Effects of Dietary Fructooligosaccharide Supplementation on Growth Performance and Immunologic Function of Eriocheir sinensis
Abstract: The experiment was conducted to investigate the effects on growth performance and immune response of Eriocheir sinensis by supplementing diets with different doses of fructooligosaccharide (0；0.5；1.0；1.5；2.0；2.5 g/kg). Through analyzing growth performance and immune index of Eriocheir sinensis, we can select the suitable dose of fructooligosaccharides for practice. The results showed that the diet supplemented with 2.0g/kg fructooligosaccharide, in comparison with control group, can significantly improve specific growth rate and weight gain of this species. Feed efficiency of all experimental groups are less than the control group, and the experimental group supplemented with 2.0 g/kg fructooligosaccharides was significantly lower than control group (P<0.05). Blood malondialdehyde content of all experimental groups are less than the control group and the inclusion (2.0g/kg fructooligosaccharides) group was significantly lower than control group (P<0.05). The activities of CAT in crabs fed with 2.0 g/kg fructooligosaccharides was significantly higher than that in control group (P<0.05). The activities of AKP and ACP in crabs fed with 2.0 g/kg fructooligosaccharides were significantly higher than that in control group (P<0.05). These results demonstrated that 2.0 g/kg FOS supplementation might be effective in improving growth performance and immune response of Eriocheir sinensis.
