high concentrate diet, estradiol, trenbolone acetate, finishing steers
The effect of implant dosing pattern on anabolic response was evaluated in predominately Angus steers (n=192). Steers, except the control, were implanted with 1 of 3 different implant strategies. Cumulatively all implant treatments received a dose of 24 mg estradiol 17-β (E2) and 120 mg trenbolone acetate (TBA). Dosing patterns were 8 mg E2 and 40 mg TBA given 3 times; 12 mg E2 and 60 mg TBA given 2 times or 24 mg E2 and 120 mg TBA given 1 time. Implanted cattle had heavier body weights, increased average daily gain, and lower feed conversion compared to non-implanted controls. There were no differences among the implant treatments for cumulative 133 d body weight gain or average daily gain. Carcass quality was not affected by implant or implant dosing pattern. Dosing pattern did have an affect on growth patterns.
