Effects Of Estradiol-Trenbalone Acetate Implant Combinations On Feedlot Performance And Carcass Traits Of Two Steer Types, R.H. Pritchard, D.H. Gee, M.A. Robbins
South Dakota Beef Report, 1990
Hereford x Angus (HA) and predominantly Gelbvieh cross (Gx) steer calves either received no implant (control) or were implanted initially and again at 77 days on feed with a combination of estradiol and trenbalone acetate based implants. Calves were started on feed in December weighing 677 Ib and fed for 146 to 167 days. Fed for a common period of time, implanting steers increased (Pc.05) ADG, dry matter intake, final weight, carcass weight, rib fat thickness and yield grade. Implanting reduced (Pc.01) marbling scores. Gx steers were heavier and grew more rapidly than HA steers. There were no interactions between …

South Dakota Beef Report, 1990
One hundred twenty-three yearling black baldy steers were fed in one pen for 123 days at a commercial feedlot near Kimball, South Dakota. On day 1 in the feedlot, 53 steers were implanted with Synovex-S, 53 steers were implanted with the combination of Synovex-S and Finaplix-S and 17 steers received no implant. On day 60 in the feedlot, 18 of the Synovex-S steers and 18 of the combination steers were reimplanted using Synovex-S. Also on day 60, 18 of the Synovex-S steers and 18 of the combination steers were reimplanted using the combination of Synovex-S and Finaplix-S. The remaining steers …
