. Effects of hormonal growth promotant (HGP) implantation on liveweight, carcass and meat quality measurements were examined using 80 Angus yearling cattle. After entry to the feedlot, 40 steers and 40 heifers were implanted with Revalor-S (28mg oestradiol and 140mg trenbolone acetate) and Revalor-H (20mg oestradiol, 200mg trenbolone acetate), respectively. Cattle were slaughtered after 55 and 65 days on feed. Samples from the Mm. longissimus dorsi,bicepsfemoris(thecapandbodyportions),gluteusmedius(theeyeandDportions),infraspinatusandtricepsbrachii werepreparedforsensorytestingafteragingfor5and21daysafterslaughter.Atotalof854musclesampleswerecookedby grill (601) or roast (253) methods,and served to consumers,using the Meat Standards Australia taste panel protocols.

Implantation resulted in an increased ossification score in steers (P <0.05), but not in heifers.

Muscles differed in their response to HGP implantation (P <0.05) for tenderness, overall liking and palatability scores. Muscles also differedintheiragingratesafterslaughter(P <0.05).ThegreatestresponseinsensoryscorestoHGPimplantationwasfound in those muscles,that had the highest aging rates. Possible mechanisms,by which muscles differed in their response to HGP implantation are discussed.
