VC、VE、GABA对北方寒地克氏原螯虾抗低温应激的影响
Effects of VC,VE,and GABA on cold stress resistance in Procambarus clarkii from northern cold regions
摘要
Abstract
The experiment aimed to investigate the effects of vitamin C(VC),vitamin E(VE),and γ-aminobutyric acid(GABA)on the cold stress resistance ability of juvenile Procambarus clarkii.A total of 120 healthy juvenile Procambarus clarkii with intact appendages were randomly divided into four groups,with three replicates per group and 10 Procambarus clarkii per replicate.The control group was fed a basal diet,while the experimental groups were fed the basal diet supplemented with 0.05%VC(group VC),0.05%VE(group VE),and 0.05%GABA(group GABA),respectively.After the first week of the experiment,simulated cold stress was applied,the pre-test period was one week,and the formal test period was six weeks.The results showed that the body weight in the group VC was significantly higher than that in the control group in the 3rd week(P<0.05),the body weight in all experimental groups was significantly higher than that in the control group in the 4th week(P<0.05),and the body weight in the group GABA was significantly higher than that in the other groups in the 5th and 6th weeks(P<0.05).The weight gain rate and specific growth rate in all experimental groups were significantly higher than those in the control group(P<0.05),and the survival rates in the groups VC and GABA were significantly higher than those in the control group(P<0.05).The hepatopancreatic lipase and trypsin activities in the group GABA were significantly higher than those in the control group(P<0.05).At 24 hours after cold stress and at the end of the experiment,the hepatopancreatic immune and antioxidant indices in all experimental groups were superior to those in the control group,with the groups VC and GABA showing greater improvements than the group VE.The study shows that dietary supplementation with VC,VE,and GABA can effectively alleviate cold stress and promote growth recovery in juvenile Procambarus clarkii,with GABA and VC being superior to VE in improving growth performance,digestive enzyme activities,and immune and antioxidant capacity.关键词
