In this part one episode of The Dairy Health Blackbelt Podcast, Dr. Amanda Fischer-Tlustos, NSERC postdoctoral research fellow at UC Davis and the University of Guelph, explains how colostrum is produced and what drives its composition. She shares new findings on IgG accumulation, macronutrient synthesis, mammary activity during the dry period, and management factors influencing colostrum quality. Discover practical insights to improve dairy health outcomes. Listen now on all major platforms!

“Higher milk yield at dry off was linked to greater mammary activity during the dry period and poorer colostrum outcomes.”

Meet the guest: Dr. Amanda Fischer-Tlustos is an NSERC postdoctoral research fellow at UC Davis and the University of Guelph, specializing in whole body and mammary metabolism. She completed her MSc at the University of Alberta, studying colostrum management, and her PhD at the University of Guelph, focusing on maternal and mammary factors affecting colostrum production and composition.
