Contemplating Colostrum with Robert Van Saun

Join us for this discussion about colostrum evaluations and benchmarking Dr. Robert VanSaun from Pennsylvania State University. This episode covers IgG concentration, evaluating passive transfer, heat treatment of colostrum, and remaining knowledge gaps in the world of small ruminant colostrum.

Today's episode references several papers including:
