摘　　要：本文旨在对比研究电子母猪群养系统(ESF)与限位栏系统对杜洛克猪、大白猪和长白猪繁殖性能的影响。试验选取河南某公司2个种猪场2013年各品种主要繁殖性能记录数据,且2个种猪场分别采用限位栏系统和ESF系统。试验结果表明:不同品种ESF系统下,弱仔数、死仔数、木乃伊数和畸形数等均低于限位栏系统,初生窝重以及平均初生重均高于限位栏系统,且差异极显著(P<0.01);此外,两种饲养管理系统下,妊娠母猪妊娠阶段确认妊娠后,妊娠性能指标(空怀、流产、返情、淘汰、死亡以及肢蹄损伤等)的比例均差异不显著,但从总体比例差值可以看出ESF系统优于限位栏系统。结论认为,ESF系统母猪繁殖性能指标整体优于限位栏系统,且妊娠期母猪异常状况的发生率有所降低,提高母猪的繁殖性能。The study was to compare the impact ofelectronic sow feeding system（ESF） and crates system on reproductive performance of Duroc, Yorkshire and Landrace. We uesd two major reproductive performance data of2013 in a Henan company,and the two farms were used crates system and ESF system. The results showed that： the number of weak litter, stillborn, mummy count and abnormal piglets of ESF system was significantly under crates system（P0.01）, the mean birth weight of ESF system was significantly higher than crates system（ P0.01）. In addition,both feeding and management systems, pregnant sows in gestation stage to confirm pregnancy, pregnancy performance indicators： Empty pregnant, abortion, return to estrus, week out, death and the proportion of limb hoof injury were not significantly different, but the overall proportion of ESF system was lower than crates system. Conclusion： ESF system is better than crates system at whole criteria and the incidence of abnormal conditions during the pregnant decreased.In belief, ESF canimprove the reproductive performance of sows.
