The study aimed to examine the synbiotic effects of Pediococcus acidilactici (PA) and isomaltooligosaccharide (IMO) on the growth and immunity of juvenile common carp. The results showed that the diet supplemented with 1 g/kg PA and 5 g/kg IMO significantly improved the growth performance and immune responses of the fish. Therefore, the combination of PA and IMO can be recommended as a beneficial synbiotic additive and immunostimulant in juvenile common carp.
The aim of this study was to investigate the synbiotic effects of Pediococcus acidilactici (PA) and isomaltooligosaccharide (IMO) on the performance of juvenile common carp (Cyprinus carpio). A total of 360 fish (17.22 +/- 0.19 g) were randomly divided into six groups with three replicates of 20 fish each. The trial continued for 8 weeks. The control group was fed only basal diet; PA was fed basal diet supplemented with 1 g/kg (10(10) CFU/kg) PA, IMO5 (5 g/kg IMO), IMO10 (10 g/kg IMO), PA-IMO5 (1 g/kg PA and 5 g/kg IMO), and PA-IMO10 (1 g/kg PA and 10 g/kg IMO). The results indicated that the diet containing 1 g/kg PA and 5 g/kg IMO significantly increased the fish growth performance and decreased the feed conversion ratio (p < 0.05). Overall, blood biochemical parameters, serum (lysozyme, complements C3 and C4) and mucosal (protein, total immunoglobulin, and lysozyme) immune responses, and antioxidant defense of fish also improved in the PA-IMO5 group (p < 0.05). Therefore, a combination of 1 g/kg (10(10) CFU/kg) PA and 5 g/kg IMO can be recommended as a beneficial synbiotic additive and immunostimulant in juvenile common carp.
