Abstract

A single, 2-ml injection of a Mannheimia (Pasteurella) haemolytica bacterin-toxoid was administered subcutaneously to calves on arrival at the feedlot. Calves receiving the bacterin-toxoid had reduced crude mortality. There were no differences in BRD-specific mortality, morbidity or average daily gains (mean days on feed = 179).
