摘要:

为合理开发利用天祝白牦牛被毛纤维,用光学显微镜与扫描电子显微镜相结合的方法,对天祝白牦牛被毛各类型纤维的组织结构和超微结构进行观察研究。结果表明:天祝白牦牛身体不同部位的绒毛和两型毛纤维组织结构和超微结构基本相似,不同部位粗毛纤维的组织结构存在一定的差异,特别是髓质层结构差异较大。不同类型纤维鳞片层结构有所差异,鳞片密度排序为粗毛>两型毛>绒毛,且绒毛与粗毛差异极显著(P<0.01);鳞片高度和厚度的变化均为绒毛>两型毛>粗毛,且绒毛与粗毛间差异显著(P<0.05)。

Abstract:

In order to reasonably develop the hair of Tianzhu White yak, the article studied organizational structure and ultrastructure of Tianzhu white yak by optical microscopy and scanning electron microscopy. The results indicted that in respect to organizational structure and ultrastructure,the heterotypical hair and fuzz hair in different parts of the Tianzhu white yak body are similar, while there exist some differences in organizational structure of coarse hair fibers in different parts of the body, in particular, the structure of the medullated fibers. The scale layer structure of different types of fiber varies and the scale density is coarse hair > heterotypical hair > fuzz hair, and significant difference (P <0.01) exists between the fuzz hair and coarse hair. As to the change of scale height and thickness:fuzz hair> heterotypical hair > coarse hair, and significant difference(P <0.05) exhibits between the fuzz hair and the coarse hair.
