Stewardship Toward Healthier Cows, a Sustainable Climate, and Responsible Antibiotic Use with Daryl Nydam, DVM, PhD | cohosted by Kimmi Devaney of the Progressive Dairy Podcast

49 minutes

Join us for a very special episode of Dairy Digressions with our first-ever guest cohost, Kimmi Devaney of the Progressive Dairy Podcast and former ADSA Undergraduate Student Division president. Joining host Matt Lucy, the two sit down with Daryl Nydam, DVM, PhD, dairy health and production professor who serves as a director in Cornell’s College of Veterinary Medicine and the faculty director at the Cornell Atkinson Center for Sustainability. Daryl’s journey—from his childhood in a dairy and veterinary medicine family to a college student studying science

while shooting hoops to working at the nexus of dairy, veterinary medicine, and human health—has been fascinating. Amidst growing consumer concerns about environmental and animal welfare issues, Daryl reassures listeners that cows today are thriving because of monumental advancements in veterinary care

and management. The discussion covers the importance of optimal replacement decisions to reduce enteric methane production and ensure that each herd has the best cows in the barn. The trio also gets into another critical conservation issue: antimicrobial resistance. Daryl explains a novel, pathogen-based strategy for clinical mastitis treatment during lactation so farmers can make economical and stewardship-driven decisions, thereby reducing the need for antibiotics and hospital pen time. Listeners can also learn more about selective dry cow therapy: For some farms, gone are the days of treating every cow at dry off; now, with advanced diagnostics, we can treat only those cows with infections or at high risk of acquiring an infection during the dry period, maintaining milk quality and herd health without unnecessary antimicrobial exposure. Join us in this enlightening episode as we navigate the intricate landscape of dairy stewardship and why we should all feel optimistic about the dairy industry.
