摘　　要：试验旨在研究饲粮钙磷水平对矮脚黄肉鸡生长性能及胫骨灰分含量影响,得到矮脚黄肉鸡适宜的饲粮钙磷水平。综合肉鸡的生长性能及胫骨灰分含量的数据来看,矮脚黄肉鸡小鸡阶段饲粮的钙水平为0.90%,非植酸磷水平为0.40%,中鸡阶段饲粮钙水平为0.85%,非植酸磷水平为0.36%,大鸡阶段饲粮钙水平为0.80%,非植酸磷水平为0.33%可满足肉鸡生长及骨骼发育需要,在此基础上钙磷水平下调,肉鸡胫骨灰分含量显著降低(P<0.01)。The experiment was conducted to study the effects of different dietary calcium and phosphorus levels on the growth performance and tibia ash content of dwarf yellow broilers, and the appropriate dietary calcium and phosphorus levels in dietary for yellow broilers were obtained. The data of growth performance and tibia ash content of broilers showed that the dietary calcium and non-phyrate phosphorus levels for chick were 0.90% and 0.40%, for growing broiler were 0.85% and 0.36%, for finishing broiler were 0.80% and 0.33%, respectively. And these levels could meet the demands of growth and bone development for yellow broilers. The tibia ash content of yellow broilers could decrease significantly （P〈0.01）, if the dietary calcium and phosphorus levels down-regulated on this basis.
