Abstract

A randomized complete-block design trial was conducted in a commercial finishing feedlot in southern Alberta, Canada using winter-placed heifer calves (n = 4574; initial body weight 6 72 ± 43 lb; 305.5 ± 19.5 kg) to evaluate the comparative efficacy of metaphylactic treatment with gamithromycin or tildipirosin for control of bovine respiratory disease. There were no statistically significant differences (P > 0.05) in health or feedlot performance between calves treated with gamithromycin or tildipirosin from arrival to terminal weight sort, approximately 30 days before slaughter. Using current drug prices, metaphylactic treatment with gamithromycin had a net economic advantage of $4.13CAN/head to those treated with tildipirosin on arrival.
