摘    要:用不含胆碱的饲料饲养草鱼鱼种,草鱼鱼种生长减慢,饲料效率降低,肝脏脂肪浸润,血浆总脂,甘油三脂,胆固醇和磷脂含量降低,随着饲料中胆碱含量的添加,草鱼生长和饲料效率改善,肝脏脂肪含量降低,血浆总脂、甘油三脂、胆固醇,磷脂含量回升。当饲料中胆碱添加量达到0.3%以上时,草鱼生长率最高,肝脏脂肪含量,血浆总脂、甘油三脂,胆固醇,磷脂与摄食天然饲料(浮萍)的草鱼基本相同。在本研究条件下,建议草鱼鱼种饲料中

Abstract:The fingerling grass carp fed a diet without choline supplement had a poorer growth, lower feed efficiency, fatty liver and a decreasing of plasma total lipid (PTL), triacylglycerol (PTG),cholesterol (PTC) and phospholipid (PPL). With increasing dietary choline, the fish weight gain and feed efficiency were improved, liver lipid fell, and plasma lipids (PTL, PTG, PTC, PPL) rose. When the diets containing more than 0. 3% choline, the carp would reach it's optimum growth, and in this case, all the physiological indexes (liver lipid content, PTL, PTG, PTC and PPL) were almost the same as that in the carp fed natural diet (duckweed). Thus, the authors suggest that the optimal level of choline in diet for the fingerling grass carp might be 0. 3%.
Keywords:grass carp  Ctenopharyngodon idellus  fingerling  choline  feed
