Resumo: The goal was to evaluate if feeding systems with or without milk or breed groups can improve carcass characteristics, the proportion of tissues and meat tenderness of feedlot goat kids. Were used 56 animals from five different breed groups fed by experimental diet and milk according to the treatment., without milk or with 1,5 L milk/animal/day. The kid goats were slaughtered at 30 kg of live weight, and the carcass conformation and amount of fat were determined subjectively by visual assessment. Morphometric measurements and carcass and cut yields were performed. The Longissimus lumborum muscle was separated to determinate the area and subsequently it was used to evaluate the tenderness of the meat. The feeding system changes goat carcass characteristics, and goat kids fed milk until slaughter have better carcass yield and meat quality, as it anticipates the deposition of total fat, which can benefit carcass quality, given the scarcity of fat in the carcass of goats. The breed group also influences carcass characteristics. It is recommended the use of the Boer breed up to 3/4, since more than that it reduces leg yield and does not improve the compactness index and carcass conformation.

Foram utilizados cinco grupos raciais, sendo: Alpino, Anglo-Nubiano, 1/2 Boer x 1/2 Alpino, 3/4 Boer x Alpino e 7/8 Boer x Alpino), e os sistemas de alimentação foram: dieta experimental sem leite e dieta experimental mais 1,5 L de leite/animal/dia. Os animais foram abatidos após atingirem 30 kg de peso vivo, e foram avaliadas medidas morfométricas, rendimento comercial da carcaça, índices de compacidade da carcaça e da perna, rendimento de cortes comerciais. Sendo o corte Lombo separado para dissecção e determinação das proporções de músculo, osso, gordura e outros componentes. O músculo Longissimus lumborum foi também separado para avaliação da maciez. O sistema de alimentação alterou as características da carcaça de caprinos, e os animais alimentados com leite até o abate apresentaram melhor rendimento de carcaça e melhor qualidade da carne. O cruzamento do grupo racial Boer com o Alpino aumentou a proporção de tecido muscular depositado, caracterizando dessa forma uma carcaça de melhor qualidade, mas a maciez da carne não foi influenciada pelo grupo racial e sistema de alimentação. O grupo racial também influenciou nas características de carcaça, sendo recomendada a participação da raça Boer até 3/4, já que acima disso, além de não melhorar o índice de compacidade e a conformação da carcaça, reduz o rendimento da perna. O sistema de alimentação com leite antecipa a deposição de gordura total, que pode beneficiar a qualidade da carcaça, tendo em vista a escassez de gordura na carcaça de caprinos.UEL2018-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionHypothetical and deductiveHypothetical and deductiveapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3051710.5433/1679-0359.2018v39n4p1759Semina: Ciências Agrárias; Vol. 39 No. 4 (2018); 1759-1774Semina: Ciências Agrárias; v. 39 n. 4 (2018); 1759-17741679-03591676-546Xreponame:Semina.
