| 摘 要： | 目的]为了探讨主要非遗传因素对中国美利奴羊(新疆型)羔羊初生重的影响,收集2×104条中国美利奴羊(新疆型)羔羊鉴定记录.方法]利用SAS8.1软件的GLM程序,分析出生类型、性别、群别、出生年以及月份对中国美利奴羊(新疆型)羔羊初生重的影响.结果]公母羔的平均初生重分别为3.609和3.501 kg; 性别对羔羊初生重有极显著影响(P＜0.01);产羔数对羔羊初生重也有极显著影响(P＜0.01),单羔的初生重高于双羔.群别和出生年对羔羊初生重也存在着极显著影响(P＜0.01);出生月份对羔羊初生重无显著影响(P＞0.05).结论]分析大量的记录资料讨论了出生类型等5个非遗传因素对中国美利奴羊羔羊(新疆型)初生重的影响,以期为今后估计美利奴羊遗传参数和育种值时固定效应的划分和选育提供一定的依据.

| Abstract: | 【Objective】This study was carried out to discuss the influence of non-genetic factors the lamb birth weight collected from 2 million sheep identification record.【Method】The Effect of non-genetic factors such as birth type,birth sex,group,birth year and birth month on the birth weight of Chinese merino sheep(Xinjiang type) was studied form 1999 to 2008.In this study,a total number of 11,893 records were analyzed by use of GLM procedure in SAS(8.1)software.【Result】 The statistical analysis indicated that the average birth weight between male lambs and female lambs were 3.609 and 3.501 respectively.The influences of birth sex on lambs birth weight were significant(P<0.01).The influences of the number of lambs on birth weight also was significant(P<0.01),and the birth weight of single lamb was higher than that of double lamb.The influence of birth month on birth weight was not significant(P>0.05).【Conclusion】The influence of 5 non-genetic factors on Chinese merino sheep(Xinjiang type)to provide the key basis for estimating merino sheep genetic parameters and breeding value fixed efficient of breeding value. |
