| Resumo: |
The objective of this study was to evaluate the characteristics of carcass and non-carcass components in Brazilian semi-arid native goats of different genotypes in feedlot system. It was used 30 non-castrated Azul, Graúna and Moxotó goats with average initial weight of 15.93 ± 2.4, distributed in a completely randomized design with 3 genotypes and 10 replicates. The experimental diet used had a roughage:concentrate ratio of 47:53. There was a significant effect for weight gain and subcutaneous fat thickness according to genotype. Retail cut yields did not differ among the studied breeds. The percentage of non-carcass components in relation to live weight and empty body weight were not different among genotypes. Graúna and Azul genotypes showed daily gain greater than Moxotó genotype. The subcutaneous fat thickness presented by Azul and Moxotó genotypes was greater than that of Graúna genotype. All genotypes have good quantitative and morphometric carcass traits in addition to satisfactory yields of cut and non-carcass components, but for subcutaneous fat thickness (carcass finishing), Azul and Moxotó genotypes stand out.
