Abstract

A study was conducted in Alberta, Canada utilizing 4 commercial feedlots to compare the clinical efficacy of gamithromycin to florfenicol for the initial treatment of undifferentiated fever (UF) in winter-placed feedlot calves. There were no significant differences (P>0.05) in UF relapse rates and crude case fatality or bovine respiratory disease/histophilus fatality rates between the 2 treatment groups. As a result, the cost-benefit of gamithromycin versus florfenicol was based on the difference in treatment cost between the 2 drugs. Using current market prices and a treatment weight of 750 lb (340 kg), gamithromycin had an economic advantage of $11.52 CAN per head over florfenicol.
