Johne’s Disease in Beef Cattle

Abstract

The economic cost of Johne’s disease is substantial due to delayed establishment of pregnancy and even failure during the breeding season, reduced weaning weights, and loss or culling of cows before operations have recouped production costs. This publication aims to inform ranchers, ranch workers, Extension agents, cattle owners, livestock-agricultural students, and interested residents about important Johne’s disease facts. Written by Bridget Stice, Lindsey Wiggins, Todd Thrift, and João Bittar, and published by the Veterinary Medicine—Department of Large Animal Clinical Sciences, UF/IFAS Extension, October 2023.
