Comparison Of Estradiol-Trenbolone Acetate Implant Programs For Yearling Steers Of Two Genotypes, Robbi H. Pritchard
South Dakota Beef Report, 2008
Yearling steers (n = 400) were used to evaluate relative payout periods for implants when feeding high grain content diets. Implant treatments included (1) control (nonimplanted), (2) Synovex Plus, (3) revalor-s, and (4) Ralgro-revalor-s. The Synovex Plus (2), revalor-s (3) and Ralgro (4) were administered on day 1. The reimplant with revalor-s (4) was admnistered after 56 d on feed. Steers were managed in two groups. Initial BW and days fed were 782 lb, 131 d (Group I), and 661 lb, 145 d (Group II). Implants increased production rates and efficiencies, increased carcass size and reduced marbling when compared to …
