Abstract
This study was conducted to investigate the effects of different levels of Eucommia ulmoides Oliv.extract on the antioxidant properties of Carassius auratus,and to determine the optimal supplemental level of Eucommia ul-moides Oliv.extract in Carassius auratus.600 healthy Carassius auratus with a body weight of about 50g were se-lected and divided into 4 treatments with 5 replicates per treatment and 30 Carassius auratus per replicate according to the single-factor experimental design.The control group was fed basic diet,and the experimental groups were fed diets supplemented with 0.1%,0.2%and 0.4%Eucommia ulmoides Oliv.extract.The experiment was do-mesticated for 1 week and the formal experiment lasted for 6 weeks.At the end of the experiment,the antioxidative indexes of carassius auratus in each group were detected.The results showed that supplementation of 0.2%and 0.4%EutCHA extract significantly decreased the serum malondialdehyde level(P＜0.05),and significantly in-creased the catalase activity,glutathione peroxidase activity and glutathione-thitransferase activity(P＜0.05).The superoxide dismutase activity was significantly increased by 0.1%,0.2%and 0.4%of Eucommia ulmoides Oliv.extract(P＜0.05).The results showed that Eucommia ulmoides Oliv.extract could effectively improve the antioxi-dant function of Carassius auratus,and the optimal dosage of Eucommia ulmoides Oliv.extract was 0.2%.关键词
