摘要
对４６５头母猪、１０６４胎次的繁殖性状进行了统计分析．结果表明，４—１０胎次的母猪繁殖性能明显优于其他胎次（Ｐ＜０．０５）．夏季高温季节对母猪繁殖性能的影响，表现为产仔数的减少（Ｐ＜０．０５）和仔猪的初生重降低（Ｐ＜０．０５）．母猪的乳头数与其产仔数、产活仔数、断奶头数、断奶窝重和仔猪乳头数均呈显著正相关．仔猪乳头数不受母猪胎次的制约。
Correlation of some reproductive performance of sow was sdutied among 465 sows and 1064 nets.The results showed that the reproductives in 4-10 pregnant times of sows are obviously higher than that in other pregnant times (P<0. 05). The litter size and birth weight of baby pigs are significantly decreased by high temperature in summer season (P<0.05).Significant positive correlations exist between nipple number of sows and litter size, piglet born alive, litter size at weaning, weight of weaning litters and number of nipple of baby pigs. Pregnant times have no obviously effect on number of nipple of baby pigs.
