Abstract

Calves with failure of passive transfer are much more susceptible to disease and death than calves with adequate colostral immunoglobulin G (lgG) absorption. Although colostrum is vital to calf health, it can also serve as a vector for pathogens such as Salmonella spp, Listeria monocytogenes, Escherichia coli, Mycoplasma bovis, and Mycobacterium avium subsp. paratuberculosis (MAP), the causative agent of Johne's disease. While batch pasteurization at traditional times and temperatures (145°F [63°C] for 30 minutes) will kill pathogens in colostrum, it destroys significant amounts of lgG. Our objective was to determine if we could use a lower temperature/longer time approach to kill pathogens while still preserving IgG content and activity.
