芦荟粉对西伯利亚鲟生长和血液生化指标的影响

Effects of aloe powder on the growth performance and plasma indices of sturgeon (Acipenser baerii Brandt)

摘要:

以体重（23.5±3.6） g西伯利亚鲟（Acipenser baerii Brandt）为对象，研究芦荟粉对其生长和血液生化指标的影响。试验共分6个处理，处理G₁~G₅组芦荟粉的添加量分别为0、0.125%、0.250%、0.500%、1.000%，处理G₆组添加25 mg/kg大蒜素作为药物对照组。饲养期为56 d。试验结果表明，与G1和G6相比，饲料中添加芦荟粉对西伯利亚鲟增重率、特定生长率、饵料系数等无显著影响（P>0.05）；当饲料中芦荟粉的添加量为0.250%和0.500%时，血浆超氧化物岐化酶活力显著提高（P<0.05）；当饲料中芦荟粉的添加量为0.125%和0.250%时，血浆丙二醛含量显著降低（P<0.05）；饲料中添加0.250%~0.500%的芦荟粉可提高鱼体的抗氧化能力；饲料中添加芦荟粉对西伯利亚鲟血浆球蛋白、谷丙转氨酶活力、血糖、补体C3、补体C4、酸性磷酸酶活力、碱性磷酸酶活力等无显著影响（P>0.05）。

Abstract:

Studies were conducted to demonstrate the effects of aloe (Aloe barbadensis) powder on the growth performance and plasma indices of sturgeon whose initial body weight was (23.5±3.6) g. The experiment was divided into 6 treatments added to the diet with 0% (G₁), 0.125% (G₂), 0.250% (G₃), 0.500% (G₄), 1.000% (G₅) aloe powder and 25 mg/kg allicin (G₆) respectively. After rearing for 8 weeks, compared with G₁ or G₆, the weight gain rate, specific growth rate, feed conversion rate of trial sturgeon of other groups were not different (P>0.05); when the addition amount of aloe powder reached 0.250% (G₃) or 0.500% (G₄), the plasma superoxide dismutase activities increased significantly (P<0.05); adding to the diet with 0.125% (G₂) or 0.250% (G₃) aloe powder, the plasma malondlaldehyde content decreased significantly (P<0.05); the antioxidant capacity of sturgeon was improved; the total protein, alanine transaminase activities, glucose, complement 3, complement 4, acid phosphatase activities, alkaline phosphatase activities and others in plasma were not different significantly (P>0.05).
