摘要
研究非淀粉多糖(NSP)复合酶制剂对肉鸡养分表观利用率以及肠道组织形态结构的影响。结果表明:NSP复合酶制剂F对肉鸡玉米-豆粕型饲粮1～21d养分表观利用率无改善趋势(P>0.20);对肉鸡玉米-豆粕-DDGS型饲粮22～42d干物质、能量表观消化利用率有提高趋势(P<0.20)。NSP复合酶制剂F对采食玉米-豆粕型饲粮的肉鸡1～21d肠道组织形态结构表现正负双面效应,能显著降低采食玉米-豆粕-DDGS型饲粮的肉鸡生长后期空肠肌层厚度,改善空肠的组织形态结构。
The aim was to investigate the effects of non-starch enzymes preparation on the g nutrients apparent availability and intestine tissue morphosis of broilers. The results were as follows：The addition of enzyme preparation F in the basal diet could not improve the nutrients apparent avaibility（P〉0.20） of 1-21 d corn-soybean meal diet, could improve the dry matter, energy apparent avaibility（P〈0.20） of 22-42 d corn-soybean DDGS meal diet. The addition of enzyme preparation F in the basal diet could influence the positive and negative effect of the 21 d the broiler intestine tissue morphosis, could decrease significantly the jejunum myometrial thickness and improve the jejunum tissue morphosis.
