implants, steers, feedlot
Crossbred yearling steers were used to determine the relative efficacy of specific anabolic implant combinations and sequences on feedlot performance and carcass traits. Steers were fed a high concentrate finishing diet for 112 days. lmplanting was done on days 1 and 42 of the feeding period. lmplanting improved (P < .05) average daily gain (ADG) 22% and feed efficiency 15%. Implant treatment generally increased dry matter intake. Lmplanting increased (P<.05) the rib eye area of carcasses 6.5% and tended to cause a reduction in percentage choice carcasses. The percentage of abscessed implants ranged from < 1 % to 10%, depending on the type of implant used even though implant needles were disinfected between each use.
