摘　　要：以 6 0头“杜长嘉”断奶仔猪为研究对象 ,研究了大麦日粮中添加 NSP复合酶制剂对仔猪消化机能的影响 .结果显示 ,添加 NSP酶使仔猪十二指肠内容物中葡萄糖和胆汁酸含量分别提高了4 8.91% (P<0 .0 1)和 73.5 0 % (P<0 .0 1) ;空肠内容物粘度降低了 6 .31% (P<0 .0 5 ) ;空肠粘膜绒毛和微绒毛高度分别提高了 5 0 .0 0 % (P<0 .0 1)和 5 5 .91% (P<0 .0 1) ,粘膜层变薄 ,为对照组的 72 .0 0 %(P<0 .0 1) .此外 ,大肠杆菌数和仔猪腹泻率也分别降低了 6 9.80 %和 6 2 .5 9% (P<0 .0 5 )Sixty piglets (Duroc×Yorkshire×Jia) were used to study the effects of NSP enzymes (including β glucanase, xylanase and cellulase) added to barley based diets on digestive function of piglets The results showed that compared to control group , NSP enzymes increased the content of glucose and bile acid in small intestinal digesta by 48 91% ( P <0 01) and 73 50% ( P <0 01) , decreased the viscosity by 6 31% ( P <0 05); increased the height of villi and microvilli by 50 00% ( P <0 01) and 55 91% ( P <0 01), decreased the depth of mucosa layer by 72 00% ( P <0 01),the number of E coli in feces and diarrhea morbidity by 69 8% and 62 59% ( P <0 05), respectively
