在18种常用肉鸭饲料原料中添加750 U/kg的植酸酶,通过鸭的强饲代谢试验来探究植酸酶对钙、磷及干物质、粗蛋白、粗脂肪、能量等真利用率的改善程度。结果表明:与加酶前比较,加酶后供试原料的总磷真利用率的提高幅度为0.92%~17.29%,其中,对次粉2、麦麸、米糠、玉米总磷的提高幅度差异达到显著或极显著水平,分别为11.79%(P

The study was conducted via metabolic experiment of forced feed on Linwu ducks to determine the effects of phytase （750 U/kg） supplemented to 18 kinds of feedstuffs on the utilization of calcium, phosphorus, and other nutrients. Results showed that the true utilization rate of phosphorus by the supplementation of phytase to all feedstuffs could be improved by range from 0.92% to17.29%, and among of which, to wheat middling 2, wheat bran, rice bran, and corn powder were improved 11.79% （P〈0.05）, 8.46% （P〈0.05）; 17.29% （P〈0.05） and 16....
