为研究胎次、配种季节对大约克母猪繁殖性能的影响，运用SPSS 16.0软件对753窝大约克纯种母猪的产仔数、出生窝重和断奶窝重等进行比较分析。结果表明：产总仔数第8胎最高（15.25头），与第1胎差异显著（P＜0.05），总的呈现随胎次增加而上升的趋势。大约克母猪春季和冬季配种产总仔数与秋季差异显著（P＜0.05）；冬季配种母猪的出生窝重、断奶均重、断奶窝重均高于其他三季。

To investigate the effect of parities and mating seasons on the reproductive perfor-mance of Yorkshire sow, litter size, litter birth weight and weaning weight of Yorkshire sows (753) were comparative analysised by SPSS 16.0 software. The result showed that parities signifi-cant effect the litter size(P<0.05). This characteristics have an upward tendency with parities. Titter size and piglets of spring and winter breeding sows was significant different to autumn(P<0.05);Litter birth weight, weaning weight of winter breeding sows is higher than other three sea-sons’.
