  • Episode 325 - Calf Transport: Why Early-Life Management Matters More Than Miles - UMN Extension's The Moos Room
    Dec 15 2025

    In this episode of The Moos Room, Brad dives into a landmark new study examining the effects of short- and long-distance transport on the health, survival, and growth of pre-weaned dairy and dairy–beef crossbred calves. Drawing on data from nearly 392,000 calves across multiple farms and transport durations (ranging from 30 minutes to 24 hours), the study challenges common assumptions about calf transport. Surprisingly, mortality upon arrival was extremely low and unaffected by transport length. Differences in mortality by weaning (60 days) were also modest and, importantly, were driven far more by early-life factors than by time spent on the truck.

    The discussion highlights colostrum management as the single most critical factor influencing calf outcomes. Calves fed two colostrum meals had higher serum protein levels, significantly lower rates of failure of passive transfer, and were about 50% less likely to develop diarrhea—one of the leading causes of pre-weaning mortality. Other key drivers of calf survival included diarrhea, pneumonia, dam parity, gestation length, and birth season, with transport duration explaining relatively little of the variation in outcomes. Brad emphasizes that a calf’s “destiny is largely sealed before the wheels start rolling,” underscoring that management decisions made at birth—especially colostrum feeding, dam health, and environmental stress mitigation—matter far more than transport distance alone.

  • Episode 324 - A New Vet in Town: Dr. Angie Joins the Moos Crew - UMN Extension's The Moos Room
    Dec 8 2025

    In this episode, Brad and Emily welcome a special guest: Dr. Angie Varnum, the University of Minnesota Extension’s new livestock veterinarian. After some banter about Minnesota winters—and a classic round of The Moos Room’s “super-secret” cattle breed questions—the crew dives into Angie’s unique path to Extension.

    Angie shares how she went from growing up in suburban Maple Grove to studying Spanish education, teaching in schools, and eventually being inspired to pursue veterinary medicine. Her training and work took her across the western U.S., where she gained experience in beef and dairy systems before returning to Minnesota to practice large-animal medicine. Her love for both animals and education ultimately led her to Extension.

    The conversation explores:

    • How Angie’s Spanish language background shapes her work and the opportunities it creates for better outreach and training with Spanish-speaking livestock employees.
    • Current and emerging livestock health concerns, and the importance of distinguishing real risks from media frenzy—while still preparing producers with good information.
    • The evolving role of veterinarians in dairy and beef systems, from herd health and data-driven decision-making to the value of strong producer–vet relationships.
    • Animal behavior and welfare science, an area Angie is especially passionate about integrating into herd health discussions.

    Angie also highlights upcoming Extension programs she’ll be involved in, including the new Artificial Insemination School, Beef Quality Assurance certification sessions, Cow/Calf Days, and several small ruminant programs—from webinars to hands-on lambing and kidding workshops.

    It's a fun, thoughtful conversation introducing a new member of the Extension livestock team and setting the stage for exciting work ahead.

  • Episode 323 - Why Aren’t The Cows Milking in Our Herd? A Deep Dive Into Dairy Nutrition Troubleshooting - UMN Extension's The Moos Room
    Dec 1 2025

    In this solo episode of The Moos Room, Brad dives into a deep, honest look at production challenges in the University of Minnesota dairy herd and the nutrition and management factors that may be holding cows back. After noticing low udder fill during classification and reviewing herd data, Brad confirms a troubling trend: cows across all lactations are producing 20–30% less milk than predicted. Early-lactation health issues—ketosis, metritis, and retained placentas—are also more common than they should be, especially in first-lactation animals.

    A recent visit from an outside nutrition team helped uncover several key issues contributing to poor performance. Brad walks listeners through what those “fresh eyes” found across young stock, calves, dry cows, and both the organic and conventional lactating herds. From overconditioned heifers to transition problems at weaning, ration inconsistencies, possible ingredient imbalances, and major concerns with hammer-mill screen size causing undigested corn to pass straight through cows—each discovery points to opportunities for improvement.

    The conversation also highlights the importance of forage management, including the need for a silage facer, better bunk management, and a long-overdue TMR audit to evaluate mixing order, load prep, refusals, shrink, and ration consistency.

    Throughout the episode, Brad emphasizes transparency and the value of bringing in additional perspectives. Even well-managed dairies can develop blind spots, and small issues add up fast when milk is left on the table. He outlines the farm’s next steps and promises future updates as changes are implemented.

    If you’re interested in nutrition, transition cow health, TMR audits, or practical herd-level troubleshooting, this episode is a real-world case study in identifying problems and planning for better performance.

  • Episode 322 - Understanding Farmer Stress: What to Watch For and How to Help - UMN Extension's The Moos Room
    Nov 24 2025

    Brad and Emily reunite on the podcast to dive into an essential—and timely—topic: farmer mental health. With fall wrapping up and winter on the horizon, stressors on the farm shift and often intensify. Emily shares updates on her recent travels and outreach work in farm safety, health, and wellness, highlighting the seasonal rise in mental health–related concerns across rural communities.

    Together, Brad and Emily walk through:

    • Why stress is so high right now — uncertainty in markets, weather, disease, economic pressure, and social isolation.
    • Common mental health concerns in farmers, including chronic stress, anxiety, and depression.
    • Key warning signs to watch for in yourself and others—physical symptoms, behavioral changes, and emotional red flags.
    • How to reach out when you're concerned about someone, and why it matters more than people realize.
    • Barriers rural residents face when accessing mental health care, including service shortages and stigma.
    • University of Minnesota Extension’s work supporting mental health, including training programs like COMET, resources on ambiguous loss, and broader regional efforts to make help more accessible.

    Emily emphasizes that checking in, offering support, and connecting people to resources can make a meaningful difference. The episode wraps with reminders that it’s okay to not be okay—but it’s not okay to keep it to yourself. Brad and Emily also point listeners to a long list of mental health and farm stress resources in the show notes, including Emily’s recent appearance on RFD-TV discussing this very topic.

  • Episode 321 - Timers, Tech, and Jerseys: A South Dakota Dairy Roadtrip Deep Dive - UMN Extension's The Moos Room
    Nov 17 2025

    Brad recaps a fall road trip with the Minnesota dairy extension team to South Dakota’s rapidly growing I-29 dairy corridor, highlighting what innovative farms are doing to boost efficiency, cow health, and profitability. Along the way, they tour the Bel Brands plant in Brookings, where milk from about 10,000 cows a day is turned into those familiar Babybel snack cheeses, and hear how the plant’s demand for high-protein milk is shaping local production.

    On the farm visits, Brad digs into why one 1,700-cow dairy is ripping out a barn full of robots after just a few years—citing software headaches, maintenance demands, and an extra dollar per hundredweight in cost—and how they’re using strict 5-minute milking times and strong beef-on-dairy markets to stay competitive. He then visits a Holstein dairy using parlor timers, FutureCow brushes, genomic testing, Akushi (red Wagyu) beef-on-dairy crosses, intensive calf biosecurity, and a Danish SKOV ventilation system to keep big groups of calves healthy.

    The final stop is a 6,000-cow Jersey herd proving Jerseys can be successfully raised in northern climates. Brad shares how they use SenseHub tags on calves from birth, IVF and embryo work for high-value Jersey genetics, fresh-heifer mastitis prevention strategies in recycled bedding systems, and clever pen redesigns to add bunk space.


    In this episode, you’ll hear about:

    • Why one large dairy abandoned milking robots for a parlor
    • How timers in the parlor are being used to speed up milking and labor efficiency
    • Beef-on-dairy strategies, from Angus to Akushi crosses and premium Texas markets
    • New approaches to calf housing, ventilation, and biosecurity
    • Using precision technology and genomic data to guide breeding and health decisions
    • Practical ideas Brad wants to bring home to the U of M dairy, from boot disinfectant to fresh-heifer dry treatment

  • Episode 320 - Robots, Crossbreeding, and Straw — A Moos Room Travel Report from Europe - UMN Extension's The Moos Room
    Nov 10 2025

    Brad recaps his trip to dairy farms in the Netherlands and Germany, where robotics, crossbreeding, and creative manure and energy management are everywhere — even on small farms. He visited farms using Lely robots, grass/rye silage-based diets, and small-scale digesters that capture manure methane. Crossbreeding (Holstein × Montbéliarde × Viking Red) is common, driven by goals of longevity, health, and reducing inbreeding.

    He also saw some surprising management choices: dry cows fed only straw for 60 days (reportedly reducing metabolic issues) and one advisor recommending farmers don’t clean calf pens to preserve the microbiome — a concept Brad remains skeptical about.

    At a dairy technology show and breeding conference, Brad shared research on feed efficiency and methane emissions and learned how European breeders are incorporating resilience and efficiency traits into genetic programs. Overall, Europe’s dairy farms showed strong use of technology, a focus on components and longevity, and serious interest in crossbreeding as a labor- and health-saving strategy.

  • Episode 319 - Inbreeding: Is It An Impending Doom? - UMN Extension's The Moos Room
    Nov 3 2025

    In this episode, Brad is back from Europe—jetlagged but full of insights from farms and conferences in Germany and the Netherlands. He dives into one of the biggest topics he heard about abroad and at home: Inbreeding in dairy cattle.

    Brad explains how inbreeding occurs, what it costs farmers economically, and how inbreeding levels have climbed across all major dairy breeds—especially Holsteins and Jerseys. Drawing on recent research from Italy and data from the U.S. Council on Dairy Cattle Breeding, he outlines how increasing inbreeding negatively impacts cow survival, fertility, and long-term profitability.

    The discussion highlights startling trends—Holstein inbreeding has jumped from 3.7% in the mid-1990s to nearly 11% today, and some genomic bulls now exceed 16%. Brad also touches on historic bulls whose genetics still dominate today’s herds, like Elevation and Highland Magic Duncan, and explores whether approaches like crossbreeding, linebreeding, or greater genetic diversity in breeding programs could help slow the trend.

    Brad concludes with a call to action: farmers, AI companies, and breed associations must prioritize genetic diversity now to safeguard herd health and productivity.

  • Episode 318 - Cattle, Shade & Solar: What Agrivoltaics Really Looks Like (with Anna Clare) - UMN Extension's The Moos Room
    Oct 27 2025

    Brad kicks off a solo episode (recorded before a trip to Germany) and turns the mic to rangeland scientist Anna Clare for a deep dive into “the solar savanna”—treating solar arrays on grasslands as functioning grazing ecosystems. She shares early results from Silicon Ranch’s Cattle Tracker research on integrating cattle (not just sheep) with PV systems. Brad follows with University of Minnesota’s on-farm demos: panel heights that work for cattle, heat-stress reductions, forage performance under panels, and a mobile, battery-equipped shade/solar rig. If you’re curious how and when cattle can safely graze under solar, this one’s packed with data and practical design tips.

    Key takeaways

    • Solar as savanna: Think of arrays as shade “canopies” over grasslands—manage them as grazing systems with soils, roots, pollinators, and large herbivores in mind.
    • Cattle can work under PV: Moving from sheep to cattle is feasible when arrays are designed with animal size/behavior in mind.
    • Panel height matters: In controlled mockups, animal interactions dropped 43% from 2.0→2.5 m and 59% at 3.0 m. Cattle never touched panels; most curiosity was with dampers—a design hotspot.
    • Ecosystem wins: Under-panel zones showed higher soil moisture and lower soil temperatures, favoring cool-season grasses and legumes; regrowth dynamics can improve after grazing passes.
    • Animal welfare benefits: UMN trials showed lower respiration rates and 0.5–1.0 °F lower internal body temperatures during hot afternoons for shaded cows—meaningfully less heat stress.
    • Forage production holds up (or improves): Certain mixes (e.g., orchardgrass, meadow fescue; grass-legume combos) produced equal or greater biomass under panels with no drop in nutritive value.
    • Design for cattle, not fear: After a decade of on-farm experience, Brad’s team hasn’t seen cattle damage panels; people and tractors are more likely risks than cows.
    • Practical layouts: Keep inverters outside fences, route wiring high/inside racking, and allow equipment lanes; rotational grazing and (potentially) virtual fencing fit well.
    • Innovation on wheels: A 20 kW mobile bifacial shade rig with onboard batteries can power irrigation, fencing, and even an electric tractor—bringing agrivoltaics to wherever cattle need relief.

    Research & projects mentioned

    • Silicon Ranch – Cattle Tracker: multi-year cattle-PV integration study; Phase 2 is a 4.5 MW Tennessee “outdoor test lab” comparing array vs. open pasture for behavior, space use, health/performance, plus mirrored ecosystem monitoring.
    • Comprehensive literature review (AGU Earth’s Future – in press): Maps intersections among livestock–solar–land, identifies six research gaps (integration, layered ecology, modeling, best practices, social dimensions, collaborative science).
    • UMN Morris agrivoltaics demos: Fixed-tilt arrays at 6–8 ft (1.8–2.4 m) leading edge; 0.5 MW pasture array powering campus; vertical bifacial and crop-under-PV pilots coming; EV fast charger powered by cow-shade solar.

    Who it’s for

    Developers, ranchers, extension pros, and policy folks exploring dual-use solar that keeps grasslands working and cattle comfortable.
