collected from eight commercial dairy farms. Data was divided into 28-day periods. Daily TMR nutrient deviation was automatically calculated from feed mixer data as the actual amount of a nutrient fed minus the target amount from the original diet formulation, divided by the target amount. (5:43)Crude protein, NDF, fat, and starch were the nutrients evaluated in the study. (13:40)Variation was positive for every nutrient on the vast majority of days. Dr. Kononoff attributes that to more feed being delivered than the diet formulation predicted animals would consume. Dry matter intake decreased with increasing positive deviation days in starch and increased with increasing positive deviation days in crude protein. NDF deviation did not impact dry matter intake. A narrow range of diets was used in the dataset and the main byproduct feed was high in NDF, so Dr. Kononoff speculates that there was not a wide enough range in NDF to have an impact on intakes. (17:04)Milk yield increased with increased positive deviation days in starch and decreased with increased positive deviation days in NDF. The pregnancy rate increased with increasing positive deviation days in fat and decreased with increasing positive deviation days in crude protein. Unfortunately, milk urea nitrogen data was not available in the dataset to further investigate the crude protein/pregnancy rate relationship. (20:44)There was little farm-to-farm variation in the data. (25:08)As positive deviation days for starch increased, so did feed conversion. The opposite effect was noted for NDF. As positive deviation days for fat increased, feed conversion decreased. This result was a little surprising, as delivering more energy usually improves feed conversion. However, the dataset did not specify the source of fat or fatty acid profile, so there may have been some rumen fermentation interference from fat. (27:08)Dr. Kononoff thinks it would be interesting to track individual cows through lactation and collect nutrient variation data. Dr. Weiss asks if the correlation between daily farm milk yield and nutrient variation was evaluated; it was not. Dr. Kononoff agrees that there may be some additional correlations that would be interesting to run. (33:22)In closing, Dr. Zimmerman commends Dr. Kononoff's work in tackling such a large dataset and looks forward to follow-up research. Dr. Weiss agrees and encourages more data extraction from the dataset. He was also very surprised at the low farm-to-farm variation observed and speculated if that would hold up if there were more variation in diets. Dr. Kononoff reminds the audience that taking a look at the TMR beyond the paper ration and digging into mixing techniques and TMR consistency is as important as evaluating bulk tank information or the amount of milk shipped.
