摘要
引进努比亚山羊在甘肃中部寒旱区进行饲养,仍表现出了生长速度较快,所产羔羊6月龄时公母羔体重分别为23.17 kg、21.6 kg,与原产地三等级公母羔羊体重基本相当。多胎高产的特性仍明显,引进后仍有四季发情特性,初产母羊产双羔母羊在80%以上。
The introduced Nubia goats were raised in the cold and arid regions of central Gansu and still showed a relatively fast growth rate.The weights of the male and female lambs were 23.17 kg and 21.6 kg respectively at the age of 6 months,which was basically the same as that of the three-grade male and female lambs in the origin.The characteristics of multiple births and high yield are still obvious.After the introduction,there are still four seasons of estrus,and more than 80%of primiparous ewes produce double lambs.
