摘要
试验旨在研究基础日粮添加复合酶制剂对肉仔鸡小肠消化酶活性和代谢的影响。试验分为对照组和添加0.1%复合酶组,结果表明:酶制剂对玉米-豆粕型饲料的能量利用效率有所提高,但差异不显著;试验组净蛋白利用率较对照组提高8.56%(P<0.05);试验组20日龄肉鸡淀粉酶活性、蛋白酶活性和35日龄蛋白酶活性显著高于对照组(P<0.05);35日龄肉鸡血糖浓度、20日龄和35日龄肉鸡血清尿素氮试验组均显著高于对照组(P<0.05)。
The effects of enzyme preparations supplemented in basal diet on the digestive enzyme activity of small intestine and metabolism in broiler were studied, The results showed that enzyme preparations could increase the energy utilization efficiency of corn-soybean meal feed but have no significant effects. Comparison with control group, net protein utilization rate raised 8.56%（P〈0.05）in treatment group,activity of amylase and protease of 20-day-old chicken and protease of 35-day-old chicken were significantly higher than that of control group as well as enhanced blood glucose concentration of 35-day-old broiler chickens and serum urea nitrogen（P〈0.05）of 20-day-old and 35-day-old broiler.
