五种植物免疫增强剂对草鱼非特异免疫力的影响

在水温20～26℃下,用网箱饲养法研究了绿原酸(A组)、枸杞多糖(B组)、金丝桃素(C组)、黄芪多糖(D组)、植物血凝素(E组)对平均体重43克草鱼(Ctenopharyngodon idellus)血清超氧化物歧化酶(SOD)、碱性磷酸酶(AKP)及过氧化氢酶(CAT)活性的影响。结果显示,基础饲料中添加0.165、0.33、0.66g·kg-1的枸杞多糖;0.165、0.33、0.66g·kg-1的金丝桃素;0.165、0.66g·kg-1黄芪多糖;0.1、0.2g·kg-1绿原酸的试验组,超氧化物歧化酶的活力比对照(O组)显著增强(P0.05)。但在含免疫增强剂的试验组间差异不显著。当饲料中添加0.4g·kg-1绿原酸的试验组,超氧化物歧化酶极显著提高(P0.01)。而碱性磷酸酶、过氧化氢酶试验组与对照组无显著差异。只是金丝桃素、绿原酸使碱性磷酸酶活性有增强的趋势;植物血凝素使过氧化氢酶的活性有升高的程度。60d的饲养表明,饲料中添加适量的枸杞多糖、金丝桃素、绿原酸及黄芪多糖可以显著提高草鱼的超氧化物歧化酶活性,对增强草鱼的非特异性免疫功能具有重要作用。

Effects of five plant immunopotentiators on activities of serum superoxide dismutase (SOD),catalase (CAT), and alkaline phosphatase (AKP) in grass carp

The activities of serum superoxide dismutase(SOD),alkaline phosphatase(AKP)and and catalase(CAT) were studied in grass carp(Ctenopharyngodon idellus) juveniles of the average weight 43g in the small submerged fed the diets containing chlorogenic acid(Group A),lycium barbarum polysaccharides(Group B),hypericin(Group C),astragalus polysaccharide(Group D) and plant hemagglutin in(Group E) in 20-26 degrees Celsius.The results for 60 days showed that the superoxide dismutase activity was found significantly high...
