This study was developed with the aim of evaluating recombinant bovine somatotropin (rbST) on non-carcass components of goat kids of three genotypes. It was used 23 male goat kids of three genotypes, being 8 Alpine, 4 1/2 Boer + 1/2 Alpine (1/2 BA) and 11 3/4 Boer + 1/4Alpine (3/4 BA), from which 12 received rbST e 11 control. The growth hormone used was the recombinant bovine somatotropin (rbST) and animals of treatment 1 received the hormone in the amount of 0.3 mg/kg live weight, from 45 days, adjusted in intervals of 14 days. Animals of treatment 2 (control) received saline solution in the same dosage and interval. The 1/2 BA goats presented a higher proportion of external non-carcass components (head, feet and skin) in relation to Alpine goats. Regarding the vital organs, such as lungs, kidneys and spleen, and the noncarcass components blood, internal fat and perinephric fat, Alpine goats presented higher values than 3/4 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.142143150Amin, M.R., Husain, S.S., Islam, A.B.M.M., Evaluation of Black Bengal goats and their cross with the Jamunapari breed for carcass characteristics (2000) Small Ruminant Research, 38, pp. 211-215Cameron, M.R., Luo, J., Sahlu, T., Hart, S.P., Coleman, S.W., Goetsch, A.L., Growth and slaughter traits of Boer x Spanish, Boer x Angora, and Spanish goats consuming a concentrate-baseddiet 24-7-89 (2001) Journal of Animal Science, 79, pp. 1423-1430Carvalho, P.A., Sanchez, L.M.B., Viégas, J., Velho, J.P., Jauris, G.C., Rodrigues, M.B., Componentes do peso vivo e órgãos viscerais de bezerros machos de origem leiteira ao nascimento, 50 e 110 dias de vida (2003) Revista Brasileira de Zootecnia, 32 (6), pp. 1469-1475Coleman, S.W., Evans, B.C., Guenther, J.J., Body and carcass composition of Angus and Charolais steers as affected by age and nutrition.
