阿勒泰羊肌肉组织的免疫组化分析

Immunohistochemistry Analysis of Muscles in Altay Mutton Sheep

[目的]比较阿勒泰羊肌肉组织肌球蛋白重链(Myosin heavy chain,My HC)I型肌纤维含量。[方法]收集8月龄阿勒泰羊、Texel羊和F1代肉羊肌肉组织,应用免疫组化方法分析阿勒泰羊My HC I型肌纤维含量,并与Texel和F1代肉羊进行了比较。[结果]阿勒泰羊My HC I型肌纤维含量与Texel肉羊、F1代肉羊差异显著(P<0.05)。[结论]研究结果可为肉羊品种选育和肌肉品质鉴定提供理论依据。

[Objective]To compare the MyHC I content in the muscles of Altay mutton sheep.[Method]The muscle samples were collected from8-month old Altay mutton sheep,Texel sheep and F1hybrid to analyze MyHC I content by using immunohistochemical method and compare it with Texel sheep and F1hybrid.[Result]MyHC I content in the muscles of Altay mutton sheep had significant differences with that in Texel sheep and F1hybrid(P<0.05).[Conclusion]The research results could provide theoretical basis for mutton sheep breeding and the identification of muscle quality.
