摘要
试验选用2009—2012年中卫山羊羔羊的出生鉴定数据,研究非遗传因素(包括出生年份、性别、产羔季节和母羊胎次)对中卫山羊羔羊初生重的影响。结果表明,出生年份和性别对中卫山羊羔羊初生重的影响显著(P<0.05),而母羊胎次和产羔季节影响不显著(P>0.05)。
Based on the birth identification data of Zhongwei goats during 2009-2012,the effects of non-genetic factors （year of birth, sex, season of birth and maternal parity）on the birth weight of Zhongwei goat lambs were studied. The results showed that birth year and sex had significant effects on the birth weight of Zhongwei goat lambs （P〈0.05）and maternal parity and birth season had no significant effect on the birth weight of Zhongwei goat lambs （P〉0.05）.
