Abstract

An experiment was carried out with the carcasses of 78 male and female goat kids of five breed groups (Alpine; ½ Boer + ½ Alpine; ½ Anglo Nubian + ½ Alpine; ¾ Boer + ¼ Alpine; and ¼ Boer + ¼ Alpine + ½ Anglo Nubian), which were divided into two finishing systems (FS1, kid + dam on pasture; and FS2, weaned kid confined from 60 days of age onwards) and slaughtered at an average age of 120 days. The carcasses were cut in half and the left half was divided into the cuts of shoulder, leg, rib, loin and neck, which were dissected and separated into muscle, bone, fat and other tissues. Breed group, sex and finishing system influenced the yields of fat and bone in the carcass. Muscle yield was influenced only by the finishing system, whereas the yield of other tissues was influenced by sex. Crossing with the Boer breed influenced carcass tissue deposition, with the ½ Boer crossbred carcass exhibiting the highest degree of fatness. Females had a higher proportion of fat and a lower proportion of bones than males. Carcass muscle, fat and bone correlated significantly with all cuts. Rib and leg were the cuts that best represent the tissue composition of goat kid carcasses, based on the correlation coefficient and prediction equations.

Keywords: bone, crossbreeding, fat, muscle, prediction equations
