摘要： An 8-week study was conducted to evaluate the effects of different feeding patterns with dietaryClostridium butyricumsupplementation on growth performance, antioxidant and non-specific immune responses in freshwater prawn,Macrobrachium rosenbergii(0.39 +/- 0.001 g). There were four feeding methodologies: feeding basal diet continuously (P1); feeding diet with 500 mg/kgC. butyricumcontinuously (P2); feeding diet with 500 mg/kgC. butyricum5 days after 2 days of basal diet (P3) and feeding diet with 500 mg/kgC. butyricum2 days after 5 days of basal diet (P4). The results revealed that prawns in P3 had the highest weight gain rate (WGR) and lowest feed conversion ratio (FCR) than the other groups. Haemolymph total protein levels and superoxide dismutase activity increased significantly in P2, P3 and P4 groups, while malondialdehyde content and anti-superoxide anion levels decreased significantly compared to control. The mRNA expression of intestinal dorsal and Toll in P2 and P3 groups decreased significantly compared to control. Prawns in P3 exhibited improved growth performance, increased antioxidant capacity and enhanced immune function. We concluded that feeding diet with 500 mg/kgC. butyricumfor 5 days after 2 days of basal diet was recommended forM. rosenbergii.
