Abstract
A commercial feedlot experiment utilizing 12 pens and 1038 steers evaluated initial implant strategies for feedlot steers. Steers were administered either Revalor-IS® or Synovex S® at initial processing. Both treatment groups received Revalor-S® as a terminal implant. Revalor-IS® as an initial implant improved hot carcass weight and carcass adjusted final weight; however, there was no effect on any other measure of performance or carcass characteristics. Selling steers on a carcass merit basis resulted in a similar return per head for both implant strategies. Reduced-dose combination implants may improve hot carcass weight and carcass adjusted final weight with no impact on carcass merit.
