摘　　要：该研究旨在分析非遗传因素对超细型细毛羊初生重的影响。收集了新疆塔城种羊场2014-2017年共2042只新生超细毛羊初生重,运用SAS9.2软件GLM程序分析了配种月份、性别、产羔月份、产羔类型和出生年份对超细型细毛羊初生重的影响。结果表明:出生年份、性别、产羔类型对超细型细毛羊初生重呈现极显著影响(P<0.01);产羔月份、配种月份对超细型细毛羊初生重影响不显著(P>0.05)。由此可见,在未来育种工作中应综合考虑出生年份、性别、产羔类型这3个因素,为后期估计超细型细毛羊主要经济性状提供参考,并为新疆超细型细毛羊的育种工作提供全面、准确的参考。The purpose of this study was to analyze the effects of non-genetic factors on the birth weight of 2042 new-born superfine wool sheep in Xinjiang Tacheng sheep farm from 2014 to 2017.The effects of breeding month,sex,lambing month,lambing type and year of birth on birth weight of new-born superfine wool sheep in Tacheng sheep farm were analyzed by SAS9.2 software GLM program.The results showed that year of birth,sex and lambing type had a highly significant effect on birth weight(P<0.01),while lambing month and breeding month had no significant effect on birth weight(P>0.05).It can be seen that the three factors,year of birth,sex and lambing type,should be taken into consideration comprehensively in future breeding so as to provide reference for the estimation of main economic traits of superfine Merino sheep in the later stage,and provide comprehensive and accurate reference for the breeding of Xinjiang Superfine wool sheep.
