摘要 将肉用仔鸡分为10组,第1-5组饲糖中含钙1%,含有效磷相应为0.1,0.3%.0.5%,0.7%,0.9%;第6-10组含有效磷0.5,0-28日龄,含钙量相应为0.4%,0.7%,1%,1.3%,1.6%,35-42日龄时,含下量相应为0.4%,0。7%,1.9%,1.3%,1.6%。结果表明,磷含量最低的第1组增重、胫骨灰分、胫骨总钙与总磷显著低于其余组,而料肉比、腿病发生率及死亡率比其余组 Three hundred and sixty one一day一old male parant Peterson broilers were used in this experi-ment and divided into l0 groups randomly. Calcium content in diets for groups I to 5 was l%and the phos-phorus levels were 0.1%,0.3%,0.5%,0.7%and 0.9%, respectively。 For groups 6 to l0,the dietary Pcontent was fixed at 0.5%and the Calevels were 0.4%,0.7%,1.O%,1.3%and l.6%,respectively。There was an exception for group 8 that the dietary Ca content was enhanced from l.o%to l.9%during thelast 2 weeks,Results showed that the lowest weight gain,feed conversion rate, bone ash vveight,and Ca andPcontents of tibias were found in broilers fed on lowest P diet(group l),and the rates of leg disease anddeath were much higher in this group than those in others.Of groups with dietary Ca:P ratio around l,therates of birds suffering from leg disease and mortality were highest next to group l。
