摘　　要：以128头法系长白母猪560窝次的生产繁殖成绩为研究对象,分析母仔猪的出生体重、出生胎次、出生同窝活仔数、配种日龄对其终身生产力的影响。结果表明,长白母仔猪的出生体重、出生胎次、出生同窝活仔数和配种日龄对终身断奶仔猪数、终身断奶窝重影响均不显著(P>0.05)。其中,Ⅱ组母仔猪的出生体重在1.3~1.5 kg之间,其终身断奶仔猪数最高为50.45头,分别比Ⅰ、Ⅲ组母仔猪提高6.79头、4.52头,Ⅲ组母猪终身断奶仔猪数为45.93头,比Ⅰ组提高2.27头,差异不显著(P>0.05)。终身断奶窝重也以Ⅱ组最高,为315.06 kg,分别比Ⅰ组、Ⅲ组提高16.74%、9.07%,Ⅲ组终身断奶窝重为288.85 kg,比Ⅰ组提高7.03%,差异不显著(P>0.05)。长白母仔猪的出生体重、出生胎次、出生同窝活仔数、配种日龄与终身生产力的相关性分析表明,偏相关系数有正有负,相关强度有大有小。其中,长白母仔猪的出生体重与出生胎次极显著正相关,偏相关系数为0.269(P<0.01);与出生同窝活仔数极显著负相关,偏相关系数为-0.424(P<0.01);母猪产仔胎数与终身断奶仔猪数极显著正相关,偏相关系数为0.235(P<0.01),终身断奶仔猪数与终身断奶窝重极显著正相关,偏相关系数为0.965(P<0.01),其他指标间相关性不显著。In the study,reproduction performance data came from 560 litters of 128 French Landrace sows,and the effect of birth weight,birth parity,number of live litters born and mating age on sow lifetime productivity were analyzed.The results showed that the effected of sow piglet birth weight,parity,number of live litters born and mating age on sow lifetime number of piglets weaned and lifetime weaning litter weight were not significant.The number of lifetime weaned piglets in the groupⅡwith a sow weight between 1.3~1.5 kg was the highest up to 50.45 pigs,compared with the groupⅠand groupⅢ,which increased by 6.79(>0.05)and 4.52(>0.05)respectively.The number of lifetime weaned piglets in groupⅢwas up to 45.93 pigs,which was higher than that of the groupⅠby 2.27(>0.05).Lifetime weaning litter weight in the groupⅡwas 315.06 kg,compared with groupⅠand groupⅢ,which increased by 16.74%(>0.05)and 9.07%(>0.05)respectively.Lifetime weaning litter weight in groupⅢwas 288.85 kg,compared with the groupⅠwhich in creased by 7.03%(>0.05).The correlation indicated that among sow piglit birth weight,parity,number of live litters born,mating age and lifetime productivity,some partial correlation coefficients were positive,and some were negative.Some correlation coefficients were large,and some were small.The landrace sow piglet birth weight and birth parity were extremely significantly positive correlated,the partial correlation coefficient was 0.269(<0.01).The landrace sow piglet birth weight and number of live litters born were extremely significantly negative correlated,the partial correlation coefficient was-0.424(<0.01).The landrace sow piglet number of litters and lifetime number of piglets weaned were extremely significantly positive correlated,the partial correlation coefficient was 0.235(<0.01).Lifetime number of piglets weaned and lifetime weaning litter weight were extremely significantly positive correlated,the partial correla tion coefficient was 0.965(<0.01),and the correlation between other indicators w
