Effects of partial replacement of fish meal with cricket meal on growth performance,digestive enzyme activities,and liver antioxidant capacity in juvenile Leuciscus waleckii
摘要
Abstract
[Objective]The search for insect protein sources as alternatives to fish meal is a current hot topic in aquaculture nutrition research.This study aims to investigate the effects of dietary cricket meal supplementation on the growth performance,body composition,digestive enzyme activities,and liver antioxidant capacity in ju-venile Leuciscus waleckii.[Methods]A total of 450 juvenile L.waleckii with an average weight of approxim-ately(16.27±0.05)g were subjected to 56 days feeding trial.Experimental diets included cricket(Gryllulus)meal replacing fish meal at levels of 0%(P0 control group),5%(P5 group),10%(P10 group),15%(P15 group),and 20%(P20 group).[Results]1)At the end of the feeding experiment,compared with the control P0 group,no significant differences were observed in final body weight(FBW),weight gain rate(WGR),specific growth rate(SGR)and feed conversion ratio(FCR)among all the experimental groups;however,the viscerosomatic in-dex(VSI)in the P20 group significantly decreased(P<0.05).2)There were no significant differences in the whole-body composition(moisture,crude protein,crude lipid,and crude ash)among all the groups.3)Com-pared with the control P0 group,the activities of lipase and pepsin in all experimental groups were significantly increased(P<0.05);the activity of α-amylase in the P20 group was significantly higher than that in the control P0 group and the other experimental groups(P<0.05).4)The malondialdehyde(MDA)content in the liver of the P15 group was significantly lower than that in the P20 group(P<0.05);the catalase(CAT)activity in the liver of the P10,P15,and P20 groups was significantly higher than that in the control group P0(P<0.05).[Conclusion]Under the conditions of the study,the replacement of fish meal with an appropriate proportion of cricket meal does not negatively affect growth performance of juvenile L.waleckii,but enhances intestinal di-gestive enzyme activities and liver antioxidant capacity,with the 15%replacement level showing optimal ef-fects.These findings provide data support for the development and application of fish meal-based diets and low-fish meal formulated feeds for juvenile L.waleckii.关键词
