安哥拉山羊与本地山羊杂交试验

Hybrid Test of Angora goat and local goat

利用安哥拉山羊与当地土种山羊进行杂交改良 ,产绒量比本地羊增加两倍以上 ,有髓毛减少 ,绒毛增多。杂种羊具有耐粗饲、抗病力强 ,生长发育相对快等杂种优势。试验组比对照组成活率提高 4 16个百分点 ,繁活率提高 4 44个百分点。

A hybridization test of native goat with Angora goat was conducted.The results showed that the production of downy wool of the hybrid goat increased two times more than that of native goat.There were the less medullated fiber and more downy wool in the hybrid goat.The hybrid goat appeared the hybrid vigor such as endurance of extensive feeding and mangement,strong sesistance to disease and relatively fast growth and development.The survival rate of goat in the test group increased 4.16 percent poiuts and.the reproduction survival rate increased 4.44 percent points than those in the control group.
