Grazing heifers spayed by the Kimberling-Rupp technique also responded similarly to Synovex-H and Synovex-S implants. During the finishing phase, heifers implanted with Synovex-S gained 5.7% faster than heifers implanted with Ralgro, and those implanted with Synovex-H were intermediate in performance. There was no statistical interaction between spaying method and implant treatment during either the grazing or finishing phases.BeefImplantHeifersSpayedConference paper
