摘　　要：将 14 0羽育雏至 10日龄红波罗公雏随机分成 5组 ,即低磷组 ,添加无机磷组 ,每公斤日粮添加 12 5单位(U)、 2 5 0 U和 5 0 0 U植酸酶试验组 ,进行饲养试验、代谢试验、血清及胫骨灰中 Ca、 P、Zn含量测定。结果表明 ,添加 5 0 0 U· kg- 1植酸酶组与低磷组和无机磷组相比 ,10～ 4 0日龄净增重和饲料转化率分别提高 9.4 2 % (P<0 .0 5 )、 18.78%和 9.0 8% (P<0 .0 5 )、 14 .6 8% ;血清中 Ca、 P、 Zn含量分别比低磷组提高 0 .19%、 33.8%(P<0 .0 5 )、 11.4 3% (P<0 .0 5 ) ,比无机磷组分别提高 7.92 % (P<0 .0 5 )、 14 .2 5 %、 0 % ;胫骨灰中 Ca、P、Zn含量分别比低磷组提高 7.5 7% (P<0 .0 5 )、 3.72 % (P<0 .0 5 )、 2 .5 6 % ,比无机磷组分别提高 0 .5 2 %、 0 .6 2 %、8.11% ;饲料中 P的表观利用率分别提高 36 .95 % (P<0 .0 1)和 19.32 % (P<0 .0 1)One hundred and forty ten\|day\|old Redbro male chickens were randomly divided into five groups: GroupⅠ(low level P),Group Ⅱ(addition of inorganic P),Group Ⅲ,Ⅳ,Ⅴ were additon of P at dose of 125,250 and 500 U·kg -1 phytase respectwely,and two replicates in each group.The feeding trial, metabolic trial and Ca,P,Zn test contained in serum and rib ash showed that Group Ⅴ achieved the best result Compared with Groups Ⅰ and Ⅱ,its daily gain weight and feed conversion ratio in 10-40 days old increased by 9 42%( P <0 05), 18 78% and 9 08%( P <0 05), 14 68%, respectively Ca, P, Zn content in serum increased by 0 19%, 33 8%( P <0 05)and 11 43% ( P <0 05) than those of Group Ⅰ,and 7 92% ( P <0 05), 14 25%( P <0 05),0% than those of Group Ⅱ. Ca, P and Zn content in rib ash increased by 7 57%( P <0 05), 3 72%( P <0 05), 2 56%( P >0 05)than those of Group Ⅰ,and 0 52%( P >0 05), 0 62%, 8 11% than those of Group Ⅱ,the apparent utilization ratio of P in feed increased by 36 95% ( P <0 01), 19 32% ( P <0 01).
