摘　　要：[目的]探讨妊娠后期日粮中添加不同比例苜蓿草粉对母猪繁殖性能及血清生化、抗氧化和免疫指标的影响。[方法]采用单因子完全随机试验设计,将胎次、体况、预产期相近的40头妊娠后期大长母猪随机分为4组,每组10头。试验母猪日粮中分别添加0(对照组)、5%(5%苜蓿草粉组),10%(10%苜蓿草粉组)和15%(15%苜蓿草粉组)的苜蓿草粉。母猪确定妊娠85 d进入试验期,分娩后试验结束。妊娠第111天时,采集母猪血样,测定血清生化、抗氧化和免疫指标;母猪分娩12 h内,记录产仔数、产活仔数,测定仔猪初生窝重、初生个体重。[结果]10%苜蓿草粉组的仔猪初生窝重显著(P<0.05)高于其他处理组。10%苜蓿草粉组的血清白蛋白含量和白/球比显著(P<0.05)低于对照组;5%和10%苜蓿草粉组的血清葡萄糖含量显著(P<0.05)高于对照组。5%和10%苜蓿草粉组的血清总抗氧化能力显著(P<0.05)高于对照组;10%苜蓿草粉组的血清丙二醛含量显著(P<0.05)低于其他处理组;10%苜蓿草粉组的血清谷胱甘肽过氧化物酶活力显著(P<0.05)高于对照组;10%苜蓿草粉组的血清超氧化物歧化酶活力显著高于(P<0.05)其他处理组,5%和15%苜蓿草粉组的血清超氧化物歧化酶活力显著高于(P<0.05)对照组。10%苜蓿草粉组的血清IgM含量显著(P<0.05)高于5%苜蓿草粉组。[结论]妊娠后期日粮中添加苜蓿草粉对母猪的繁殖性能及血清生化、抗氧化和免疫指标有一定的改善作用,添加量以10%为宜。[Objective]To assess dietary supplementation of different proportions of alfalfa meal on reproductive performance and serum biochemical,antioxidant and immune indexes of sows during late gestation.[Method]Single-factor completely randomized block design was used in this study.According to the principle of similar parity,body condition and expected date of delivery,a total of 40 Yorkshire×Landrace sows in late gestation were randomly assigned into 4 groups with 10 individuals for each group.The basal diets of the experimental sows were supplemented with alfalfa meal at proportions of 0(control group),5%(5%alfalfa meal group),10%(10%alfalfa meal group)and 15%(15%alfalfa meal group),respectively.The formal experiment started on the 85th d of gestation and finished after delivery.On the 111th d of gestation,blood samples of the experimental sows were collected,and the serum biochemical,antioxidant and immune indexes were determined;the litter size and alive litter size of sows were recorded within 12 h of delivery,and the birth litter weight and birth individual weight of piglets were determined.[Result]The birth litter weight of piglets in 10%alfalfa meal group was significantly(P<0.05)higher than that in the remaining groups.The serum albumin content and albumin-globulin ratio in 10%alfalfa meal group were significantly(P<0.05)lower than those in control group,and the serum glucose contents in 5%and 10%alfalfa meal groups were significantly(P<0.05)higher than those in control group.5%and 10%alfalfa meal groups had significantly(P<0.05)increased serum total antioxidant capacity compared with control group;10%alfalfa meal group had significantly(P<0.05)decreased serum malondialdehyde content compared with the remaining groups;10%alfalfa meal group had significantly(P<0.05)elevated serum glutathione peroxidase activity compared with control group;10%alfalfa meal group had significantly(P<0.05)improved serum superoxide dismutase activity compared with the remaining groups,and 5%and 15%alfalfa meal groups had significa
