摘　　要：通过饲养试验、代谢试验、骨灰分含量测定及血清磷浓度测定等方法 ,测得 MCP、DCP、TCP、SP四种不同化学形式的无机磷源在肉雏鸡体内的生物学效价以体增重为指标时分别为 10 0、98、10 0、89;以磷存留率为指标时分别为 10 0、92、98、78;以骨灰分含量 (胫骨灰分和趾骨灰分含量的平均值 )为指标时分别为 10 0、93、92、81;以血清磷浓度为指标时分别为 10 0、96、98、90 .研究结果还表明 ,以上述 4项指标平均值作为综合依据的四种不同化学形式无机磷源的生物学效价分别为 10 0、95、97、85 ,说明以MCP作为肉雏鸡日粮的无机磷源利用效果最好 ,DCP、TCP也是雏鸡较好的磷源 ,而A grouped feeding trial, metabolism trial, and mensuration of bone and serum were made to determine biological value of inorganic phosphorus sources in various chemical forms for broiler chickens. It showed that biological value of MCP, DCP, TCP and SP were scored in hundred mark system as follows, respectively: 100,98,100 and 89 when body weight gain was employed as response criterion;100,92,98 and 78 when ratio of phosphorus retention was employed; 100,93,92 and 81 when bone ash content (the average of tibia ash and toe ash) was employed; 100,96,98 and 90 when serum phosphorus level was employed and 100,95,97 and 85 when scores of all above four criteria were averaged. It was concluded that MCP was the best inorganic phosphorus source for broiler chickens, DCP and TCP were also ideal inorganic phosphorus sources with high efficiency and SP was relatively inferior.
