摘　　要：以179头法系大约克母猪1008窝次的生产繁殖成绩为研究对象,分析母猪的初生重、出生胎次、出生同窝活仔数和配种日龄对其终身生产力的影响。结果表明,母猪的初生重对终身断奶仔猪数、终身断奶窝重影响显著。其中,母猪初生重在1.1~1.3 kg之间的1组终身断奶仔猪数最多为67.54头,分别比2组、3组母猪显著提高12.49%(P<0.05)、16.67%(P<0.05);终身断奶窝重也以1组最高为423.14 kg,分别比2组、3组显著提高13.48%(P<0.05)、16.64%(P<0.05)。母猪的出生胎次、同窝活仔数和配种日龄对其终身断奶仔猪数、终身断奶窝重影响都不显著。大约克母猪的初生重、出生胎次、出生同窝活仔数和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,母猪初生重与出生同窝活仔数极显著负相关,偏相关系数为-0.497,出生胎次与出生同窝活仔数显著正相关,偏相关系数为0.170,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0.994,其他指标间相关性不显著。In the study,reproduction performance data coming from 1008 litters of 179 French Yorkshire sows were collected,and the effect of birth weight,parity,number of live litters born and mating age on sow lifetime productivity were analyzed.The results showed that the effects of sow birth weight on sow lifetime number of piglets weaned and lifetime weaning litter weight were significant.The number of lifetime weaned piglets in the first group with a sow weight between 1.1-1.3 kg was up to 67.54,compared with the second group and the third group,which increased by 12.49%(P<0.05)and 16.67%(P<0.05)respectively.Lifetime weaning litter weight in the first group was 423.14 kg,compared with the second group and the third group,which increased by 13.48%(P<0.05)and 16.64%(P<0.05)respectively.The effects of sow 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 correlation analyses indicated that among sow 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. Sow birth weight and number of live litters born were significantly negative correlated, the partial correlation coefficient was -0.497. Sow parity and number of live litters born were significantly positive correlated, the partial correlation coefficient was 0.170. Lifetime number of piglets weaned and lifetime weaning litter weight were extremely significantly positive correlated, the partial correlation coefficient was 0.994, and the correlation between other indicators is not significant.
