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.

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.

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.
