摘要 为了研究日粮中添加米曲霉发酵玉米秸秆粉代替等量玉米对鸡肠道微生物和消化酶的影响,选择25只6周龄AA肉鸡,随机分成5组,正处理组设添加4%、8%和12%3个水平的发酵秸秆代替基础日粮中等量玉米,用基础日粮(对照组)和8%未发酵秸秆(负处理组)替代基础日粮中等量玉米作对比。结果显示:与负处理组和对照组相比,日粮中添加8%发酵玉米秸秆粉使回肠和盲肠中的乳酸菌和米曲霉的数量显著增加(P<0.05),大肠杆菌数显著降低(P<0.05);纤维素酶、蛋白酶和淀粉酶活力显著提高(P<0.05)。 A total of twenty five AA broilers at six week of age were randomly assigned to five groups to study the effects of corn straw fermented with Aspergillus oryzae instead of corn on digestive enzyme activities and gut microbes of broilers.For control groups,broilers were basal diet or added 8% unfermented corn straw instead of corn.The other three experimental groups were added 4%,8% and 12% fermented corn straw instead of corn,respectively.The results showed compared with the control groups,three diets containing fermented corn straw increased both lactic acid bacteria and Aspergillius oryzae amount ( P〈0.05) and decreased E.coli amount in ileum and cecum of broilers ( P〈0.05).The intestinal digestive enzyme activities such as cellulase,protease and amylase were significantly increased ( P〈0.05) by the fermented corn straw.The optimal level of fermented corn straw instead of corn was 8%.
