In this episode of The Dairy Health Blackbelt Podcast, Dr. Tasia Kendrick, Associate Professor at Michigan State University, explains why bovine leukemia virus remains a major but often overlooked challenge in US dairy herds. She outlines prevalence levels, transmission routes, impacts on immunity and longevity, and practical management strategies to reduce spread. Dr. Kendrick highlights proactive approaches that protect animal welfare and herd performance. Listen now on all major platforms!

“Animals with bovine leukemia virus often show reduced milk production, shorter herd life, and weaker immune responses that affect overall dairy herd performance.”

Meet the guest: Dr. Tasia Kendrick is an Associate Professor in the Department of Animal Science at Michigan State University. Trained as a geneticist, her research focuses on bovine leukemia virus prevalence, transmission, and management in dairy and beef herds, alongside innovative diagnostic approaches. Her work supports evidence-based decision-making to improve dairy health and longevity.

In this episode of The Dairy Health Blackbelt Podcast, Dr. Sabine Mann, Associate Professor at Cornell University, continues the discussion, now focusing on cow calf separation and the physiology behind delayed separation strategies. She explains current research on transition milk, calf health, and cow outcomes, while addressing common assumptions and management concerns. Listen now on all major platforms!

“One major goal of this cow calf separation research was to separate nutritional effects from social contact effects, allowing a clearer understanding of how transition milk alone influences calf physiology.”

Meet the guest: Dr. Sabine Mann is an Associate Professor of Ambulatory and Production Medicine at Cornell University. Her research focuses on the intersection of metabolism, nutrition, and immunology, with emphasis on transition cows and newborn calf resilience. Her work connects physiology with practical dairy health decisions.

In this episode of The Dairy Health Blackbelt Podcast, Dr. Sabine Mann, Associate Professor at Cornell University, explains how colostrum volume influences passive immunity, digestion, and calf comfort. She discusses body weight-based feeding strategies, absorption efficiency, and behavioral responses linked to excessive volumes. Practical insights help refine colostrum programs for modern dairy systems. Strengthen your evidence-based colostrum management decisions for calves. Listen now on all major platforms!

“Calves range in size and weight, and that variation raises important questions about whether one standard colostrum volume fits every newborn calf.”
