In this episode of The Feed Science Podcast Show, Dr. Lautaro Cangiano, from the University of Wisconsin–Madison, explores how colostrum management and early-life nutrition shape the immune development of dairy calves. He explains how timing, quality, and cleanliness of colostrum feeding directly influence disease resistance, gut health, and long-term productivity. Learn how new research is reshaping early calf care and immunity. Listen now on all major platforms!

“Contamination with bacteria during colostrum handling severely limits immunoglobulin absorption in calves.”

Meet the guest: Dr. Lautaro Cangiano is an Assistant Professor of Bovine Immunology at the University of Wisconsin–Madison. His research investigates how management practices, such as colostrum feeding and early-life interventions, influence immune function and health across a dairy cow’s lifespan. With a focus on practical, science-based strategies, his work helps producers enhance disease resistance and resilience in dairy herds.
