Abstract

Identifying and removing MAP-infected cattle in the early stages of disease, prior to shedding of the organism, will allow producers to prevent entry or spread of the causative agent of JD within a herd. This investigation was funded in part by the Iowa Livestock Health Advisory Council. Presented in part at the Second Annual Johne's Disease Integrated Conference, January 26-29th, University of California, Davis.
