In this episode of The Dairy Podcast Show, Dr. Theresa Casey from Purdue University explains how coordinated metabolic alterations and mammary-specific changes support lactation. The discussion connects transition cow physiology, circadian rhythms, and nutrient partitioning that drive milk synthesis while maintaining metabolic balance. Dr. Casey also discusses seasonal patterns in colostrum production and how balance supports long-term performance. Listen now on all major platforms.

"Predictable routines allow animals to maintain homeostasis and handle large metabolic demands."

Meet the guest: Dr. Theresa Casey earned her MS in Animal Sciences and PhD in cell and molecular biology from the University of Vermont. She is an Associate Professor at Purdue University, focusing on mammary gland development, lactation physiology, circadian rhythms, and metabolic adaptation in dairy cattle.
