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

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).
