Comparison of Revalor XS to a Revalor IS / Revalor S Implant Strategy in Finishing Steers

A commercial feedlot study compared effects of Revalor IS/Revalor S (RevIS-S) implant strategy to a Revalor XS (RevX) single implant strategy on performance and carcass characteristics of feedlot cattle. There were no differences (P \u3e 0.90) in DMI, final BW, ADG, or F:G. Hot carcass weight, marbling score, 12th rib fat, LM area and calculated yield grade also were unaffected (P \u3e 0.10) by implant strategy. The RevX treatment resulted in a greater (P \u3c 0.01) percentage of Choice carcasses than RevIS-S. Cattle receiving Revalor XS performed similar to cattle implanted with RevIS-S using a traditional reimplant program

Comparison of Revalor-XS vs. Two Common Implant Strategies in Finishing Steers

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 \u3c 0.05) final BW and lower F:G (P \u3c 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 \u3c 0.05) of yield grade 1 and 2 carcasses than other implant treatments, while cattle receiving TE-200 had greater (P \u3c 0.01) yield grade 3 and 5 carcasses
