Resumo: This study evaluated the weight gain (ADG), feed conversion (FC), feed efficiency (FE), characteristics of carcass and retail cuts of Santa Inês sheep fed different levels of metabolizable energy (2.08, 2.28, 2.47 and 2.69 Mcal kg-1 of DM). Twenty lambs, with age and mean body weight of 50 days and 13 &plusmn; 0.56 kg, respectively, were distributed in randomized block design with five replications. We verified a linear increase effect (p < 0.05) on the ADG. The loss at fasting, FC, FE, hot and cold carcass dressing, as well as the weight loss by cooling were not affected (p > 0.05) by the energy levels of the rations. Nevertheless, the weights of hot and cold carcass and theempty body , expressed in kg, presented quadratic effect (p < 0.05), as we increase the levels of metabolizable energy in experimental diets. The energy levels influenced the yield of rib and shoulder, as the loin eye area (p < 0.05). In conclusion, the manipulation of the energy level of the ration changes the ADG, the hot and cold carcass weight, the shoulder yield, the rib weight and the loin eye area of Santa Ines sheep.

Vinte cordeiros, com idade e peso corporal médio de 50 dias e 13,00 &plusmn; 0,56 kg, respectivamente, foram distribuídos em blocos casualizados, com cinco repetições. Verificou-se efeito linear crescente (p < 0,05) sobre o GMD. A perda ao jejum, CA, EA, rendimentos de carcaça quente e fria, bem como a perda por resfriamento não foram influenciados (p > 0,05) pelos níveis energéticos das rações. No entanto, os pesos de carcaça quente e fria, e o peso do corpo vazio, expressos em kg, apresentaram efeito quadrático (p < 0,05) à medida que se aumentaram os níveis de energia metabolizável nas rações experimentais. Conclui-se que a manipulação do nível energético das rações altera o GMD, o peso da carcaça quente e fria, o rendimento da paleta, o peso da costela e a área de olho de lombo em ovinos Santa Inês.Editora da Universidade Estadual de Maringá2010-10-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de campoapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/968410.4025/actascianimsci.v32i4.9684Acta Scientiarum.
