Heifers that were flank-spayed plus rumen-ovarian autografted (FS+A)
responded similarly to Ralgro®, Synovex-H®, and Synovex-S® implants on' pasture.
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.
