Desempenho e características de carcaças de cabritos terminados precocemente em confinamento.

Abstract

This work was carried out at the Experiment Station of Pendência, belonging to EMEPA (Agricultural Research Company of Paraíba, SA), located in the city of Soledade - PB, aiming to evaluate the biometric and carcass traits of goats as a function of the genotypes kept in confinement . Sixteen goats from the SPRD goats (No Definite Breeding Pattern) were used, with Savana (SA) and Boer (BO) breeders, which produced ½BO x ½SRD and ½SA x ½SPRD, using a completely randomized design. Biometrics and morphometry, carcass yields, commercial cuts and the qualitative characteristics of the carcasses were analyzed. The biometric variables did not show a significant effect (P> 0.05), except for the body score, where the Boer and SRD datasets presented the highest mean. There was no influence for all the variables (P> 0.05) of the genotypes on the morphometry of the carcasses of the studied animals. Losses due to carcass cooling showed no significant variation (P> 0.05) between the genetic groups. Regarding the qualitative characteristics, it was observed that the genotype ½ Boer x ½ SPRD presented, significantly, better conformation of carcass than the½ SA x ½ SPRD animals. As for marbling, there were no differences (P> 0.05) among the genotypes. Crossbred boar from the Boer breeding with SPRD presented better performance and conformation carcasses than the Savana and SPRD mestizos, the use of these breeds is an efficient tool to improve the meat production of these animals.
