摘要
试验选用30头断奶八眉二元仔猪,随机分为3组,即对照组、试验A组和试验B组,每组10头,对照组饲喂基础饲粮,试验A、B组在基础饲粮中分别添加0.1%和0.3%甘露寡糖。观察仔猪在不同甘露寡糖添加水平下生长性能和腹泻率的变化。结果表明,三组间日增重差异显著(P<0.05),而料重比试验A和B组与对照组相比较差异均达到显著水平(P<0.05),但两个试验组之间差异不显著(P>0.05)。试验结果表明,在断奶仔猪日粮中添加甘露寡糖可以降低腹泻率及腹泻指数。通过经济效益分析,发现试验A组和试验B组平均每头仔猪收入比对照组分别提高90.03%和90.13%。
30 weaning piglets were selected and divided randomly into three groups, i.e. control groupfed based diet; group A fed basal diet supplemented 0.1% mannan oligosaccharide（MOS）; groups Bfed basal diet supplemented 0.3% MOS. The results showed that： daily gain were significantly differentamong three groups（P〈0.05）. Rate of feed to gain of group A and B were significantly lower than thatof the control group（P〈0.05）, but there were no obvious differences between group A and B（P〈0.05）.Compared with the control group, diarrhea rates and diarrhea index of group A and B were reduced byMOS. As of the economic benefit analysis, average income of each piglet at group A and B were in-creased by 90.03% and 90.13%.
