The Moos Room™

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.

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? -> [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 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? -> [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 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? -> [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 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? -> [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

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? -> [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

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? -> [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

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? -> [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 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? -> [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

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? -> [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

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? -> [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

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? -> [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

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? -> [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
