Abstract

During the fall of 2004, fall-placed feedlot calves that were diagnosed on gross postmortem examination with bovine respiratory disease (BRD) as the predominant cause of death were pathologically examined in detail using laboratory support to determine the microbiological agents involved in fatal BRD, and to determine if specific microbiological agents were associated with different pathological presentations of fatal BRD.
