【摘要】 借鉴人类营养学中的FTT试验方法,以无脂纯化饲料为对照,采用脂肪含量为12%的高脂纯化饲料,对草鱼Ctenopharyngodonidella摄食高脂饲料后血脂(甘油三酯、胆固醇、高密度脂蛋白和低密度脂蛋白)的变化进行了连续观察。以摄食前血脂相关指标水平为基础水平,每隔1 5h取样一次,连续观察9h。结果表明,草鱼摄食高脂饲料后血脂升高,出现两个吸收高峰,分别出现在摄食后1 5h和6h,同时在摄食后4h和9h达到或接近基础水平。提示草鱼摄食高脂饲料后血脂变化情况与人类等哺乳动物不同,鱼类FTT试验的相关参数尚需进一步探索。更多还原

【Abstract】 Juvenile grass carp (Ctenopharyngodon idella)(6.33±1.23) g were been fed two purified formulated diet with different fat content (Control diet: non_fat content; Experimental diet: 12% fat content) to observe the effect of high_fat content diet on the change of four blood lipid indexes (triacylglycerol, cholesterol, low density lipoprotein and high density lipoprotein) after fed. Blood examples were collected before fed (base level) and hour 15, 3, 45, 6, 75, 9 after fed respectively. The results showed the blood lipid increased after fish fed high_fat diet. At 15 h and 6 h, all blood lipid indexes reached the maximum level and at 4 h, 9 h, all the indexes reached the base level. These suggested there existed some differences of fat tolerance ability between fish and mammal.更多还原
