摘要
试验旨在研究黄颡鱼(Pseudobagrus fulvidraco)幼鱼饲料中添加不同水平的还原型谷胱甘肽对其生长性能的影响,确定黄颡鱼幼鱼养殖生产中还原型谷胱甘肽的最适添加水平.选择初始体重约为 11g的健康的黄颡鱼幼鱼,按照单因素试验设计原则,将其分成 4 个处理组,每组 3 个重复,每个重复 35 尾黄颡鱼幼鱼.对照组的黄颡鱼幼鱼投喂不添加还原型谷胱甘肽的基础饲料,试验组黄颡鱼幼鱼投喂分别添加 200 mg/kg、400 mg/kg和800 mg/kg的还原型谷胱甘肽的基础饲料.试验黄颡鱼幼鱼驯养 2 周,正式试验期为 6 周.试验结束,检测各组黄颡鱼幼鱼的生长性能.结果显示,与对照组比较,黄颡鱼幼鱼投喂400 mg/kg的还原型谷胱甘肽可以显著提高试验末重(P＜0.05);投喂 400 和 800mg/kg的还原型谷胱甘肽可以显著提高增重率、特定生长率(P＜0.05),显著降低了饲料系数(P＜0.05).综上所述,黄颡鱼幼鱼养殖中添加适量的还原型谷胱甘肽可以提高其生长性能.
Abstract
The aim of this experiment was to investigate the effects of different levels of reduced glutathione in the diets of juvenile Pseudobagrus fulvidraco on their growth performance,and to determine the optimal supplemental level of reduced glutathione for juvenile Pseudobagrus fulvidraco.Healthy juvenile yellow catfish with an initial body weight of 11g were divided into 4 treatment groups with 3 replicates per group and 35 juvenile yellow catfish per replicate according to the principle of single-factor design.Juvenile Pseudobagrus fulvidraco in the control group were fed a basal diet without reduced glutathione,and those in experimental groups were fed 200 mg/kg,400 mg/kg and 800 mg/kg supplemented with reduced glutathione,respectively.Juvenile yellow catfish were do-mesticated for 2 weeks and the formal experiment period was 6 weeks.At the end of the experiment,the growth performance of juvenile Pseudobagrus fulvidraco in each group was tested.The results showed as follows:Compared with the control group,feeding 400 mg/kg reduced glutathione significantly increased the final weight of juvenile yellow catfish(P＜0.05).Diets of 400 and 800mg/kg reduced glutathione significantly increased weight gain rate and specific growth rate(P＜0.05),and significantly decreased feed coefficient(P＜0.05).In conclusion,the growth performance of juvenile Pseudobagrus fulvidraco can be improved by adding appropriate amount of reduced glutathione.
