中文摘要:
      研究了饲料中不同添加浓度的黄芪多糖(0%、0.2%、0.4%、0.8%)对克氏原螯虾生长和非特异性免疫指标的影响。结果表明,在0 d、2 d、4 d、6 d、8 d、12 d、16 d、20 d,不同浓度组的克氏原螯虾增重率(RWG)及特定生长率(RSG)的变化规律符合修正的高斯模型(R2=0.999 9);当黄芪多糖的添加浓度为0.40%~0.75%时,实验虾的增重率、特定生长率达到最大值,分别为37.13%±7.75%和1.57%±0.28%;不同添加浓度的黄芪多糖对克氏原螯虾蜕壳数NM的影响符合对数模型(R2=0.9976),实验组与对照组的蜕壳数有显著差异(P<0.05),体重增长有极显著差异(P<0.01)。非特异性免疫指标检测发现,超氧化物歧化酶(SOD)、酸性磷酸酶(ACP)随黄芪多糖浓度变化差异不显著(P>0.05);黄芪多糖浓度对溶菌酶(LSZ)的影响极显著(P<0.01)。本实验表明,黄芪多糖对克氏原螯虾的生长和非特异性免疫具有明显的促进作用,建议黄芪多糖在饲料中的最适添加浓度为0.40%~0.80 %。
英文摘要:
      This experiment researched the effects of Astragalus Polysaccharide (APS) on the growth and non specific immune parameters of Procambarus clarkii, with different additive concentrations (0%, 0.2%, 0.4% and 0.8%). Results showed that, 0, 2, 4, 6, 8, 12, 16, 20 d, weight gain ratio (RWG) and specific growth ratio (RSG) of the crayfish fitted the modified Gauss model well (R22=0.999 9). At the concentration of 0.40%-0.75%, RWG and RSG reached the maximum values of 37.13% ± 7.75% and 1.57% ± 0.28% respectively. Curve of crayfish molt count (NM) was consistent with the log normal model (R2=0.997 6), with significantly different between experimental and control groups (P<0.05), and weight gain was also significantly different (P<0.01). Non specific immune parameters of superoxide dismutase (SOD) and acid phosphatase (ACP) changed with APS isn’t significantly (P<0.001).vely promote the growth and non specific immunity of crayfish. In addition, the suitable additive concentration was 0.40%-0.80%.
