摘　　要：【目的】探究主要非遗传因素对中国美利奴羊(新疆型)14月龄鉴定性状的影响,收集9 942条母羊鉴定记录。【方法】利用SAS(8.1)软件的GLM程序,分析了鉴定时年份和群别对被毛性状、剪毛性状、体型外貌、品种等级评分和鉴定时体重等性状的影响。【结果】鉴定时年份和群别对头毛评分、毛长度、毛密度评分、毛细度评分、剪毛后体重、剪毛量、体型外貌评分、品种等级评分、鉴定时体重均有极显著影响(P<0.01)。【结论】在估计中国美利奴羊(新疆型)遗传参数和育种值时,鉴定时年份和群别可以作为固定效应放到模型中。[Objective] The objective of this study was to investigate the effect of main nongenetic factors on 9 traits in Chinese merino sheep （Xinjiang type） based on 9 942 tested records of dam. [Method] The effect of main non - genetic factors （ including the measuring year and group ） was analyzed on covered wool trait, shearing trait,body condition score, breed grade and measuring weight by least squares means with SAS （8.1） program. [Result] The results showed that the effect of measuring year and group was highly significant （ P 〈 0.01 ） for capilli score, staple length , wool density score, wool fineness score, live weight after shearing, greasy weight, body condition score, breed score and measuring weight. [ Conclusion] These results indicated that the measuring year and group can be used as fixed effects in models when predicting genetic parameters and estimating breeding value of Chinese merino sheep （Xinjiang type） .
