| 摘 要： | 对河南省某原种猪场2002～2004年270窝法系大约克母猪各胎产仔数进行统计，根据不同胎次、不同配种月份分别研究法系大约克母猪的繁殖性能。结果表明：胎次对产仔数的影响较大，其产仔数性能以第一胎低，随胎次增加，繁殖性能逯步上升，至第五胎达到高峰，此后逯渐下降；配种月份对其繁殖性能的影响不大，但以10月份配种的母猪繁殖性能最差。

| Abstract: | The parities and litter sizes of 270 litters of French York piglets from 2002 to 2004 in a breeding farm in Henan province were investigated to study the reproductive performance of French York sows according to the parities and hybridization months.The results showed that the parity has a greater effect on litter size,with the lower litter size performance at first parity,and later rising with more parities.it arrives at its peak at 5th parity and then falling.The mating months do not strongly influence the reproductive performance,but the worst for the sows hybridized in October. |
