Abstract

Carcass characteristics and edible portion yields of Nellore€”steers compared to crossbreds (F1) of Canchim, Santa Gertrudis, Caracu, Holstein and Swiss as sire breeds mated with Nellore. II. Pasture finished cattle. The NN crossbreds had a significantly heavier live weight (429.8 kg) than KN (470.1 kg), CN (468.1 kg), GN (465.7 kg) or SN (465.0 kg) and NN wich had the lowest live weight (421.2 kg). Consequently, HN had heavier hot and chilled carcass weights (266.8 and 261.4 kg) than CN (262.6 and 256.8 kg), KN (254.1 and 248.9 kg) and GN (252.6 and 247.6 kg). SN was lower (248.1 and 242.7 kg) and NN the lowest (233.5 and 230.4 kg). CN (48.2%) and NN (47.4%) had higher percentages of special hindquater than SN (47.0%), GN (46.6%) with KN (46.0%) and HN (46.0%) having the lowest percentage. The edible portion percentage was higher for CN (72.3%), KN (71.9%), NN (71.5%), SN (71.4%) and HN (71.3%) than GN (69.0%). The KN crossbred had a significantly lower percentage of bone (18.2%) than HN (19.1%) with NN and other crossbreds intermediate. Fat thikness per 100 kg of carcass weight was significantly lower for the crosses than for NN (1.9 mm). Loin eye area per 100 kg carcass weight, measured at 12th rib, was larger for SN (31.9 cm2) than for HN (27.5 em2) with NN and the other crosses intermediate. Trimming percentage was lower for NN and crosses than for GN (12.6%). The CN, NN and SN steers had significantly higher percentages of special hindquarter, which is desirable because this is the carcass portion that contains the higher quality and priced cuts. From the standpoint of producing higher percentages of edible portion (total boneless closely trimmed retail cuts), CN, KN, NN, SN and HN were higher than GN.
