Abstract

Liveweights were significantly higher for crossbred animals than for pure bred Nellore (517.4, 483.0, 477.2, 475.0, 461.1 and 424.6 kg, respectively for HN, SN, GN, CN, KN and NN). Therefore, hot and chilled carcass weights were higher for crossbreds than for Nellore (300.7, 279.2, 277.0 287.7, 264.9 and 249.0 kg, respectively for HN, SN, GN, CN, KN and NN). Significantly higher percentages of special hindquarter were observed for NN (44.9%) and CN (45.3%) than for SN (44.1%), HN (43.8%) and KN (43.6%) with GN (44.3%) intermediate. Therefore, significantly lower forequarter percentages were observed for NN, CN and GN than for HN, SN and KN. The ponta de agulha cut (flank, plate and shortribs) was significantly lower for CN and SN than for GN, HN and KN with NN intermediate. Kidney, pelvic and inguinal fat percentage was significantly lower for SN (4.0%), CN (4.1%), GN (4.0%), HN (4.2%) and KN (4.1%) than for NN (4.9%). The percentage of total boneless and closely trimmed retail cuts (edible portion) was higher for CN (74.8%), KN (74.7%), SN (74.5%) and HN (74.3%) than for NN (72.4%) with GN (73.9%) intermediate. Higher bone percentages were observed for HN crossbreds than for CN, KN, NN and SN, GN being intermediate. The loin area per 100 kg carcass weight was significantly greater for CN and GN than for KN, HN and NN, with SN intermediate. Fat thikness per 100 kg carcass weight was significantly greater for NN than for the other groups.
