Abstract

While the most important route of transmission of Mycobacterium avium subsp. paratuberculosis (MAP) is generally considered to be through the ingestion of infective feces from the calf's environment, other potential sources of transmission could include shedding (or post-harvest contamination) of MAP in colostrum or milk. The importance of consuming raw milk in MAP transmission to calves has not been quantified. The objective of this study was to describe if feeding pasteurized non-saleable milk from a Johne's infected herd controlled the transmission of MAP in calves, as compared to calves fed commercial milk replacer, under conditions of natural exposure.
