| 摘 要： | 在高蛋白半纯化饲料中分别添加0，30，50，70，90g/kg的未加抗氧化剂的新鲜鱼油，投喂58g左右2龄鲤（Cyprinus carpio)鱼种46d , 结果表明，添加新鲜鱼油量为30g/kg时，鲤生产性能最佳，鲤肝体比（HSI），肝胰脏脂肪含量，肌肉营养不良症和肌肉渗出性损失随着钎油添加量的增加而持续上升，而肌肉和肾脏氧化稳定性则随着鱼油添加量的增中而持续下降，当添加鱼油量升至30，70，70，50，70，70g/kg时，上述6项指标与对照组差异显著（P＜0．05），综合各项指标，未添加抗氧化剂的新鲜鱼油在高蛋白质鲤饲料中适宜用量以不超过30g/kg为宜。

| Abstract: | Juvenile carp of 58 g were fed a high protein semi-purified feed supplemented with 0, 30, 50, 70, 90 g/kg fresh fish oil with no supplemention of antioxidant (Peroxide value,POV,0.64 mmol/kg ) for 46 days. The results showed that the carp had the best performance at 30 g/kg supplementation of fish oil. With the increment of fish oil supplementation, hepatopancreas somatic indices (HSI), fat content in hepatopancreas, muscular dystrophy and muscular exudative losses were increased, while oxidative stabilities of muscle and kidney were reduced. There were significant differences in fat content in hepatopancreas, muscular dystrophy, and oxidative stabilities of muscle and kidney between the control group (no fish oil supplementation) and the 70 g/kg or higher fish oil supplemented groups\% (P<\{0.05\})\%. HSI of the control group was significantly different with that at 30 g/kg or higher fish oil supplemented groups \%(P<0.05)\%. Compared with the control group, the muscular exudative losses was significantly different at 50 g/kg or higher fish oil supplemented groups\%(P<\{0.05\})\%. In conclusion, fresh fish oil with no supplemention of antioxidant should be supplemented in carp feed with high protein at no more than 30 g/kg. |
