本试验旨在研究酵母多糖对断奶仔猪生长性能、肠道形态、抗氧化能力和肠道免疫状态的影响.试验选取体重[(6.89±0.88) kg]相近、健康状况良好的21日龄长×大×杜杂交阉公断奶仔猪32头,随机分为4个组,每组8个重复,每个重复1头猪.对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮中添加0.1%酵母多糖(0.1%酵母多糖组)、0.2%酵母多糖(0.2%酵母多糖组) 、55 mg/kg吉他霉素和20 mg/kg硫酸黏菌素(抗生素组)的试验饲粮.预试期3 d,正试期28 d.结果表明:与对照组相比,1)饲粮中添加0.1%酵母多糖可显著增加断奶仔猪的平均日增重和平均日采食量(P＜0.05) ,显著降低盲肠内容物pH( P＜0.05) ;添加0.1%和0.2%酵母多...

This study was conducted to investigate the effects of yeast polysaccharide on growth performance, intestinal morphology, antioxidant capacity and intestinal immune status of weaned piglets. Thirty-two healthy Landrace×Yorkshire×Duroc castrated male weaned piglets at 21-day-old with similar body weight of (6.89 ± 0.88) kg were randomly divided into 4 groups with 8 replicates per group and 1 pig per replicate. Pigs in control group were fed a basal diet, and the others in experimental groups were fed the basal diets supplemented with 0.1% yea...
