Abstract

This study was developed with the aim of evaluatingrecombinant bovine somatotropin (rbST) on non-carcasscomponents of goat kids of three genotypes. It was used23 male goat kids of three genotypes, being 8 Alpine, 4 ½Boer + ½ Alpine (½ BA) and 11 ¾ Boer + ¼Alpine (¾BA), from which 12 received rbST e 11 control. Thegrowth hormone used was the recombinant bovinesomatotropin (rbST) and animals of treatment 1 receivedthe hormone in the amount of 0.3 mg/kg live weight, from 45 days, adjusted in intervals of 14 days. Animals oftreatment 2 (control) received saline solution in the samedosage and interval. The ½ BA goats presented a higherproportion of external non-carcass components (head, feetand skin) in relation to Alpine goats. Regarding the vitalorgans, such as lungs, kidneys and spleen, and the noncarcasscomponents blood, internal fat and perinephric fat,Alpine goats presented higher values than ¾ BA goats.The administration of recombinant bovine somatotropin (rbST) did not produce effect on proportions and weight of non-carcass components. Proportions and weight of non-carcass components varied in function of genotypes, although animals were slaughtered at similar live weight.
