摘　　要：试验选用270羽1日龄艾维茵健康肉仔鸡,随机分成3组,研究了玉米-豆粕型日粮条件下添加不同水平的木聚糖酶对肉鸡生产性能和内源酶活性的影响。结果表明,添加25g/t和50g/t的木聚糖酶可提高肉鸡的日增重,降低料重比;提高胃蛋白酶、胰蛋白酶、胰淀粉酶和胰脂肪酶酶活力,同时亦显著提高了肉鸡的生产效益。Different xylanase levels （25 g/t, 50 g/t） were supplemented in the diet to investigate the effects of xylanase on growth performance and endogenous enzyme activities of broilers fed corn-soybean meal diets. The results showed that ADG and FCR increased with xylanase supplementation. Results also demonstrated that, compared with the control, endogenous enzyme activities in pancreas and crop mucosa pepsin activities increased in the treatment group. The results indicated that xylanase supplementation to corn-soybean meal diets can improve the activities of endogenous enzymes and the growth performance of the broilers.
