In this episode of DairyVoice, Connie Kuber of Sealpro Silage Barrier Films talks with Dr. Julia Reyes-Hamann, who is the senior technical specialist for dairy young animal nutrition in North America for Cargill Animal Nutrition. Dr. Hamann discusses a calf’s immune system and their lung health. From housing to nutrition, Dr. Hamman covers a lot of material in this podcast. She explains why usage of colostrum is the key and using starter mix. Sometimes there is a problem even when there are no outside obvious signs of trouble in the calf. Julia tells us what to look for.
