摘　　要：为探讨饲粮中可溶性纤维对妊娠后期母猪繁殖性能的影响,随机选择甘肃省成县某规模化养猪场的120头妊娠后期母猪,平均分为两组,对照组给予常规基础日粮饲喂,试验组给予基础日粮+1.0%可溶性纤维饲喂,比较分析饲粮中添加可溶性纤维对母猪繁殖性能的影响。结果表明,试验组母猪分娩率、平均产仔数、平均产活仔数、仔猪平均出生窝重、窝平均断奶头数、平均断奶仔猪重和平均断奶窝重等指标显著高于对照组(P<0.05);饲粮中添加可溶性纤维的试验组母猪初乳乳糖含量、蛋白含量均显著高于对照组(P<0.05);试验组母猪初乳体细胞数量显著低于对照组(P<0.05)。综上,可溶性纤维能够显著提高妊娠后期母猪的繁殖性能和改善母猪初乳品质,这为本地区母猪饲粮合理营养搭配和健康养殖提供相关参考。In order to explore the effects of soluble fiber in the late pregnancy diet on the reproductive performance of sows,a total of 120 late pregnancy sows from a large-scale pig farm in Cheng County,Gansu Province were randomly selected and divided into two groups.The control group was fed with conventional basic diet,while the experimental group was fed with basic diet+1.0%soluble fiber.The effect of adding soluble fiber to the diet on the reproductive performance of sows was compared and analyzed.The results showed that the delivery rate,average litter size,average live litter size,average litter weight,average weaned head count,average weaned piglet weight,and average weaned litter weight of the experimental group were significantly higher than those of the control group(P<0.05);the lactose and protein content in the colostrum of sows in the experimental group with soluble fiber added to the feed were significantly higher than those in the control group(P<0.05);the number of colostrum cells in the experimental group was significantly lower than those in the control group(P<0.05).In summary,soluble fiber could significantly improve the reproductive performance and colostrum quality of sows in the late pregnancy period,providing relevant reference for rational nutritional allocation and healthy breeding of sows in this area.
