中文摘要：
以体重（23.5±3.6）g西伯利亚鲟（Acipenser baeriiBrandt）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G1和G6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）。
英文摘要：
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（P0.05）;when the addition amount of aloe powder reached 0.250%（G3） or 0.500%（G4）,the plasma superoxide dismutase activities increased significantly（P0.05）;adding to the diet with 0.125%（G2） or 0.250%（G3） aloe powder,the plasma malondlaldehyde content decreased significantly（P0.05）;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（P0.05）.
