The heifers grazed native grass pastures for 122 days, stocked at 4 acres per head. The heifers receiving the Implus-H tended to gain faster (P<.12) than the Ralgro heifers. No difference in gain occurred between the Implus-H and Synovex-H heifers.BeefImplantGrazing cattleNative grassConference paper
