| 摘 要： | 选用1日龄AA肉仔鸡360只进行为期6周的饲养试验。对照组饲喂有效磷含量为0.45%(0~3周)和0.40%(4~6周)的基础日粮,不添加包衣植酸酶;处理1、处理2饲喂有效磷含量为0.35%(0~3周)和0.30%(4~6周)的日粮,并分别在日粮中添加250、500 FTU/kg的包衣植酸酶;处理3、处理4饲喂有效磷含量为0.25%(0~3周)和0.20%(4~6周)的日粮,并分别在日粮中添加250、500 FTU/kg的包衣植酸酶。结果表明:与对照组相比,处理1、处理2的饲料利用率均得到显著提高(P<0.01),且日增重也有提高的趋势(P>0.05);处理3的日增重显著低于对照和其余各处理(P<0.05),其饲料利用率没有得到显著改善(P>0.05);处理4的日增重比对照有提高的趋势(P>0.05),且饲养后期的饲料利用率得到显著提高(P<0.01)。各处理的钙、磷消化率与对照差异不显著(P>0.05)。各处理的胫骨灰分和钙含量与对照差异不显著(P>0.05);处理4的胫骨磷含量显著高于对照(P<0.05),其余各处理与对照差异不显著(P>0.05)。

| Abstract: | Three hundred and sixty 1-day-old Arbor Acre(AA) chicks were randomly allocated to 5 groups with 6 replicates of 12 chicks each replicate.The feeding trial involved 2 periods(0~3 and 4~6 week of age).The chicks in the control group were fed with basal diets containing 0.45%(0~3 week) or 0.40%(4~6 week) available phosphorus,and without supplemental coated phytase.The chicks in treatment 1 and 2 were fed with basal diets containing 0.35%(0~3 week) or 0.30%(4~6 week) available phosphorus,and with 250 FTU/kg,50... |
