Hello there,

In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Carla Bittar, an associate professor at the University of Sao Paulo, shares her research on the thermoregulatory responses of dairy calves when fed varying amounts of colostrum. Dr. Bittar discusses the impacts of colostrum feeding on calf metabolism, growth, and immune function, especially under cold stress conditions. Tune in to gain valuable knowledge on colostrum management strategies for dairy calves.

"We have seen a lot of problems with calves that are born during the winter and wanted to know if feeding more colostrum would protect them against cold stress."

Meet the guest: Dr. Carla Maris Machado Bittar graduated in 1994 in Agricultural Engineering from ESALQ/USP. She earned her Master of Science from the University of Arizona in 1997 and completed her Ph.D. in Animal Science and Pastures from ESALQ/USP in 2002. Currently, she is a professor of dairy cattle management and nutrition at the Department of Animal Science at ESALQ/USP. Her research focuses on the nutrition and metabolism of growing dairy cattle, emphasizing the weaning phase.
