Bovine respiratory disease (BRD), or "Shipping Fever", continues to be the most costly disease of stocker and feeder cattle. Recent weaning, movement through auction markets, commingling and shipment are significant stressors. Recently received, stressed calves are particularly vulnerable to infection with respiratory viruses and bacteria, especially Pasteurella hemolytica. Morbidity rates in stocker calves of southeastern origin often exceed 50%, and mortality rates are commonly 2-4%. The objective of this study was to compare efficacy of tilmicosin and ceftiofur, the two drugs most recently approved by the FDA for treatment of BRD.
