摘  要:
选择4、6、8月龄巴美肉羊各10只,与同月龄的小尾寒羊、苏尼特羊进行对比屠宰实验,分别测定并计算其体尺指标(体长、体高、胸围)、体尺指数(体型指数、胸围指数、体躯指数)和胴体等级分割肉质量,即一级肉(后腿肉和腰肉)、二级肉(肋肉和肩颈肉)、三级肉(腹下肉),确定巴美肉羊在生长发育和胴体等级肉产量方面是否具有优越性。结果表明:巴美肉羊的胸围、胸围指数和体躯指数均显著大于同月龄小尾寒羊和苏尼特羊(P<0.05),且随着月龄增加,该类指标的增加速率也快于对照组肉羊。同时,6、8月龄巴美肉羊的各等级肉质量均显著大于同月龄对照组肉羊(P<0.05),且随着月龄增加,其优质肉块的增长速率也大于其他肉块。因此,巴美肉羊与小尾寒羊和苏尼特羊相比,具有良好的前躯和躯干相对发育能力以及该品种肉羊良好的优质肉块的产肉性能。

摘  要:
To explore the superiority of Bamei mutton sheep in terms of growth and development,carcass grade and meat yield,Bamei sheep,Small Tail Han sheep and Sunit sheep of the same age(4,6 and 8 months,10 sheep in each age group) were compared for differences in body size indicators(body length,standing height and chest measurement),body measurement indexes(body mass index,chest index and body hindquarter index) and the weight of different mutton cuts(grades): grade 1(hind leg and loin),grade 2(rib and shoulder & neck) and grade 3(flank).Bamei sheep were found to have significantly larger chest measurement,chest index and body hindquarter index than Small Tail Han sheep and Sunit sheep of the same age(P<0.05),and these parameters increased faster with increasing age when compared to control group.The weight of three mutton grades from Bamei sheep at each age was significantly higher than that of control group of the same age(P<0.05),and the weight of quality mutton cuts increased faster than other mutton cuts with increasing age.Hence,Bamei mutton sheep is superior to Small Tail Han sheep and Sunit sheep in terms of body development and meat quality.
