对河南省安阳市龙安区农家宝养猪场2012-2014年204胎次长大二元母猪各胎产仔数、初生个体均重等数据进行统计，探讨不同胎次和配种季节对长大二元母猪繁殖性能的影响。结果表明：胎次对母猪产仔性能影响较大，其产仔数、初生个体均重和断奶个体均重以第1~2胎次低，随着胎次增加，繁殖性能逐步上升，至第6胎次达到高峰，此后逐渐下降；春季配种母猪的繁殖性能明显优于其它三季。
對河南省安暘市龍安區農傢寶養豬場2012-2014年204胎次長大二元母豬各胎產仔數、初生箇體均重等數據進行統計，探討不同胎次和配種季節對長大二元母豬繁殖性能的影響。結果錶明：胎次對母豬產仔性能影響較大，其產仔數、初生箇體均重和斷奶箇體均重以第1~2胎次低，隨著胎次增加，繁殖性能逐步上升，至第6胎次達到高峰，此後逐漸下降；春季配種母豬的繁殖性能明顯優于其它三季。

The parities and litter sizes of 204 litters of piglets from 2012 to 2014 in Nongjiabao Pig Farm in Long'an District of Anyang city were investigated to study the reproductive performance of Landrace×Yorkshire sow according to the parities and hybridization seasons .The results showed that the parity has a greater effect on litter size,with the lower litter size performance at the first and second parity,and later rising with more parities.It arrives at its peak at 6th parity and then falling.The mating seasons strongly influence the reproductive performance,the best for the sows hybridized in spring.
