Podcasts about dairy cattle

Research is being done to breed a dairy-beef hybrid for meat consumption.

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.

Noelle Fox was nominated as a Beck's Player with Heart for her commitment and passion on and off the court. What she loves most about high school sports is the friendships and relationships she has built with her teammates. The bond formed through countless hours of practice, long bus rides, and tough games is something truly special. As a senior, Noelle has especially enjoyed mentoring younger players and being a support system for them, whether it's offering words of encouragement, a quick hug, or even a prayer when they need it. She has also taken pride in being a positive role model for the team managers, making sure they feel just as valued as the players on the court. Beyond the relationships, high school sports have taught her the importance of time management. Balancing late-night games and the demands of College Credit Plus classes has challenged her to stay organized and disciplined. Throughout high school, Noelle has been actively involved in academics, athletics, and leadership opportunities that have shaped her character and work ethic. She has been a member of the basketball and volleyball teams for all four years. Outside of sports, she is involved in FCCLA and Fellowship of Christian Athletes, is currently serving as an FFA Officer, helps as a Student Advisor, and has earned her Chapter and Greenhand Degrees. Additionally, she anticipates earning her State FFA Degree in May. She has competed in Dairy Cattle and General Livestock Career Development Events (CDEs). Noelle also participates in her church youth group. This summer, she will also be attending a mission trip to the Dominican Republic.

Highly pathogenic avian influenza (HPAI) is a contagious viral disease that continues to impact domestic and wild birds. In March of 2024, HPAI was detected in dairy cattle in Texas, has since spread rapidly across the United States. In this new miniseries, Dr. Murray Gillies, the Coordinator for the Canadian Animal Health Surveillance System, and Dr. Henry Ceelan, a bovine veterinarian and Secretary Treasurer for the Canadian Association of Bovine Veterinarians, join Dr. Steven Roache of ACER Consulting to discuss HPAI in dairy cattle, including disease presentation, spread, and prevention, as well as the Canadian response.   Links of interest CFIA: Highly pathogenic avian influenza (HPAI) in cattle USDA: HPAI in livestock Dairy Farmers of Canada and Animal Health Canada: HPAI: Biosecurity Recommendations for Dairy Farmers National Collaborating Centre for Environmental Health: Avian influenza A(H5N1) in dairy farms: An update on public health and food safety concerns

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.

Aspirin has never gone through the process of being approved by the Food and Drug Administration (FDA) for use in cattle. However, FDA considered aspirin to be of “low regulatory concern,” so its use in scenarios where a veterinarian determined there to be no other option for treatment was acceptable. The agency has now reversed that stance and released a letter to veterinarians emphasizing that aspirin use in dairy cattle and other food animals is prohibited.

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.

This episode comes to you from the 2024 Tri-State Dairy Nutrition Conference, where Balchem sponsored a Real Science symposium titled “New Discussions in Amino Acid Nutrition.” Each of our guests presented at the symposium, and their presentations can be found at balchem.com/realsciencemediaDr. Van Amburgh presented “Amino Acid Nutrition for Maximizing Milk Component Yield.” When considering nitrogen efficiency, we generally compare intake nitrogen, which includes non-protein nitrogen, against milk nitrogen. In high producing cows, aggregate amino acid values are running about 70 to 73% efficiency. But when we work that up to total intake nitrogen, then we're down to 30 to 35% efficiency range. How do we reconcile ruminal nitrogen requirements to a point where we can optimize the capture of recycled nitrogen and reduce the amount of nitrogen that's being excreted in the urine? (2:27)Dr. Hanigan presented “Understanding Amino Acid Bioavailability.” Our current methods for measuring bioavailability don't all have the same precision. One of the classic methods, intestinal disappearance, has very low precision. Methods that rely on dilution of a marker or a label in blood or milk have much higher precision. Dr. Hanigan's lab has worked to modify a carbon-13 labeled amino acid method to allow for evaluating changes in the supply of amino acids in the diet.  (5:01)Dr. Lee presented “Current Understandings of Lysine Nutrition in Dairy Cattle.” Rumen-protected lysine has more variable responses than rumen-protected methionine or histidine. Amino acid requirements were developed based on the role of amino acids as the building blocks of protein. But there are many roles of amino acids which may influence their requirements. Dr. Lee suggests including that type of information in our modeling may increase the consistency of responses to feeding rumen-protected lysine. (11:24)Dr. Hristov presented “Histidine: A Limiting Amino Acid for Dairy Cows.” His group has worked with rumen-protected histidine to develop a dataset to define requirements. Microbial protein has considerably less histidine than methionine yet they are secreted at about the same level in milk and are metabolized similarly. All this together points to a higher histidine requirement. (18:02)The panelists agree that the advent of genomics have resulted in a rapid change in high producing cows and with that, their amino acid requirements (and other nutrients) are also changing. It's a challenge for feeding and nutrition programs to keep up with rapid genetic change. (21:02)A question was posed by the audience about how Dr. Van Amburgh used amino acids to increase butter fat. In the research he presented, the diets did not overfeed fat and fed a blend of fatty acids, and also increased the sugar and pulled back the starch. (28:35)A discussion of histidine follows, including its unique body reserves, its role in hemoglobin concentrations, and its potential impacts on metabolic energy efficiency (34:08)Dr. Zimmerman asks about plasma histidine in very early lactation cows. Dr. Hristov is currently conducting a fresh cow experiment to assess this. His hypothesis is that because of low dry matter intake and high metabolic demand for amino acids, there will be a response to histidine supplementation. Dr. Lee agrees and feels that the fresh cow stage may be one of the most practical ways we can utilize rumen-protected histidine (39:39)A question from the audience about the use of blood meal in lower protein diets sparks a spirited discussion among the panelists. (41:55)In closing, each panelist provides a takeaway. Responses range from bioavailability of rumen-protected products to challenges to progress for ruminant amino acid research to comparing biological potential and economic response.
