中文摘要:
      【目的】在绿色生态养殖条件下研究β-葡聚糖(β-glucan)对黄沙鳖(Truogx sinensis)幼鳖生长性能、 非特异性免疫和抗氧化指标的影响。【方法】选用体质量为 200(±10)g 的黄沙鳖幼鳖 180 只,随机分成 3 组, 每组 3 个重复,每个重复 20 只,分别投喂基础饲料(对照)和添加 200、1 000 mg/kg 剂量 β- 葡聚糖的试验饲料。 120 d 后对黄沙鳖幼鳖的增重量、体重与内脏比、内脏与肝脏比进行称量计算,并测定全血中过氧化氢酶,血清 中溶菌酶、碱性磷酸酶、酸性磷酸酶、超氧化物歧化酶活性和丙二醛含量。【结果】各组的增重量、体重与内脏 比、内脏与肝脏比差异不显著。血清中溶菌酶活性 1 000 mg/kg 剂量组显著高于对照组和 200 mg/kg 剂量组,200 mg/kg 剂量组与对照组之间差异不显著。与对照组相比,碱性磷酸酶试验组显著升高。超氧化物歧化酶活力 200 mg/kg 剂量组显著高于对照组和 1 000 mg/kg 剂量组,1 000 mg/kg 剂量组与对照组差异不显著。而酸性磷酸酶、过 氧化氢酶活力和丙二醛含量组间差异不显著。【结论】饲料中添加适量 β- 葡聚糖有助于提高黄沙鳖幼鳖的非特 异性免疫功能和抗氧化水平而不影响其生长性能。
英文摘要:
      【Objective】The effects of β-glucan on the growth performance, non-specific immunity and antioxidant indexes of young Truogx sinensis were studied under the condition of green ecological breeding.【Method】180 young Truogx sinensis with the body mass of 200 (±10)g were randomly divided into 3 groups. Three tests were performed in each group and 20 young T.sinensis were tested each time, and fed with basic feed(control group) and test feed with 200 mg/kg (G200) and 1 000 mg/kg(G1000) doses of β-glucan. After 120 days, the increased weight, the ratio of body weight to viscera and the ratio of viscera to liver of the young T. sinensis were calculated. The contents of catalase in whole blood, the lysozyme, alkaline phosphatase, acid phosphatase, superoxide dismutase activity and malondialdehyde in serum were determined. 【Result】 There were no significant differences in increased weight, ratio of body weight to viscera and ratio of viscera to liver in the tested groups. The Lysozyme activity (LYZ) in the serum of G1000 group was significantly higher than that of the control group and G200 group while the difference between the G200 group and the control group was not significant. The alkaline phosphatase(AKP) activity in the G200 group and G1000 group was increased significantly compared with the control group. The superoxide dismutase(SOD) activity of the G200 group was significantly higher than that of the control group and the G1000 group. No significant difference in acid phosphatase(ACP), catalase (CAT) activity and malondialdehyde(MDA) was observed in all groups(P >0.05).【Conclusion】 The addition of a proper amount of β-glucan in feed could help to improve the nonspecific immune function and antioxidant level of the young T. sinensis without affecting its growth performance.
