以黄颡鱼幼鱼为材料，进行为期8周的饲养试验，研究饲料中有效磷（P）对黄颡鱼生长性能、体成分和肝脏抗氧化性能的影响。六个颗粒饲料配制含有分级有效磷水平分别为0.33，0.56，0.81，1.15，1.31，和1.57%的干物质。每箱60尾（3.09 ± 0.03 g）的三重鱼用6种试验饲料中的一种饲喂8周。当饲料有效磷水平为0.81%时，幼鱼的特定生长率、摄食率和蛋白质效率显著提高，磷利用率随磷水平的提高而显著降低。随着磷水平的增加，体脂肪含量显著降低，而体灰分和粪便磷含量显著增加。二次回归分析表明，脊椎骨磷含量最大，在1.21%的饲料有效磷。鱼喂1.57%的饲料有效磷有最高的肝脏超氧化物歧化酶和过氧化氢酶的活性和丙二醛含量。降低饲粮有效磷水平可提高磷的利用率，降低脊椎骨磷含量，提高体脂肪含量。高磷饲料（1.57%）对黄颡鱼幼鱼造成了氧化损伤，且这种损伤不能通过黄颡鱼自身的抗氧化防御系统来消除。
An 8-week feeding trial was carried out with juvenile yellow catfish to study the effects of dietary available phosphorus (P) on growth performance, body composition, and hepatic antioxidant property. Six pellet diets were formulated to contain graded available P levels at 0.33, 0.56, 0.81, 1.15, 1.31, and 1.57% of dry matter, respectively. Triplicate tanks with each tank containing 60 juveniles (3.09 ± 0.03 g) were fed one of the six experimental diets for 8 weeks. Specific growth rate, feeding rate, and protein efficiency ratio were significantly higher at 0.81% dietary available P. Efficiency of P utilization distinctly decreased with increasing P level. Body lipid content significantly decreased while body ash and feces P content significantly increased with increasing P level. Quadratic regression analysis indicated that vertebrae P content was maximized at 1.21% dietary available P. Fish fed 1.57% dietary available P had highest activity of hepatic superoxide dismutase and catalase and malonaldehyde content. In conclusion, decreasing dietary available P increased P utilization efficiency and body lipid content while decreased vertebrae P content. Juvenile yellow catfish were subjected to oxidative damage under the condition of high dietary P content (1.57%), and the damage could not be eradicated by their own antioxidant defense system.
