Resumo: | The aim of this study was to compare four genetic groups of sheep on the carcass and meat quality traits. Thirty-three contemporary and unrelated male lambs, all of single birth were used in the experiment, being thirteen from the Santa Inês (SI) breed, seven from the Brazilian Somali breed (BS), six from the Morada Nova (MN) breed and seven from the ½ Dorper - ½ Morada Nova (F1) crossbreed. The genotypes SI, BS and F1 presented similar performances in relation to hot and cold carcass weights, which values were 10.76±0.53kg and 10.46±0.52kg for SI, 9.20±0.73kg and 8.99±0.71kg for BS, and 9.35±0.73kg and 9.13±0.71kg for F1, respectively. The BS had a better hot carcass yield (47.10±0.88%) and cold carcass yield (46.00±0.87%). Better carcass conformation was observed in SI and F1 (2.73±0.12 and 2.50±0.17, respectively) while the BS presented a better finishing (3.29±0.20). The average for the rib eye area (REA) was 9.94±0.49cm², 8.66±0.67cm², 7.18±0.72cm² and 9.8±0.67cm², and for the carcass compactness index (CCI) it was 0.17±0.01kg/cm, 0.17±0.01kg/cm, 0.11±0.01kg/cm and 0.16±0,01kg/cm, for SI, SB, MN and F1, respectively. There were no significant differences between SI, BS and F1 regarding REA and CCI. Although, in general, the MN presented a relatively lower performance than the other genotypes, this breed had similar carcass yields and fat thickness when compared to SI and F1 and similar conformation and REA in comparison to the BS. Regarding meat quality, no differences were observed between genotypes, except for redness and cooking losses. It is concluded that no one group had a higher or lower performance in all traits analyzed. Moreover, for the management conditions employed in this study, there was evidence of greater specialization in meat production for genotypes SI, BS and F1 when compared to MN, although there are no substantial differences between the four groups regarding meat quality. |

Trinta e três cordeiros, contemporâneos, nascidos de parto simples e sem relação de parentesco, foram utilizados no experimento, sendo 13 da raça Santa Inês (SI), sete da raça Somalis Brasileira (SB), seis da raça Morada Nova (MN) e sete ½ Dorper - ½ Morada Nova (F1). Os genótipos SI, SB e F1 apresentaram desempenhos similares quanto ao peso das carcaças quente e fria, cujos valores foram 10,76±0,53kg e 10,46±0,52kg para o SI, 9,20±0,73kg e 8,99±0,71kg para o SB, 9,35±0,73kg e 9,13±0,71kg para o F1, respectivamente. A raça SB apresentou melhor rendimento de carcaça quente (47,10 ±0,88%) e de carcaça fria (46,00±0,87%). Os genótipos SI e F1 apresentaram melhores conformações (2,73±0,12 e 2,50±0,17, respectivamente), enquanto o SB apresentou melhor acabamento (3,29±0,20). As médias para área de olho de lombo (AOL) foram 9,94±0,49cm², 8,66±0,67cm², 7,18±0,72cm² e 9,8±0,67cm² e para o índice de compacidade da carcaça (ICC) foram 0,17±0,01kg/cm, 0,17±0,01kg/cm, 0,11±0,01kg/cm e 0,16±0,01kg/cm, para SI, SB, MN e F1, respectivamente. Não houve diferença significativa entre os genótipos SI, SB e F1 quanto à AOL e ao ICC. Apesar de, no geral, a raça MN apresentar desempenho relativamente inferior aos demais genótipos quanto às características de carcaça analisadas, essa raça apresentou rendimentos de carcaça e espessura de gordura similar ao SI e F1 e conformação e AOL similar ao SB. Não houve um grupo superior ou inferior para todas as características analisadas. Por outro lado, para as condições de manejo empregadas neste estudo, evidenciou-se maior especialização para produção de carne dos genótipos SI, SB e F1 em relação ao grupo MN. Não houve diferenças importantes entre os diferentes genótipos quanto à qualidade da carne.EmbrapaFundacao Cearense de Apoio ao Desenvolvimento Cientifico e Tecnologico - FUNCAPUniversidade Federal do CearaUniversidade Estadual PaulistaEmbrapa Caprinos e OvinosUniversidade Estadual PaulistaUniversidade Federal de Minas Gerais (UFMG), Escola de VeterináriaUniversidade Estadual Paulista (Unesp)Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA)Fernandes Júnior, G.a.
