• Episode 312 - Managing the Stress of Weaning: Research Insights for Farmers - UMN Extension's The Moos Room

  This week on The Moos Room, Brad shares updates from the University of Minnesota’s dairy research center, where staff have been on strike and he’s been back in the barn doing chores, milking, feeding, and even pulling calves late at night. With calving season underway, Brad shifts the focus to a new review article on weaning practices in young ruminants, authored by Heather Nave at Purdue University.The discussion explores the stress calves, lambs, goat kids, and beef calves experience when transitioning from milk to solid feed, and how management decisions—such as weaning age and milk removal method—impact long-term health, growth, and welfare. Brad breaks down the pros and cons of abrupt versus gradual weaning, highlights the benefits of later weaning, and shares practical strategies to reduce stress, from nutritional management and water access to social housing and avoiding stacked stressors.Key takeaways include:Later and gradual weaning generally improves growth, gut health, and reduces stress.Early access to palatable solid feed and free-choice water is essential for rumen development.Environmental enrichment and positive human contact can help ease the transition.Veterinarians and farmers should balance short-term economics with long-term animal health and productivity.Tune in for research-backed insights and practical tips to improve calf and herd outcomes during one of the most critical stages of development.Improving the Welfare of Ruminants Around Weaning  in Veterinary Clinics of North America: Food Animal PracticeQuestions, comments, scathing rebuttals? -> [email protected] 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

• Episode 311 - Milk Fatty Acids: The Next Frontier in Dairy Nutrition - UMN Extension's The Moos Room

  In this episode, Brad dives into the growing interest in milk fatty acid profiles and what they can tell us about cow health, nutrition, and management.Brad explains the three main groups of milk fatty acids—de novo, mixed, and preformed—and how they are shaped by diet, stage of lactation, seasonality, and even genetics. He highlights how monitoring these fatty acid trends through routine milk testing can help farmers fine-tune rations, detect health challenges like subclinical ketosis or mastitis, and make more informed feeding decisions.Brad also shares findings from two recent University of Minnesota research projects:Commercial herd study: Comparing Holsteins and crossbreds, as well as feeding strategies (higher starch diets vs. fat supplementation). Results showed small but meaningful differences in fatty acid profiles, with crossbreds showing slightly healthier rumen indicators.University herd study: Comparing organic pasture-based cows to conventional TMR-fed cows, and looking at breed influences (Holsteins, Viking Reds, Jerseys, and Normandy crosses). Pasture cows had higher preformed fatty acids, while Jerseys and Normandy crosses stood out for more favorable fatty acid compositions.The takeaway: fatty acid testing is a valuable management tool for nutrition, genetics, and herd health monitoring—and could even open new opportunities for niche milk markets.Questions, comments, scathing rebuttals? -> [email protected] 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

• Episode 310 -Faster Cows, Faster Parlors: New Genetic Evaluations for Milking Speed - UMN Extension's The Moos Room

  In this Labor Day episode, Brad highlights the history of the holiday in the U.S. and Canada before diving into a brand-new genetic evaluation for Holstein dairy cattle: milking speed. Released in August 2025, this trait provides an objective way to measure how quickly cows milk—expressed in pounds of milk per minute—with the Holstein breed average set at 7 lbs/min.Brad explains how this evaluation was developed using parlor sensor data (not robot milking systems) from over 165 herds and 43,000 cows, making it more accurate than traditional subjective scoring methods used in other breeds. With heritability at 42%, milking speed is a promising selection tool for improving parlor efficiency and labor use.The episode also covers:How milking speed correlates with traits like somatic cell score and mastitis.The range of variation in bulls and what that means for selection decisions.Why milking speed isn’t yet included in the lifetime merit index.Practical implications for farmers considering faster vs. slower milking cows.Brad wraps up by reflecting on how this new tool could impact herd management at the Morris research herd and encourages producers to watch for milking speed in future bull proofs.Questions, comments, scathing rebuttals? -> [email protected] 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

• Episode 309 - From the Fair to the Farm: Dairy Research Updates with Brad - UMN Extension's The Moos Room

  In this episode of The Moos Room, Brad shares updates from a busy summer and fall kickoff at the Minnesota State Fair, where his kids showed cows and he helped with 4-H dairy programming. After reflecting on the fair, he dives into the latest research and extension projects happening at the University of Minnesota’s West Central Research and Outreach Center in Morris.Brad covers a wide range of studies, including:Virtual fencing trials with heifers, lessons learned from training, and future plans to test with milking cows.Horn fly vaccine research, tracking fly counts across hundreds of cows to evaluate effectiveness.Agrovoltaics and portable solar shade, examining how cows use shade structures to reduce heat stress and the impact on pasture regrowth.Parasite monitoring and exploring connections between genetics and parasite load.Heifer feed efficiency, using precision feeders and methane collectors to measure intake, weight gain, and greenhouse gas output.Mastitis management, including trials with alternatives to antibiotics.Genetics-focused projects on inbreeding effects in Holsteins and the potential of polled genetics.Milk processing exploration, with plans to begin producing value-added products like ice cream and butter from the university herd.From innovative technology like virtual fencing to on-farm challenges like mastitis, Brad shares insights into ongoing research aimed at helping dairy farmers improve efficiency, sustainability, and profitability.Questions, comments, scathing rebuttals? -> [email protected] 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

• Episode 308 - Battling BLV – Updates on Bovine Leukosis Virus in the UMN Herd - UMN Extension's The Moos Room

  In this episode of The Moos Room, Brad shares updates on the University of Minnesota’s ongoing work with bovine leukosis virus (BLV), a retrovirus that weakens the immune system, reduces production, and costs dairy farmers hundreds of dollars per cow each year.Brad walks through the latest herd testing results, where prevalence has held steady at around 30%, but with new infections continuing to appear—especially in older cows. He digs into the role of biting flies in BLV transmission, highlighting research showing that nearly all previously negative cows became suspect or positive after just one summer on pasture.The discussion covers:How BLV spreads within herds.The economic and animal health impacts of infection.Management strategies like testing, culling, colostrum protocols, and breeding decisions.Why fly control may be one of the most important tools for reducing BLV spread in grazing herds.Tune in to hear how the UMN Morris dairy herd is tackling this challenge, what the research says about seasonality and transmission, and what steps farmers can take to manage BLV on their own operations.Questions, comments, scathing rebuttals? -> [email protected] 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
