为了改善与提高中国美利奴羊(新疆型)的肉用性能,采用夏洛莱公羊、白萨福克公羊与中国美利奴羊(新疆型)母羊进行杂交试验,并对其F1的初生重、3月龄重、6月龄重、剪毛后体重、剪毛量、羊毛细度等性状进行了测定.结果表明,白萨福克公羊×中国美利奴母羊(新疆型)F1(白中F1)、夏洛莱公羊×中国美利奴母羊(新疆型)F1(夏中F1)2组之间的初生重、3月龄重和剪毛后重差异均不显著(P＞0.05)；而夏中F16月龄重,则比白中F1高4.5％(P＜0.01)；2组之间毛纤维直径差异不显著(P＞0.05),毛长和剪毛量差异均极显著(P＜0.01),夏中F1的剪毛量比白中F1高9.8％.说明在新疆伊犁地区,夏中组合较白中组合更适合用作肥羔生产,而且从毛用性能方面看,夏中组合也较白中组合更具优势.%In order to improve and enhance the fine-wool sheep's meat performance,the crossbreeding of Charolais and White Suffolk rams with the Chinese Merino sheep(Xinjiang type)were carried on,and the birth weight ,3-month-old's body weight , 6-month-old' s body weight, after-shearing body weight, shearing quantity and wool fineness of their hybrid F, ewes were compared. The results showed that the differences of the two groups's birth weight,3-month-old's body weight and after-shearing body weight were not significant (P>0.05);the 6-month-old ' s body weight of the Charolais xChinese Merino sheep (Xinjiang type)group was 4.5 % higher than that of the White Suffolk x Chinese Merino( Xinjiang type )group (P<0.05);the differences of wool length, wool fiber diameter between the two groups were not significant (P>0.05) , and the amount of shear wool of Charo-laisxChinese Merino sheep (Xinjiang type )group was higher by 9.8 % than that of White Suffolk xChinese Merino sheep (Xinjiang type)group (P<0.01).Therefore,it was concluded that,in the Ili region compared with the White Suffolk xChinese Merino sheep (Xinjiang type Combination, the Charolais xChinese Merino sheep (Xinjiang type )eombination was more suitable for fat lambs production,and on the wool performance aspect, the CharolaisxChinese Merino sheep (Xinjiang type) combi-nation also had more advantages.
