Effects of Lycium barbarum Polysaccharides on Growth Performance,Antioxidant Capacity and Immunologic Function of Channa argus
摘要
Abstract
In order to study the effects of Lycium barbarum polysaccharides(LBP)on the growth performance,antioxidant capacity and immunologic function of Channa argus,540 Channa argus with an initial body weight of(10.12±0.15)g were randomly divided into 6 groups,each group with 3 replicates,and fed with the experimental feed with the content of LBP of 0,500,1 000,1 500,2 000,2 500 mg/kg for 8 weeks.The results showed as follows:compared with the control group,dietary supplementation with LBP at various levels significantly enhanced the average weight gain rate,specific growth rate,feed efficiency,and protein efficiency(P<0.05).Serum superoxide dismutase activity was significantly elevated in all treatment groups compared to the control group,with the highest activity in the 1 500 mg/kg group(P<0.05).The catalase activity in 1 000 and 1 500 mg/kg LBP groups was significantly higher than that in control group(P<0.05).No significant differences were observed in glutathione peroxidase activity and malondialdehyde content among all groups(P>0.05).The serum lysozyme,alkaline phosphatase,acid phosphatase and immunoglobulin M in the 1 500.and 2 000 mg/kg groups were significantly higher than those in the control group(P<0.05).Complement C3 and C4 levels were significantly increased in the 1 000 mg/kg group compared to the control group(P<0.05).These results indicate that LBP can significantly improve the growth performance,antioxidant capacity and immunologic function of Channa argus,and the best effect is obtained with the addition of LBP at 1 500 mg/kg in Channa argus feed.关键词
