摘    要:将试验草鱼随机分配在 12个水族箱中 ,每箱放鱼 30尾 ,分别以玉米淀粉、小麦淀粉、水稻淀粉为糖源配制 3种试验饲料 ,饲养初始体重为 (8.49± 0 .0 4)g的草鱼 80d ,观察不同种类淀粉饲料对草鱼生长、肠系膜脂肪沉积和鱼体组成的影响。每种饲料设 3个平行组 ,日投喂率按鱼体重的 3%计算。试验结果显示 :尽管草鱼对糖的表观消化率以小麦淀粉组最高 ,但摄食小麦淀粉饲料的草鱼与摄食玉米淀粉和水稻淀粉饲料的草鱼在生长上并无显著性差异。然而小麦淀粉组和玉米淀粉组的内脏比、肝胰脏脂肪含量、血浆甘油三酯水平以及肠系膜脂肪占鱼体的百分比显著高于水稻淀粉组 (P <0 .0 5 )。鱼体营养成份组成除了水稻淀粉组全鱼脂肪含量相对低于玉米淀粉组和小麦淀粉组之外 ,其它成份没有太大的差异。

关 键 词:种类  淀粉  草鱼  生长  肠系膜脂肪沉积  鱼体组成

Abstract:Grass carps (8. 49 ±0. 04g) were randomly assigned to 12 tanks (30 fish/ tank) and fed with three experimental diets , which contained 30 % different types of starch (corn starch , wheat starch and rice starch) for 80 days. Daily feeding rate was 3 % wet weight. The results showed that there was no significant difference in growth of fish fed with wheat starch , corn starch and rice starch , even though highest carbohydrate apparent digestibility coefficients occured in wheat starch fed fish. While viserosomatic index , hepatopancreatic fat content , plasma trigliceride level and percentage mesenteric fat were significantly higher in fish fed with wheat starch than in those fed with rice starch. The differences in body composition were small except that the body fat content of fish fed with rice starch was relatively lower than those fed with corn starch or wheat starch.
Keywords:Ctenopharyngodon idellus  starch  growth  mesenteric fat  body composition
