Abstract

Previous research showed that heat-treatment of colostrum at 140°F (60°C) for 60 minutes results in a significant reduction in colostral bacteria counts without affecting colostral immunoglobulin concentrations. Moreover, calves fed heat-treated colostrum have improved serum lgG levels when compared to calves fed raw colostrum. It is unclear whether feeding heat-treated colostrum will improve growth or health in preweaned calves. The objective of this study was to describe the effect of feeding heat-treated colostrum on average daily gain (ADG), risk for morbidity, and mortality in pre-weaned calves.
