| 摘 要： | 选用５００只１日龄ＡＡ肉鸡仔鸡，随机分为１个对照组和４个处理组，每组设２个重复，通过降低饲料中有效磷的水平，添加不同比例植酸酶的方法进行饲喂试验。研究结果表明，植酸酶对肉鸡生长和饲料中磷利用率有明显促进作用，肉鸡日增重增加２．０１％～５．６７％，料肉比减少１．３８％～２．３１％，血清磷含量提高了１．６０～２．４６倍，植酸磷的利用率提高１１．４５％～３１．３６％，粪磷的排泄率减少了１．５８％～８．３２％，均优于对照组。

| Abstract: | The contrast trial was made with 500 a day-old AA broiler chickens randomly divided into one
control group and four trial groups. In each group there were two replicates. Reducing the level
of effective phosphorus in diets and supplementing different levels of phytase,we did the trial to
checken the feeding effects of phytase.The result of the trial showed that supplemental phytase
accelerated broilers grouth performance increased by 2.01%5.67%,feed conversion decreased
by 1.38%2.31%,serum phosphorus was 1.602.64 times higher,the utilization of phytate
phosphorus increased by 11.45%31.36%,the level of phosphorus in excrement decreased by 1.
58%8.32%,all were superior to the control group. |
