在一种实用饲料配方的基础上，用亚麻油分别替代0（对照组）、25％、50％、75％、100％）的鱼油配制成5种等氮等能（粗蛋白质含量为35％，总能为15 MJ/kg）的试验饲料，在室内循环养殖系统中饲喂5组鲤鱼[初重（5．81±0．23） g]8周，以研究亚麻油替代不同水平鱼油对鲤鱼生长性能、体组成、肝胰脏脂质代谢和抗氧化指标的影响。结果表明：随着亚麻油替代鱼油水平的升高，鲤鱼的特定生长率（ SGR）呈现先升高后降低的趋势，以25％组最高，显著高于75％和100％组（P＜0．05）；而饲料系数（FCR）则表现出相反的变化趋势，以25％组最低，显著低于100％组（P＜0．05）。蛋白质效率（PER）和成活率（SR）在各组间无显著差异（P＞0．05）。对照组全鱼粗蛋白质含量显著高于其他组（P＜0．05），而粗脂肪含量则显著低于除25％组外的其他各组（ P＜0．05）。亚麻油替代不同水平鱼油对全鱼干物质和粗灰分含量无显著影响（ P＞0．05）。随着亚麻油替代鱼油水平的升高，肝胰脏脂蛋白脂酶（ LPL ）活性和总抗氧化能力（ T-AOC）逐渐降低，而肝胰脏苹果酸脱氢酶（ MDH）活性则逐渐升高，但对照组与25％组均无显著差异（P＜0．05）。各组肝胰脏超氧化物歧化酶（SOD）活性无显著差异（P＞0．05）。由此可见，亚麻油替代不同水平鱼油对鲤鱼的生长性能、肝胰脏脂质代谢和抗氧化能力产生的影响不同。以亚麻油替代25％鱼油时鲤鱼的生长效果最好，而完全替代鱼油会阻碍鲤鱼的生长，并危及肝胰脏的健康。
在一種實用飼料配方的基礎上，用亞痳油分彆替代0（對照組）、25％、50％、75％、100％）的魚油配製成5種等氮等能（粗蛋白質含量為35％，總能為15 MJ/kg）的試驗飼料，在室內循環養殖繫統中飼餵5組鯉魚[初重（5．81±0．23） g]8週，以研究亞痳油替代不同水平魚油對鯉魚生長性能、體組成、肝胰髒脂質代謝和抗氧化指標的影響。結果錶明：隨著亞痳油替代魚油水平的升高，鯉魚的特定生長率（ SGR）呈現先升高後降低的趨勢，以25％組最高，顯著高于75％和100％組（P＜0．05）；而飼料繫數（FCR）則錶現齣相反的變化趨勢，以25％組最低，顯著低于100％組（P＜0．05）。蛋白質效率（PER）和成活率（SR）在各組間無顯著差異（P＞0．05）。對照組全魚粗蛋白質含量顯著高于其他組（P＜0．05），而粗脂肪含量則顯著低于除25％組外的其他各組（ P＜0．05）。亞痳油替代不同水平魚油對全魚榦物質和粗灰分含量無顯著影響（ P＞0．05）。隨著亞痳油替代魚油水平的升高，肝胰髒脂蛋白脂酶（ LPL ）活性和總抗氧化能力（ T-AOC）逐漸降低，而肝胰髒蘋果痠脫氫酶（ MDH）活性則逐漸升高，但對照組與25％組均無顯著差異（P＜0．05）。各組肝胰髒超氧化物歧化酶（SOD）活性無顯著差異（P＞0．05）。由此可見，亞痳油替代不同水平魚油對鯉魚的生長性能、肝胰髒脂質代謝和抗氧化能力產生的影響不同。以亞痳油替代25％魚油時鯉魚的生長效果最好，而完全替代魚油會阻礙鯉魚的生長，併危及肝胰髒的健康。

In order to study the effects of replacement of different levels of fish oil by linsee d oil on growth performance, body composition and indices of lipid metabolism and antioxidant in hepatopancreas of common carp, five isonitrogenous and isoenergetic experimental diets ( crude protein content was 35%, and gross ener-gy was 15 MJ/kg) were formulated by replacing 0 ( control group) , 25%, 50%, 75%and 100% fish meal with linseed oil on bsa is of a practical diet, respectively.Common carp with the initial body weight of (5.81 ±0.03) g in five groups were fed five experimental diets for 8 weeks in the room circulation farming system.The results showed as follows: with the increase of linseed oil to replace fish oil level, the specific growth rate ( SGR) of carp showed a trend of first increase and then decrease, while the feed conversion ratio ( FCR) was just the opposite.The highest SGR was found in 25%group, and significantly higher than that in 75% and 100% groups (P<0.05); the lowest FCR was found in 25% group, and significantly lower than that in 100% group (P<0.05).No significant differences were found among all groups in protein efficiency ratio ( PER) and survival rate ( SR) ( P>0 .05 ) .The whole fish crude protein content in control group was significantly higher than that in other groups ( P<0 .05 ) , while the crude fat content was significantly lower than that in other groups except 25% group ( P <0.05 ) .No significant differences were found among all groups in whole fish ash and moisture contents ( P>0 .05 ) .With the increase of linseed oil to replace fish oil level, the hepatopancreas lipoprotein lipase ( LPL ) activity and total anti-oxidant capability ( T-AOC ) were gradually reduced and the hepatopancreas malate dehydrogenase ( MDH) activity was gradually increased, but no significant differences were found in those indices between control group and 25%group (P>0.05).Re-placement of different levels of fish oil by linseed oil had no significant effect on hepatopancreas superoxide dis-mutase (SOD) activity (P>0.05).Thus, replacement of different levels of fish oil by linseed oil have dif-ferent effects on growth performance, lipid metabolism and antioxidant ability in hepatopancreas of common carp.Replacement of 25%fish oil by linseed oil, the growth of common carp shows the best effect;total re-placement of fish oil by linseed oil can hinder the growth of common carp, and endanger the health of hepato-pancreas.
