摘　　要：文章旨在研究日粮中添加发酵怀山药皮对母猪繁殖性能及哺乳期仔猪生产性能的影响。试验将99头胎龄一致的经产妊娠母猪随机分为3组,分别为I组(空白对照组)、Ⅱ组(2.5%发酵山药皮组)、Ⅲ组(5%发酵山药皮组),每组33个重复,每个重复1头母猪,试验期为妊娠85d至断奶后10d,共计65d。结果显示:(1)与I组相比,Ⅱ、Ⅲ组母猪产程、断奶发情间隔时间显著缩短(P <0.05),便秘率、平均窝产白胎数显著降低(P <0.05),采食量、断奶后10d内发情率显著提高(P <0.05)。(2)与I组相比,Ⅱ、Ⅲ组窝重、平均个体重、25d断奶重、平均日增重均有所提高,但差异不显著(P> 0.05);Ⅱ、Ⅲ组仔猪腹泻率显著低于I组(P <0.05)。(3)血清抗氧化指标:Ⅲ组仔猪血清相比I、Ⅱ组CAT、SOD、GSH-Px水平显著提高(P <0.05);与I组相比,Ⅱ、Ⅲ组母猪血清CAT、SOD、T-AOC水平均显著提高(P <0.05),血清MDA水平有所降低,但无显著差异(P> 0.05)。(4)Ⅱ、Ⅲ组产气荚膜梭菌数量显著低于I组(P <0.05);Ⅱ、Ⅲ组双歧杆菌、乳酸杆菌数量虽有提高但差异不显著(P> 0.05),沙门氏菌、大肠杆菌数量有所下降,差异不显著(P> 0.05)。结论 :母猪日粮中添加发酵怀山药皮可降低母猪便秘率,提高母猪机体抗氧化能力,减少母猪哺乳阶段体重损失,缩短产程,提升母猪繁殖性能及仔猪哺乳期的生长性能;母猪日粮中发酵怀山药皮以2.5%添加水平为宜。The purpose of this experiment is to investigate the effect of adding fermented dioscorea opposital skin to the diet on the reproductive performance of sows and the production performance of Suckling piglets.99 pregnant sows of the same gestational age were selected for the experiment and randomly divided into 3 groups:Group I(blank control group),GroupⅡ(2.5%fermented dioscorea opposita skin group),and GroupⅢ(5%dioscorea opposita skin group).Each group has 33 replicates and 1 sow per replicate.The experimental period is from 85 days of pregnancy to 10 days after weaning,totaling 65 days.The results showed that:1)Compared with groupⅠ,groupⅡandⅢsows had significantly shorter birth process and estrus interval after weaning(P<0.05),while the constipation rate and average number of white fetuses in the litter were significantly reduced(P<0.05).food intake and estrus rate within 10 days after weaning were significantly increased(P<0.05).2)The litter weight,average individual weight,25 day weaning weight,and average daily gain of GroupⅡand GroupⅢwere all increased compared to Group I,but the difference was not significant(P>0.05);The diarrhea rate of piglets in GroupⅡand GroupⅢwas significantly lower than that in Group I(P<0.05).3)Serum antioxidant indicators:The serum levels of CAT,SOD,and GSH-Px in groupⅢpiglets were significantly higher than those in group I and groupⅡ(P<0.05);Compared with group I,the serum levels of CAT,SOD,and T-AOC in groupⅡandⅢsows were significantly increased(P<0.05),while the serum MDA levels were reduced,but there was no significant difference(P>0.05).4)The number of Clostridium perfringens in GroupⅡand GroupⅢwas significantly lower than that in Group I(P<0.05);Although the number of bifidobacteria and lactobacilli in groupsⅡandⅢincreased,the difference was not significant(P>0.05),and the number of Salmonella and Escherichia coli decreased with no significant difference(P>0.05).The results showed that adding fermented dioscorea opposita skin to the diet of so
