甘露聚糖-寡糖对断奶仔猪腹泻的防制

Effects of Mannanoligosaccharides on Control of Diarrhea in Weanling Pigs

为了探讨新型化学益生剂甘露聚糖－寡糖（ｍａｎｎａｎｏｌｉｇｏｓａｃｃｈａｒｉｄｅｓ，ＭＯＳ）对家畜肠道致病菌的去粘附作用及免疫调节作用的机制，进行了断奶仔猪的饲养试验，试验选用了三元杂交断奶仔猪［（长白Ｘ大约）］杜３２头，随机对半分成对照组和处理组；处理组在常规日粮中拌入Ｂｉｏ－ＭＯＳ（２ｇ／ｋｇ饲料），试验期３０天。结果表明，断乳仔猪添加 Ｂｉｏ－ＭＯＳ，可明显提高仔猪的日增重（ｐ＜ ０． １０５），降低腹泻发生率（ｐ＜ ０．０５），提高机体的细胞免疫和体液免疫水平，增强非特异性免疫力。

For the sake of prebing into the mechanisms of detachment role of new probiotics Bio-MOS in preventing enteric pathogen colo- nization, a feeding trial was conducted in weanling pigs. In the trial 32 three-way-crossbred weanling pigs were used and divided into two groups- control and treatment. Bio-MOS was added to the conventional diet at a dose of 2 gram per ton feed, and the trial lasted for 30 days.The results showed that the addition of Bio-MOS could markedly improve daily gains(p < 0.05), lower t...
