Implant Combinations And Reimplanting Strategies For Yearling Steers Fed High Concentrate Diets, R. H. Pritchard, M. A. Robbins, D. H. Gee
South Dakota Beef Report, 1992
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.
