五倍子对斑点叉尾鮰生长性能、生理代谢及组织成分的影响
Effects of Galla chinensis on growth performance,physiological metabolism,and tissue composition of Ictalurus punctatus
摘要
Abstract
This experiment aimed to investigate the effects of Galla chinensis on the growth performance,physiological metabolism,and tissue composition of Ictalurus punctatus.A total of 240 healthy juvenile fish with an average initial body weight of(11.81±0.57)g were randomly divided into four groups,with three replicates per group and 20 fish per replicate.The groups S0,S5,S10,and S20 were fed basal diets supplemented with 0,5,10,and 20 g/kg of Galla chinensis,respectively,formulated to be isonitrogenous and isolipidic.The pre-test period was two weeks,and the formal test period was eight weeks.The results showed that compared with the group S0,the weight gain rate and specific growth rate were significantly increased in the group S10(P＜0.05).Serum triglyceride and total cholesterol concentrations were significantly decreased in the groups S10 and S20(P＜0.05),while the glucose content was significantly increased(P＜0.05).The total antioxidant capacity(T-AOC)and the activities of superoxide dismutase(SOD),alkaline phosphatase(AKP),and acid phosphatase(ACP)in the serum of group S10 were significantly increased(P＜0.05),whereas serum malondialdehyde(MDA)content was significantly decreased(P＜0.05).The crude protein content in the hepatopancreas of the groups S10 and S20 was significantly increased(P＜0.05),while the crude fat content was significantly decreased(P＜0.05).The study shows that dietary supplementation with 10 g/kg Galla chinensis effectively improve the growth performance,enhance immune and antioxidant functions of Ictalurus punctatus.关键词
