本文报道了饲料中不同脂肪含量对施氏鲟生长及其肝脏脂质组成的影响结果 .试验饲料是以酪蛋白质、鱼粉、糊精和纤维素等为主要原料配制而成的等氮和等能量的半精制饲料 ,以等量混合的海水鱼油、豆油作为脂肪源 .试验周期为 2 5d .结果表明 :施氏鲟饲料中脂肪适宜含量为 5.6 %～ 1 1 .4% ,最适含量为 7.5%左右 ;肝脏脂质含量和中性脂质含量随着饲料脂肪添加量的增加而升高 ,但在饲料脂肪适宜含量范围内各组间却无显著差异 .

In this paper, the effects of different fat content in feed on the growth of sturgeon Acipenser schrenckii and its liver lipid composition were reported.The experimental diets were made of casein, fish meal, dextrin and cellulose as the main raw materials, Of semi-refined feed, the same amount of mixed seawater fish oil, soybean oil as a fat source.The test period was 25d.The results showed that the suitable content of fat in the feed of Amur sturgeon was 5.6% ~ 11.4%, the optimum content was 7.5 %; Liver lipid content and neutral lipid content increased with the increase of feed fat, but there was no significant difference among the groups in the suitable feed fat content.
