Abstract

Mycobacterium avium subspecies paratuberculosis (MAP), the agent of Johne's disease, spreads through beef cattle herds with little awareness by beef cattle producers. The objectives of this study were to accurately estimate the proportion of beef cattle herds with 5% or more of the adult herd infected with MAP, and to identify herd-level practices and conditions associated with Johne's disease herd status so that veterinarians could help beef cattle producers accurately assess and/or modify their risk for introducing MAP into, and allowing it to spread within, their herds.
