中文摘要：该文旨在探究紫檀芪对夏季高温条件下母猪繁殖性能、仔猪生长性能及其粪便微生物的影响.试验选取30头背膘相近的经产妊娠母猪(长白×大白,3胎),随机分为3组,对照组饲喂基础饲粮,P200组在基础饲粮中添加200 mg/kg紫檀芪,P400组在基础饲粮中添加400 mg/kg紫檀芪.试验期由妊娠第75天至哺乳第21天,环境温度为27℃-30℃.结果表明:与对照组相比,添加紫檀芪对母猪总产仔数、产活仔数、平均日采食量和仔猪平均日增重无显著影响(P>0.05);与对照组相比,P200组和P400组哺乳母猪粪便微生物Simpson指数显著升高(P<0.05);与P200组相比,P400组哺乳母猪粪便微生物Bacilli、Lactobacillales的相对丰度水平显著增加(P<0.05);与对照组和P200组相比,P400组哺乳母猪粪便微生物Streptococcaceae、Streptococcus的相对丰度水平显著增加(P<0.05);与对照组相比,P400组仔猪粪便微生物Firmicutes、Clostridia、Clostridiales 和Ruminococcaceae的相对丰度有增加的趋势(0.05≤P<0.10),Bacteroidetes、Bacteroidia、Bacteroidales的相对丰度有降低的趋势(0.05≤P<0.10).综上所述,饲料添加200和400mg/kg紫檀芪可以改善夏季高温条件下母猪粪便微生物多样性和母仔猪粪便微生物群落结构,但对母猪繁殖性能和仔猪生长性能影响并不显著.

外文标题：Effects of Pterostilbene on Reproductive Performance of Sows,Growth Performance and Fecal Microbiota of Piglets under High Temperature Condition in Summer

外文摘要：The aim of this paper was to investigate the effects of pterostilbene on reproductive performance of sows,growth performance of piglets and their faecal microorganisms under high temperature in summer.Thirty gestating sows(Yorkshire×Landrace,3 fetal periods)with similar backfat were randomly divided into three groups:the control group was fed with basal diet,the P200 group was supplemented with 200 mg/kg of pterostilbene in the basal diet,and the P400 group was supplemented with 400 mg/kg of pterostilbene in the basal diet.The experimental period was from the 75th day of gestation to the 21st day of lactation,and the ambient temperature was 27～30℃.The results showed that the addition of pterostilbene had no significant effect on the total number of litters,the number of live births,the average daily feed intake of sows and the average daily weight gain of piglets compared with the control group(P>0.05);the Simpson index of fecal microorganisms of lactating sows in the P200 and P400 groups was significantly higher compared with the control group(P<0.05);the relative abundance levels of fecal microorganisms of lactating sows in the P400 group compared with the P200 group,Bacilli and Lactobacillales had significantly higher relative abundance levels(P<0.05);the relative abundance levels of lactating sow faecal microorganisms Streptococcaceae and Streptococcus were significantly higher in the P400 group compared to the control and P200 groups(P<0.05);and compared to the control group,the relative abundance of piglet faecal microorganisms Firmicutes,Clostridia,Clostridiales and Ruminococcaceae in the P400 group tended to increase(0.05≤P<0.10),and the relative abundance of Bacteroidetes,Bacteroidia,Bacteroidales tended to decrease(0.05≤P<0.10).In summary,the addition of 200 and 400 mg/kg pterostilbene can improve the diversity of fecal microorganisms in sows and the structure of fecal microbial communities in both sows and piglets under high temperature conditions in summer,but has no significant effects on reproductive performance of sows and growth performance of piglets.
