Effect of Ginkgo biloba extract on serum biochemical index and liver function of Cichlasoma managuense
The study was to investigate the effect of various levels of Ginkgo biloba extract(EGB)on the serum antioxidant function,liver function,lipid metabolism,and serum glucose of Cichlasoma managuense.A total of 240 Cichlasoma managuense with an average weight of(60.30±0.25)g were selected and randomly divided into four groups,with three replicates in each group and 20 fish in each replicate.The G0 group(control group),G1 group,G2 group,and G3 group were supplemented with 0,50,100,and 200 mg/kg EGB of in the basic feed.The experimental period lasted for 28 days.The results showed that the activity of T-SOD,GSH-Px and the content of HDL-C in the serum of test fish in the G2 group were higher than those of the control group at 21 days(P<0.05).Compared with the control group,the content of GLU,LDL-C,CHO,TG and MDA and the activity of CAT,ALT and AST in the G2 group were reduced(P<0.05).The study indicates that the addition of EGB to the feed can regulate blood lipid metabolism and improve the antioxidant capacity of Cichlasoma managuense,which can be used to prevent and treat hyperlipidemia.The optimal EGB dosage is 100 mg/kg for 14~21 days.
