补饲硫对安哥拉山羊F_2代杂种羊无髓毛理化性能的影响研究

Study on Effects of Physical and Chemical Properties of Nonmedullar Fibers on Angora Goat Breed F2 Generation by Applying Supplementary Feeding of Sulphur in Treatment

用硫酸钠、胱氨酸对安哥拉山羊Ｆ２代杂种羊进行补饲。结果表明，二种硫源对Ｆ２代杂种羊无髓毛的伸直长度、强力、伸度及含硫量均有显著或极显著提高（Ｐ＜００５或Ｐ＜００１），对无髓毛的氨基酸总量、含硫氨基酸（胱氨酸）的含量也有提高。同时，二种硫源还提高了无髓毛纤维鳞片的可见高度，鳞片变亮变长，鳞片的角质缺损现象也减少。

Two sulphurous derivative sources,Na2SO3 and cystine,had been applied as supplementary feeds in use for Angora goat breed F2 generation.The results showed that,all targets of stretched length,strength,degree of elasticity and sulphur content of nonmedullar fibers in those treatment groups were significantly higher or much higher than those of the other comparative groups (P<005 or P<001).The total amount of amino acid,cystine content and visible height of nonmedullar fibers in two treatment groups had been shown in increase as well at the same time.Further on,the scale of nonmedullar fibers in two treatment groups had been shown to become somewhat broader and higher,and the scale of edge damages meantimely had also been shown in decrease from the view point in an adverse direction.
