Effects of Feeding Heat-Treated Colostrum on Passive Transfer of Immune and Nutritional Parameters in Neonatal Dairy Calves


“The most exciting result from this study was that feeding heat-treated colostrum resulted in greater serum IgG concentrations in calves, despite the fact that calves in both treatment groups were fed the same total mass of IgG at the same time after birth and using the same feeding method. The authors hypothesize that greater serum IgG concentrations could have resulted because calves receiving heat-treated colostrum were able to absorb a greater proportion of the total mass of IgG presented to the small intestine.”
