以小尾寒羊（母本）为对照,对4、6、8、12月龄的巴美肉羊（父本）和杂交后代巴寒F1美肉的生长发育和屠宰性能进行测定。结果表明：巴美肉羊胸围、胸围指标和体躯指数极显著大于小尾寒羊（P〈0.01）;巴美肉羊和巴寒F1日增质量在8月龄达到最大,12月龄开始下降。巴美肉羊和巴寒F1的屠宰性能和等级分割肉优于小尾寒羊。在6月龄巴寒F1净肉率、肉骨比和腰肉显著大于小尾寒羊（P〈0.05）,说明巴寒F1具有早期生长优势。随月龄的增加,巴美肉羊净肉质量、胴体产肉率、净肉率、肉骨比、肋肉和腹下肉极显著大于小尾寒羊（P〈0.01）,腰肉差异显著（P〈0.05）。在12月龄巴寒F1的屠宰率和净肉率极显著大于小尾寒羊（P〈0.05）。但各个月龄宰前活质量和胴体质量的差异不显著（P〉0.05）。

The growth and slaughtering performances of Bamei mutton sheep,Small Tail Han sheep（♀） and F1 hybrid between male Bamei mutton sheep and female Small Tail Han sheep at 4,6,8 months and 12 months of age were comparatively analyzed.The results showed that Bamei mutton sheep were significantly higher than Small Tail Han sheep in chest circumference,chest circumference index and trunk index（P0.01）.The daily weight gain of Bamei mutton sheep and F1 hybrid showed its maximum value at 8 months of age,and began to decrease at 12 months and the slaughtering performance and the weight of mutton cuts of different grades were better than those of Small Tail Han sheep.At 6 months of age,F1 hybrid revealed a significant increase in pure meat percentage,meat-to-bone ratio and loin meat compared with Small Tail Han sheep（P0.05）,thus suggesting F1 hybrid has early growth dominance.With increasing age,the pure meat percentage,carcass meat percentage,meat-to-bone ratio,pure meat percentage,meat-to-bone ratio rid meat and belly meat of Bamei mutton sheep became highly significantly higher than those of Small Tail Han sheep（P0.01） and the difference in loin meat was significant（P0.05）.At 12 months of age,carcass percentage and pure meat percentage were significantly higher in F1 hybrid compared with Small Tail Han sheep（P0.05）.However,pre-slaughtering weight and carcass showed no significant differences among sheep at various months of age（P 0.05）.
