Evaluation of Implants, Clover, and Fescue Variety on Stocker Steers – Year 2

Sixty-four growing steers were used in a split-plot experiment, where the whole plot was pasture, and implant level. Whole treatment 4 × 2 factorial with four levels of fescue (High Endophyte, Low Novel, or Endophyte Free) two legume (Legumes No Legumes). The included (No Implant, Synovex One Grass, Revalor-G, Ralgro). Data collected weights, hair coat scores, length, rectal temperature (every 28 days), ultrasound carcass characteristics when coming off grass. Steers on High had lowest average daily gain (ADG) final weight smallest loin muscle as compared to all other types. differentiation observed beginning at day 56 through end study. Overall, ADG not impacted by addition legume. that implanted Grass greater gain, weight, lower score non-implanted steers. For many measures, Ralgro Revalor-G resulted changes between those receiving Grass. high endophyte than Ralgro, being intermediate. Gains for free pastures also type gains steers, In this second year research, use low no implants increased gains.
