本研究旨在通过对屠宰性能、肌肉化学成分的检测，探讨杜泊羊与小尾寒羊杂交对后代屠宰性能及肉品质的影响，为选育优质肉羊品种提供理论依据。结果表明：从屠宰性能来看，杜寒F1和杜寒F2均继承了杜泊羊的优点，对小尾寒羊产肉率低的缺点有较大改善；从总体肉品质来看，杜寒F1和杜寒F2均继承了杜泊羊产肉多、肉质鲜美的优点，并且在肉色、嫩度、熟肉率、滴水损失、含钙量方面均优于小尾寒羊和杜泊羊。杜寒F2的肌肉嫩度、肉色指标均优于杜泊羊、小尾寒羊及F1代。

The aim of this research is to explore the influence of hybrid offspring between Dor-per sheep and Small Tailed Han sheep on the slaughtering performance and mutton flavor by the de-tecting the slaughter characteristics and chemical composition of muscle, in order to provide a theoretical basis for the breeding selection of sheep.The results showed that: ① For the slaugh-ter performance, D-H F1 and D-H F2 have inherited the advantages of Dorper sheep, greatly improv-ing the low rate of meat production of Small Tailed Han sheep. ② For the overview of meat quali-ty, D-H F1and D-H F2 have inherited the advantages from Dorper sheep with high production and high quality of meat. And flesh, tenderness, cooking loss, drip loss, calcium concentration are all bet-ter than Small Tailed Han sheep and Dorper sheep. The muscle tenderness, flesh color indicators of D-H F2 are better than Dorper sheep, Small Tailed Han sheep and D-H F1.
