| 摘 要： | 选用400只7日龄艾维茵雏鸡,研究玉米-豆粕型日粮中添加0,300,600,900IU/kg重组植酸酶和标准水平磷酸氢钙对肉鸡生长性能和磷利用的效果.结果表明,肉鸡体增重和胫骨磷沉积随植酸酶添加剂量而提高,但添加植酸酶不能完全取代无机磷.添加植酸酶可减少肉鸡粪便氮磷排泄量,减轻环境污染.

| Abstract: | Four hundred seven-day old Avian broiler chickens were used to evaluate the effect of 0,300,600 and 900 IU/kg recombinant phytase on the performance and phosphorus utilization in comparison with dicalcium phosphate supplemented diet.The result indicated that body weight gain and phosphorus deposition in tibia were improved by supplementation of the phytase with a dosage dependent relationship,but the phytase could not replace phosphorus supplementation completely.Phytase supplementation reduced excreta nitrogen and phosphorus output and could relieve the pollution. |
