实验选用初始作重约1．4g的草鱼，在60天的饲养期中分别投喂1种不含脂肪的饲料和8种含3％不同脂质的饲料，观察了饲料中添加油酸（18：1n-9）、亚油酸（18：2n－6）、亚麻酸（18：3n－3）和n－3系列高度不饱和脂肪酸（n－3HUFA；20：5n－3＋22：6n－3）对草鱼肝胰脏、肌肉、头部和去肝胰脏内脏脂质含量和脂肪酸构成的影响。实验结果表明，与摄食单纯含油酸饲料的草鱼相比，含1％18：2n－6和1％18：3n－3或1％18：2n－6和0．5％n－3HUFA饲料组草鱼的肝胰脏脂质含量显著降低，但内脏脂质含量升高。向饲料中添加18：2n－6、18：3n－3和n－3HUFA能明显影响草鱼肝胰脏、肌肉和头部脂质多不饱和脂肪酸的相对含量；组织中n－6系列和n－3系列高度不饱和脂肪酸含量分别与饲料中添加18：2n－6和18：3n－3有相关关系，表明草鱼具有生物转化18：2n－6和18：3n－3为高度不饱和脂肪酸的能力。
Grass carp weighing about 1.4 g was initially selected for the experiments. One fat-free diet and eight different diets containing 3% different lipid were fed during the 60-day feeding period. The effect of adding oleic acid (18: (18: 2n-6), linolenic acid (18: 3n-3) and n-3 series highly unsaturated fatty acids Effects of fatty acid composition and visceral lipid content in liver, pancreas, muscle, head and liver and pancreas of grass carp. The experimental results showed that grass carp containing 1% 18: 2n-6 and 1% 18: 3n-3 or 1% 18: 2n-6 and 0.5% The hepatopancreas lipid content decreased significantly, but visceral lipid content increased. Addition of 18: 2n-6, 18: 3n-3 and n-3HUFA to feed significantly affected the relative contents of liver-pancreas, muscle and head lipid polyunsaturated fatty acids in grass carp. The n-6 series and n- The results showed that grass carp had the ability of biotransformation of 18: 2n-6 and 18: 3n-3 to highly unsaturated fatty acids .
