Metaphylactic antimicrobial therapy for bovine respiratory disease in stocker and feedlot cattle.
This article provides an overview of implementing metaphylactic antimicrobial protocols to certain classes of cattle on arrival to stocker and feedlot production systems. The goal of this management practice is to reduce the negative health and performance effects induced by bovine respiratory disease (BRD). This article emphasizes the multiple factors that influence the decision for mass medication, including weight (age) of the cattle, distance traveled, environmental conditions, previous health history, visual inspection of the cattle at arrival, and prediction of the risk of disease. Current data suggest that metaphylactic programs significantly reduce negative health effects and improve feed performance that can be observed in cattle stricken with BRD.
