Resumo: | The objective of this study was to evaluate the effect of finishing systems on natural pasture and gender on the carcass quality, parts and tissue development of lambs. Forty-five non-castrated males and forty-five females were distributed in a completely randomized design into three treatments: lamb with mother kept on pasture; weaned lamb kept on pasture and weaned lamb kept on pasture with supplementation (soybean hulls at 1% of body weight). The criteria for slaughter was body condition score (2.0 - 3.0). The carcass characteristics and parts composition were influenced by the sex. The finishing system with supplementation promoted greater carcass yield and longer leg length. The tissue composition was different only for the sex, with the males presenting bigger amount of muscle mass. The allometric growth of shoulder of supplemented lambs and the shoulder and leg of the lambs with mother had been precocious, while the ribs of the supplemented lambs and lambs with the mother were late and the other components had growth similar to the half-carcass. For the females, only shoulder of lambs finished with mother presented precocious growth, being isogonic for the other cuts. The finished systems evaluated demonstrated that Texel × Corrierdale lambs slaughtered with similar body condition score present similar carcass quality. The development is influenced by the termination system and sex. The quali-quantitative characteristics of the carcass were influenced by the sex. The development of the regional components of the males are influenced by the finishing system. Nevertheless, the tissu components are not influenced by the finishing system or gender. |

The objective of this study was to evaluate the effect of finishing systems on natural pasture and gender on the carcass quality, parts and tissue development of lambs. Forty-five non-castrated males and forty-five females were distributed in a completely randomized design into three treatments: lamb with mother kept on pasture; weaned lamb kept on pasture and weaned lamb kept on pasture with supplementation (soybean hulls at 1% of body weight). The criteria for slaughter was body condition score (2.0 - 3.0). The carcass characteristics and parts composition were influenced by the sex. The finishing system with supplementation promoted greater carcass yield and longer leg length. The tissue composition was different only for the sex, with the males presenting bigger amount of muscle mass. The allometric growth of shoulder of supplemented lambs and the shoulder and leg of the lambs with mother had been precocious, while the ribs of the supplemented lambs and lambs with the mother were late and the other components had growth similar to the half-carcass. For the females, only shoulder of lambs finished with mother presented precocious growth, being isogonic for the other cuts. The finished systems evaluated demonstrated that Texel × Corrierdale lambs slaughtered with similar body condition score present similar carcass quality. The development is influenced by the termination system and sex. The quali-quantitative characteristics of the carcass were influenced by the sex. The development of the regional components of the males are influenced by the finishing system. Nevertheless, the tissu components are not influenced by the finishing system or gender. |
