亚麻油替代鱼油对鲤鱼生长性能、肝胰脏脂质代谢及抗氧化能力的影响
Effects of Replacement of Fish Oil by Linseed Oil on Growth Performance, Lipid Metabolism and Antioxidant Ability in Hepatopancreas of Common Carp (Cyprinus carpio)
摘要
Abstract
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.关键词
