Abstract

Twenty-three male goats of three genetic groups were used: 8 Alpine (A), 4 ½ Boer + ½ Alpine (½ BA) and 11 ¾ Boer + ¼ Alpine (¾ BA), from which 11 animals were the control group (4 A, 2 ½ BA and 5 ¾ BA) and 12 received rbST (4 A, 2 ½ BA and 6 ¾ BA). Growth hormone used was recombinant bovine somatotropin (rbST) (T2) and animals from control group (T1) received 0.3 mg kg-1 of body weight of saline solution, from 45 days of life, adjusted at 14 days intervals. It was not detected the influence of rbST in carcass characteristics evaluated. Animals from Alpine breed showed higher values of carcass internal length and leg length in relation to ¾ BA animals. Alpine breed goat showed higher muscle/fat related to animals ¾ BA. It was not evident the superiority of half-breed Boer animals in relation to Alpine breed on goats carcass characteristics of growing. However, Alpine breed showed unfavorable characteristics, by higher carcass internal length and shoulder bone proportion.
