青海高原型藏羊毛纤维物理性能分析

Analysis of Physical Properties of Wool Fiber from Plateau Type of Tibetan sheep in Qinghai

对1993年和2006年青海高原型藏羊毛纤维物理性能的测定结果进行了比较,并分析了产生差异的原因。结果:2006年成处公、母藏羊粗毛在被毛中重量比非常显著的少于1993年的测定结果(P<0.01),而死毛含量显著地增加;两型毛和粗毛的细度非常显著的小于1993年(P<0.01)。2006年测定的成年母羊两型毛和粗毛的毛纤维伸直长度非常显著的短于1993年(P<0.01)。

The measurement results of physical properties of wool faber from plateau type of Tibetan sheep in Qinghai Province in 1993 and 2006 were compared and the cause of measurement result difference was analysed. The results showed that in 2006, the gravimetrie ratio of coarse hair in hair coat of adult ram and ewe Tibetau steep was very significantly decreased than the results measured in 1993 （ P 〈 0.01 ） and the content of kemp hair of them was very significantly iacreased than that in 1993（ P 〈0.01 ） ,The fineness of heterotypical fiber and coarse hair of them was very significantly sinaller than that in 1993 （ P 〈 0.01 ） and the stretched Length of wool fiber measured in 2006 for heterotypieal fiber and coarse hair of adult ewe was very significantly shorter than that in 1993 （P 〈 0.01 ）.
