蟋蟀粉替代部分鱼粉对瓦氏雅罗鱼幼鱼生长性能、消化酶活性和肝脏抗氧化的影响OA
Effects of partial replacement of fish meal with cricket meal on growth performance,digestive enzyme activities,and liver antioxidant capacity in juvenile Leuciscus waleckii
[目的]寻找可替代鱼粉的昆虫蛋白源是当今水产动物营养研究的热点.本文旨在研究添加蟋蟀(Gryllulus)粉对瓦氏雅罗鱼(Leuciscus waleckii)幼鱼生长性能、体成分、消化酶活性和肝脏抗氧化的影响.[方法]选取 450 尾平均初始体质量为(16.27±0.05)g的瓦氏雅罗鱼进行为期 56 d的养殖实验.实验饲料中蟋蟀粉替代鱼粉的比例分别为 0%(P0,对照组)、5%(P5 组)、10%(P10 组)、15%(P15 组)和 20%(P20 组).[结果]1)养殖实验结束后,与P0 组相比,各实验组的终末体质量(FBW)、增重率(WGR)、特定生长率(SGR)和饲料系数(FCR)无显著差异;而P20 组脏体比(VSI)显著下降(P<0.05).2)各实验组间全鱼体成分(水分、粗蛋白质、粗脂肪和粗灰分)含量无显著差异.3)与P0 组相比,各实验组的脂肪酶和胃蛋白酶活性显著升高(P<0.05);P20 组 α-淀粉酶活性显著高于 P0 组和其他实验组(P<0.05).4)P15 组肝脏中丙二醛(MDA)含量显著低于P20 组(P<0.05);P10、P15 和P20 组肝脏的过氧化氢酶(CAT)活性与P0 组相比显著增加(P<0.05).[结论]在本研究条件下,蟋蟀粉替代适量比例的鱼粉对瓦氏雅罗鱼幼鱼的生长性能没有负面影响,且能提高肠道消化酶活性和肝脏抗氧化能力,其中以添加比例 15%效果最好.本研究结果可为瓦氏雅罗鱼幼鱼鱼粉配合饲料和低鱼粉饲料的开发与应用提供数据支撑.
[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.
