摘　　要：使用48头体重为60 kg左右的杜长嘉三元杂交猪作为试验动物,根据体重相近、公母各半的原则将其分为对照组、试验组1和试验组2,研究日粮中不同含量的纤维对于肥育猪消化道发育和消化酶活性的影响。以甜菜渣和苜蓿草粉作为试验组日粮的主要纤维源,3个组的粗纤维含量分别为3％、6％和8％。结果表明,日粮纤维具有促进消化道发育的作用;日粮纤维对胰脏和十二指肠中各种蛋白酶的活性均产生显著性的影响(P<0.05)。Forty-eight pigs (Duroc×Landrace×Jia) were divided into control. Treatment 1 and Treatment 2 groups by weight and sex. Sugar beet pulp and alfalfa hay meal were selected as main fiber sources in tested diets. The results showed that dietary fiber had a trophic effect on the digestive system in finishing pigs t dietary fiber had the significant effects on activity of proteolytic enzyme in pancreas and duodenum (P<0. 05).
