摘　　要：为考察纯化饲料中不同饲料磷水平对草鱼生长性能的影响,对草鱼(初始均重为22.29 g)进行了75 d的饲养试验,结果表明:饲料磷水平显著影响草鱼的生长,当饲料中磷的添加水平为8.07 g/kg时,草鱼的生长效果最好;饲料磷水平对草鱼的体组成有一定的影响,但是规律不明显;全鱼磷含量和鳃盖骨磷含量与饲料磷水平有较强的相关性;当饲料磷水平为11.63 g/kg时,草鱼血清的GPT和GOT含量最低,饲料磷水平对血脂四项、血糖、白蛋白、球蛋白、肌酐等的影响不显著。通过试验研究认为草鱼纯化饲料中的磷的适宜添加量为8.07 g/kg。A 75 days feeding trial was conducted to investigate effects of different phosphorus levels ongrowth in grass carp（Ctenoparyngodon idellus）（average body weight were about 22.29 g）. The resultsshowed that： with the increasing of the phosphorus levels, the growth had a significant difference,8.07 g/kg phosphorus supplementation in the feed would had a best growth; body composition of grasscarp had no significant differences; As of the percentage of phosphorus in whole fish and opercular,there was a strong correlation among the content of whole fish, opercular and feed; the grass carp se-rum GPT and GOT were the lowest when dietary phosphorus level is 11.63 g/kg; there were no signifi-cant differences in serum four lipids, blood glucose, albumin, globulin, creatinine, etc. Based on the tri-als, 8.07 g/kg of phosphorus supplementation in the feed was suitable.
