Abstract

Heat-treating colostrum by the use of batch pasteurizers is an effective method to reduce bacterial contamination while protecting immunoglobulins and enhancing passive transfer and health in calves. The Perfect Udder® bag (Dairy Tech Inc., Windsor, CO) is designed to heat-treat 1 gallon (~4 L) of colostrum at a time prior to storage and feeding; however, this system has not been validated. The objective of this study was to compare passive transfer of IgG in neonatal calves that were fed colostrum that was heat-treated with the Perfect Udder® system, heat-treated with a batch pasteurizer (positive control), or fresh-refrigerated or fresh-frozen (negative controls).
