Abstract

A commercial feedlot experiment was performed to compare the effects of a Component TE-IS/TE-S with Tylan (TE-IS/S) implant strategy to a Component TE-200 with Tylan (TE-200) or a Revalor XS (Rev-XS) single implant strategy on performance and carcass characteristics of feedlot steers. Cattle receiving the TE-IS/S implants and the Rev-XS implant had greater (P < 0.05) final BW and lower F:G (P < 0.05) than the cattle that received the TE-200 treatment. Daily gain was improved (P = 0.04) when comparing TE-IS/S to TE-200, but intermediate for steers that received the Rev-XS treatment. Quality grade categories were unaffected by implant strategy. Cattle given TE-IS/TE-S had a greater number (P < 0.05) of yield grade 1 and 2 carcasses than other implant treatments, while cattle receiving TE-200 had greater (P < 0.01) yield grade 3 and 5 carcasses.
