胫骨密度和骨矿物含量反映了其骨质量状况，是对磷水平较为敏感的指标，若钙磷不足，会导致蛋禽的骨质疏松症。
Abstract : This experiment was conducted to investigate the effects of dietary non-phytin phosphorus (NPP) level on laying performance, egg quality and tibia indices of ducks during the laying peak.
主要观察指标：右胫骨上端钻孔减压术前后骨内压测量值和骨髓血液流变学数值。
MAIN OUTCOME MEASURES: Value of intraosseous pressure and medullary blood rheology before and after drilling decompression in the proximal right tibia.
本试验条件下，日增重和胫骨磷含量这两个指标较能反映肉鸭磷需要量，无机磷在饲粮中的适宜水平为0.38%。
In this research, BWG and tibia phosphorus concentration reflected the phosphorus requirement of ducks (0-14 day) and the optimal adding level of inorganic phosphorus was 0.38%.
