摘　　要：为研究不同初配日龄对大白母猪繁殖性能的影响。试验选择1538头初配日龄在180~300 d的大白母猪5974条繁殖记录,初配日龄以30 d为单位,划分为4个试验组后进行单因素方差分析。结果显示:母猪初配日龄在210~240 d的产活仔数显著高于初配日龄为180~210 d的母猪(P<0.05),而断奶窝重显著高于初配日龄为270~300 d的母猪(P<0.05),前3胎次的总产仔数显著高于初配日龄为240~270 d和270~300 d的母猪(P<0.05),前3胎次和前6胎次的断奶窝重均显著高于270~300 d的母猪(P<0.05),且其利用胎次显著高于180~210 d的母猪(P<0.05)。试验结果表明,初配日龄210~240 d的母猪具有最佳的繁殖性能。To study the effects of different first mating age on reproductive performance in Yorkshire sows,5974 breeding records of 1538 Yorkshire Sows of first mating aged from 180 to 300 days were analyzed in this study.Taking 30 days as the division of first mating age,the sows were divided into 4 experimental groups and one-way ANOVA was used.Results showed that sows with the first mating age at 210~240 d had significantly higher NBA than those at 180~210 d(P<0.05),whose weight of weaning litter was significantly higher than those at 270~300 d(P<0.05),TNB for the first three parity sows was significantly higher than those at 240~270 d and 270~300 d sows(P<0.05),the weight of weaning litter for the first three parities and six parities were significantly higher than those of 270~300 d sows(P<0.05),the utilized parities were significantly higher than those of 180~210 d sows(P<0.05).In conclusion,Yorkshire sows with the first mating age of 210~240 d have best reproductive performance.
