The Moos Room™

Dairy farms generate plenty of data—but turning those records into useful management decisions takes time. In this episode of The Moos Room, Brad explores how artificial intelligence can help organize dairy records, summarize herd performance, and identify priorities for follow-up.Brad shares his experience using Claude AI and open-source dairy data tools to analyze DairyComp 305 exports from the University of Minnesota’s organic and conventional research herds. From milk production and components to fresh cow health, somatic cell counts, and culling, he discusses how AI can bring information together into a practical herd review.He also describes using monthly DHI reports and milk fatty acid profiles to build summaries, graphs, and cow lists that make trends easier to spot.Topics include:Turning DairyComp records into herd summaries and suggested action items.Tracking udder health, fresh cow infections, and milk component trends.Exploring tools for ration formulation, feed costs, and lactation projections.Combining multiple DHI reports into one useful management overview.Recognizing the importance of complete records, data privacy, and checking AI-generated results.The opportunity is making dairy data easier to use. Brad discusses how these tools could support farmers, veterinarians, nutritionists, and Extension educators as they work together to improve herd management.https://dairydatascience.com/https://github.com/padge01/dairy-data-tools/blob/main/README.mdQuestions, 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 

Should you sell a cull dairy cow now or feed her a little longer to improve her market value? In this episode of The Moos Room, Brad explores an economic modeling study examining whether a 60-day feeding program for thin, nonlactating cull cows could improve profitability and animal welfare.Under the modeled conditions, increasing body condition score from 2.0 to 3.0 generated approximately $222 Canadian in additional net returns per cow after accounting for feed, housing, health costs, and mortality risk. Brad discusses why initial body condition, feed costs, and market prices determine whether retaining cows makes financial sense—and why cows already in better condition may offer little opportunity for additional returns.Topics include:Using lactating cow TMR refusals to help control feeding costs.Managing dry-off and transitioning cows to a finishing ration.Selecting physically sound cows without serious health challenges.Accounting for mortality risk and providing adequate housing.Improving body condition and fitness for transportation.The take-home message: Strategic feeding before marketing may add value for selected thin cows, but careful animal selection and farm-specific economics are essential.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 

How does raising calves individually, in groups, or alongside their dams shape their gut microbiome? In this episode of The Moos Room, Brad  discusses a University of Minnesota study examining how these three rearing systems influence microbial communities, growth, and the transition through weaning.Individually housed calves and calves raised in groups of six received similar diets and developed similar gut microbiomes, suggesting that calf-to-calf contact alone had little influence on microbial diversity. Dam-reared calves, however, developed distinct microbial communities and had the highest average daily gains. Their lower microbial diversity before weaning did not correspond with poorer growth.Brad explores how access to milk, contact with adult cows, and exposure to solid feeds may help explain these differences. Within three to four days after weaning, microbial diversity increased in dam-reared calves as they transitioned away from milk, although some differences among rearing systems remained. Because the systems differed in several ways, the findings reflect the combined effects of diet, environment, and maternal contact.The episode also includes updates on fall grazing, virtual fencing, and ongoing calf research at the West Central Research and Outreach Center, plus a preview of Brad’s upcoming trip to Sweden.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 

Are the basics of calf management getting overlooked? Fresh from dairy research meetings in Florida, Brad explores a North American survey led by Penn State’s Melissa Cantor examining the management challenges calf health professionals encounter on dairy farms.Brad discusses how low milk allowances, larger calf groups, inconsistent routines, and poor ventilation can contribute to challenges with respiratory disease, scours, and navel infections. He also shares examples from the University of Minnesota’s dairy herd and explains why troubleshooting calf health requires looking beyond treatments to everyday feeding, housing, and care.Topics include:Milk allowances and the importance of adequate nutrition.Group size, feeding competition, and disease exposure.Written protocols for colostrum feeding, sanitation, and navel care.Clean, dry maternity pens and hygiene at birth.Winter ventilation and timely delivery of adequate colostrum.The take-home message: healthier calves start with consistent management. Before investing in new equipment or changing treatment strategies, review the fundamentals—and make sure everyone caring for calves understands and follows the farm’s protocols.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 

Does a second colostrum feeding give newborn calves an extra boost? In this episode of The Moos Room, Brad explores University of Minnesota research involving 150 dairy and beef-on-dairy calves that examined how a second colostrum meal—and feeding by bottle versus tube—affected immunity, health, appetite, and behavior.On a farm delivering high-quality colostrum within one hour of birth, a second colostrum feeding eight hours later did not significantly increase blood IgG concentrations compared with feeding milk replacer. Brad discusses why that strong first feeding matters when interpreting the results and what the study revealed about second-meal intake, subsequent appetite, and feeding labor. Bottle-fed calves often left part of their meal unfinished, while researchers observed no colic events during the study’s first 72 hours under the feeding protocols evaluated.The practical takeaway: prioritize the timing, quality, and quantity of the first colostrum feeding. Tune in for a discussion of how second feedings fit into calf management, why meal size and spacing matter, and why these findings do not rule out other benefits of continued colostrum or transition milk feeding.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 

Fresh from World Dairy Expo, Brad Heins discusses the newly identified HYAL1 mutation in Holstein cattle and its implications for cow health, longevity, and farm profitability. Research in Switzerland and France links this recessive variant to swollen hocks, joint fluid buildup, impaired mobility, and reduced productive life in cattle that inherit two copies.Brad explains how researchers uncovered a genetic problem that standard additive analyses missed, why joint abnormalities can appear before first calving, and how affected animals may experience lower production and earlier culling. He also explores the importance of combining genomic data with observations of cattle and how genetic testing and avoiding carrier-to-carrier matings could help prevent affected calves. Tune in for a practical look at what this discovery could mean for dairy breeding decisions and healthier, longer-lived cows.The reported 4.4% and 8.4% are allele frequencies, not percentages of affected cattle; and affected animals inherit two copies of the variant. 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 

Virtual fencing is drawing plenty of questions from grazing dairy and beef producers. In this episode of The Moos Room, Brad shares what the University of Minnesota’s West Central Research and Outreach Center learned from using NoFence collars with heifers during the summer grazing season.Undergraduate interns observed 27 heifers from June through August and compared their behavior with collar records of audio warnings and pulses. The heifers spent most of their observed time grazing or standing, although grazing increased as the summer progressed. Observations associated with pulses showed less grazing and more walking, while warnings and pulses varied widely among individual heifers. Brad discusses what those patterns might mean, including how heifers respond when a virtual boundary moves.He also looks ahead to testing additional collars and virtual fencing systems with dairy cattle. Future work will examine animal behavior alongside the labor and economics of managing pasture with virtual fences.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 

Brad begins with an update from the WCROC dairy, where corn silage harvest is complete, fall calving is underway, and new Angus and beef-on-dairy calves are arriving.The episode then examines a six-year study of approximately 1,300 Holstein bull calves purchased through Wisconsin livestock auctions. Researchers measured serum total protein to evaluate whether the calves had received adequate immunity from colostrum. More than 70% of the calves were classified in the poor or fair categories, while only 16% reached the excellent benchmark. Calves with poor passive immunity were nearly 12 times more likely to die than calves with excellent serum total protein levels.Brad discusses why male dairy and beef-on-dairy calves should receive the same high-quality colostrum management as replacement heifers. He also explores how serum total protein testing—using a simple blood sample and refractometer—could help farms evaluate their colostrum programs and give calf buyers better information. Verified colostrum management could reduce calf mortality, reward dairy producers for raising healthier calves, and create greater value throughout the beef-on-dairy supply chain.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 

Early calf socialization may deliver long-term benefitsCan housing calves together during their first weeks of life affect how they perform as cows? This episode examines University of Florida research comparing individually housed, pair-housed and group-housed calves through their first lactation.Socially housed calves grew faster before weaning, producing up to 16% greater average daily gain than individually housed calves. Although differences in growth and reproductive performance largely disappeared after weaning, important benefits emerged after calving. Pair- and group-housed animals produced approximately 1,700 additional pounds of milk during their first lactation and were substantially less likely to be culled.The findings suggest that early social contact builds behavioral resilience. Calves raised with companions may adjust more easily to the milking parlor, regrouping and competition at the feed bunk—helping them maintain intake, manage stress and remain productive during the demanding transition into the milking herd. The results position social housing as more than a calf-welfare practice; it may also be a long-term investment in productivity and herd retention.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 

Can AI turn mountains of dairy data into practical management insights? This episode explores how tools like ChatGPT can analyze bulk tank records, DHI reports, and milking-parlor data. Using examples from conventional and organic herds, we discuss how AI can reveal production and milk-quality trends, identify cows driving somatic cell count, highlight reproductive concerns, and uncover parlor-efficiency problems. AI cannot replace farmers, advisers, or Extension expertise—and its results should always be verified—but it can save hours of spreadsheet work and help dairy managers focus on the issues that need attention. 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
