摘要
研究不同水平纳米蒙脱石对断奶仔猪生产性能的影响,结果表明:添加纳米蒙脱石能降低断奶仔猪的腹泻频率和腹泻指数,Ⅰ、Ⅱ、Ⅲ组的腹泻频率比对照组分别降低了80.2%、215.1%和372.7%;腹泻指数比对照组分别降低了69.5%、218.3%和392.5%。试验前期,Ⅲ组的平均日采食量比对照组提高12.4%(P<0.05),说明在日粮中添加纳米蒙脱石可减少断奶仔猪腹泻情况的发生,且表现为剂量依赖性,高水平添加还可以提高断奶仔猪平均日采食量。
The effects of different dosages of nano-montmorillonite （MMT） on the production performance of weanling piglets were studied. The results showed that the addition of nano-MMT to diets could decrease diarrhea incidence and diarrhea index. Compared with the control group, the diarrhea incidence of Group Ⅰ, Ⅱ and Ⅲ were reduced by 80.2%, 215.1% and 372.7% respectively and the diarrhea index of Group Ⅰ, Ⅱ and Ⅲ were reduced by 69.5% ,218.3% and 392.5% respectively. During the first experimental period, the average daily feed intake （ADFI） of Group Ⅲ was significantly more than that of the control group （ P 〈 0.05） , increased by 12.4%. These results indicated that supplementation of nano-MMT to diets for weanling piglets could reduce diarrhea incidence. The more the nano-MMT, the better the effects. Moreover, addition of high level of nano-MMT could increase ADFI.
