Effects of Bacillus amyloliquefaciens and Yarrowia lipolytica lipase 2 on immunology and growth performance of Hybrid sturgeon
چکیده انگلیسی
A 12-weeks feeding trial was performed to investigate the possible effects of supplementation of Hybrid sturgeon diet with Bacillus amyloliquefaciens (GB-9) and Yarrowia lipolytica lipase2 (YLL2) single or combined on immune response and growth performance of Hybrid sturgeon (Acipenser schrenkii ♂and Acipenser baeri ♀). For this aim, Hybrid sturgeons were fed with four experimental diets namely: Diet 1 (0-control), Diet 2 (5.0 g/kg GB-9), Diet 3 (4.0 g/kg YLL2), and Diet 4 (5.0 g/kg GB-9 + 4.0 g/kg YLL2), respectively. After fed with varied diets, growth performance, mucosal immune response, leukocytes immune response and serum immunological response were measured. The results indicated that supplementations of GB-9 + YLL2 resulted in a significant increase in final weight, Docosahexaenoic acid (DHA) and Eicosapentenoic acid (EPA) concentration, compared with that of control (p < 0.05). For innate immunity, the results showed that skin mucus lysozyme activity, leukocytes phagocytosis activity and reactive oxygen species level, and serum alternative complement pathway activity, peroxidase and lysozyme activity were significantly higher in supplemented groups compared to the control (p < 0.05). The highest values were recorded in fish fed both YLL2 and GB-9 with respect to the individual application. The present results suggested that the combination of these supplementation could be considered as potential feed-additives for aquaculture farmed fish.
