| 摘 要： | 在室内水族缸中,采用五种不同蛋白水平、蛋白质量的饲料对草鱼氮、磷排泄影响进行测定,结果表明:对不同蛋白水平组.当粗蛋白水平为30%时,氮、磷排泄率最低(34.05%),粗蛋白高于或低于此值时,氮、磷排泄率呈增加趋势;对不同蛋白质量组:鱼粉组氮排泄率最高,而磷排泄率在各组无显著差异。

| Abstract: | We fed indoor aquatic animals with fodders containing different protein levels and qualities and mensurated their effects on the excretions of nitrogen and phosphor in grass carps.The results have shown that for fodders containing different protein levels, the excretion of nitrogen and phosphor was the lowest (34.05%) when the crude protein reached 30%,and the excretion increased gradually otherwise;and for fodders containing different protein qualities,the excretion of nitrogen was the highest,fed with fish meal. while that of phosphor had no notable change at all. |
