Abstract

In this experiment two groups of six animals each were slaughtered and their carcasses were evaluated. One group consisted of 31 months old animals of the nelore breed with 408.75kg of live weight, and the other of 34 months old crossbreed animals, 1/2 Schwyz x 1/2 Guzera with 475.92kg of 1iveweight. The following carcass characteristics were considered in the experiment dressing percentage (considering the cold carcass weight), separable lean, bone, fat trimmed, meat of 1.st, 2.nd and 3rd quality. The values observed for the nelore and crossbreed, in the same order, the first as a percentage of the live weight and the others as a percentage of the cold carcass, were the following: 54.50 €” 52.48; 75.24 €” 74.92; 18.65 €” 19.03; 6.04 €” 6.05; 32.69 €” 34,13; 29.47 €” 28.53, and 13.08 - 12.25. The Nelore breed to have a greater dressing percentage (P < 0.05). The others significant differences were observed between grous, but the Nelore breed tendend to have a greater production of 2.nd and 3rd quality meat, and the crossbreed tendend to produce more 1.st quality meat. The similarities between the two groups in carcass characteristics, however, were high and there was no base lo indicate one as a better meat producer.
