On the Uplevel Dairy Podcast, Peggy Coffeen interviews Dr. Stephanie Hansen of Iowa State University at Adisseo’s VIP seminar about why beef-on-dairy calves often fail to thrive in the feedlot. Hansen, a feedlot “mineral nerd,” explains how high liver copper—seen in necropsy results at 800–900 ppm—can originate from late-gestation cow diets and be compounded in dairy systems by copper-fortified milk replacer and starter feed while calves are still functionally monogastric, leading to greater absorption. Research funded by the Iowa Beef Checkoff found high liver copper did not affect vaccine response but did worsen outcomes in a respiratory disease challenge, increasing fever, clinical signs, and lung consolidation, alongside systemic inflammation and potentially compromised liver health. Action steps include moderating copper in late-gestation and calf starter diets, avoiding feedlot copper over-fortification, reassessing frequent vaccination protocols, and considering zinc’s anti-inflammatory benefits. Hansen also notes she writes national-park crime thrillers under the pen name SL Hansen, with a new book due April 2026.

This week on the Uplevel Dairy Podcast, we’re bringing you our breakout session from the Central Plains Dairy Expo for a real, unfiltered conversation with dairy’s rising leaders. From coming back to the farm… to carving your own path… to earning respect and finding your voice—this is a must-listen not only for the next generation, but for senior leaders looking to better understand, develop, and lead them.

We are proud to partner with Central Plains Dairy Expo to feature these four panelists:Jacob Wag, Wag's Blue and White Dairy; Emma Brockshus, Brockshus Dairy; Emmett Meissner, Norm-E-Lane Farm, and Chelsea Abbott, Trans Ova Genetics.

Hear it straight from these rising leaders.

On location at Brooks Farms in Waupaca, Wisconsin, Peggy Coffeen interviews Dr. Amanda Onan of United Vet Services (Heritage Vet Partners) about how teamwork shapes her approach to dairy veterinary medicine nearly 10 years into practice. A second-generation veterinarian, Dr. Onan describes learning through ride-alongs with her father and hands-on work at Sugar Creek Farms, including projects to improve somatic cell count and mastitis understanding. She shares a formative lesson from a 70-year-old farm owner scraping stalls, reinforcing that no one is above any task and that every employee’s observations matter. Dr. Onan emphasizes building trust by engaging employees, recognizing positives, and using empathy to improve farm efficiency, while also discussing compassion fatigue in veterinary medicine and the support systems that help. She notes that Heritage’s national network enables collaboration, and she sees AI changing record analysis and on-farm implementation.
