A commercial feedlot experiment was performed with the objective to compare a Synovex-Choice/ Synovex-Choice (Choice) implant strategy to a Revalor-IS/Revalor-S (Revalor) strategy on finishing steer performance and carcass characteristics. DMI did not differ between treatments). When calculated from carcass adjusted FW, ADG was not significantly different between Choice and Revalor implant strategies. Consequently, F/G was not significantly different when the Choice strategy was compared with Revalor strategy. No differences were observed for marbling scores or calculated yield grade) due to treatment. Based on carcass-adjusted performance, significant differences do not exist in performance between the two implant strategies.
