| 摘 要： | 本研究结果表明:草鱼对饲料钙磷的消化吸收受水中钙磷浓度的影响。草鱼能直接从水中吸收利用钙磷。鱼体存积的大部分来自于水,而磷则大部分从饲料中获得,草鱼钙磷的利用按Ca/P≈1.6的比值进行。

| Abstract: | The results of the reseach showed that digestibility and absorption of dietary calcium and phosphorus by grass carp are influenced by the concentration of Ca and P in the water. Grass carp can absorb directly Ca and P from the water. Ca deposited in the body of grass carp mainly come from the water, and P mostly abtains from diet, Ca and P is utilized by grass carp on the ratio of Ca/P being 1.6. |
