摘　　要：试验旨在研究不同比例残次红枣发酵饲料对克氏原螯虾(Procambarus clarkii)生长性能和肌肉品质的影响。选择720尾克氏原螯虾随机分为6组,每组3个重复,每个重复40尾。对照组饲喂基础饲料,试验组中分别添加10%、20%、30%、40%、50%残次红枣发酵饲料。结果显示,20%组的特定生长率、末重、增重率和存活率均显著高于其他组(P<0.05),饲料系数显著低于其他组(P<0.05)。10%组、20%组的肌肉粗蛋白和粗脂肪含量显著高于其他组(P<0.05)。20%组的肌肉总氨基酸和必需氨基酸含量均显著高于其他组(P<0.05),谷氨酸含量显著高于对照组和50%组(P<0.05)。研究表明,添加20%的残次红枣发酵饲料对克氏原螯虾的生长性能具有积极影响,肌肉营养价值和品质更优。The aim of this experiment was to study the effects of residual red dates fermented feed with different proportions on the growth performance and meat quality of Procambarusclarkii.A total of 720 Procambarusclarkiiwere randomly divided into six groups with three replicates per group and 40 tails per replicate.The control group was fed a basic diet,and the experimental groups were supplemented with 10%,20%,30%,40%,and 50%residual red dates fermented feed,respectively.The results showed that the specific growth rate,final weight,weight gain rate,and survival rate of 20%group were significantly higher than those of other groups(P<0.05).The food coefficient of 20%group was significantly lower than that of other groups(P<0.05).The concentrations of crude protein and crude fat of muscle in 10%group and 20%group were significantly higher than that in other groups(P<0.05).The concentrations of total amino acid and essential amino acid in 20%group were significantly higher than those in other groups(P<0.05),and glutamic acid content was significantly higher than that in control group and 50%group(P<0.05).The study indicates that adding 20%residual red dates fermented feed has a positive effect on the growth performance of Procambarus clarkii,and the nutritional value and quality of meat are also better.
