摘　　要：旨在建立一套促进母猪生殖健康、提升繁殖性能的技术方法。选择健康的长大二元母猪,随机分为对照组和试验组,对照组饲喂基础日粮,试验组饲喂基础日粮+每天每头猪300 mg原花青素。母猪断奶前1周开始进行原花青素的添加,直至断奶后2周,共21 d。结果:在断奶前1周至断奶后2周,在母猪日粮中连续添加原花青素,显著提高了窝均总产仔数(P<0.05),与对照组相比,试验组窝均总产仔数提高了1.33头。血液学指标测定表明,饲喂原花青素提高了母猪的抗氧化能力和免疫力,降低炎症反应,并对肝脏功能具有一定的改善效果。综上,日粮添加原花青素对母猪繁殖性能、血清生化指标、抗氧化能力及免疫功能都存在有益影响。This study aims to establish a technology to promote reproductive health and enhance the reprodactive performance of sows.Healthy crossbred(Landrace×Large White)sows were selected and randomly divided into a control group and a procyanidins supplementa⁃tion group.The control group was fed a basic diet,while the procyanidins supplementation group was fed the basic diet plus 300 mg of procy⁃anidins per pig per day.Procyanidins supplementation started one week before weaning and continued until two weeks after weaning,lasting a total of 21 days.Results:continuous addition of procyanidins to the sows diet from one week before weaning to two weeks after weaning sig⁃nificantly increased the total number of piglets per litter(P<0.05).Compared to the control group,the experimental group had an average increase of 1.33 piglets per litter.Hematological measurements indicated that procyanidins supplementation enhanced the antioxidant capacity and immune function of the sows,reduced inflammatory responses,and improved liver function to some extent.In conclusion,dietary supple⁃mentation with procyanidins had positive impacts on the reproductive performance,serum biochemical parameters,antioxidant capacity,and immune functions of sows.
