Abstract 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）.
