Abstract :

Abstract[1] Immunogen is a commercial prebiotic that, it’s the product of a natural combination contains several substances such as beta-glucan and mannan-oligosaccharides that are used as a food supplement in aquaculture. This study was designed to examine some immunological parameters of (Barbus grypus). 360 pieces of fingerling with an average weight 35±2 gr were randomly divided into for treatments (three replicates per treatment). Treatments respectively were diet with feed containing a immunogen with surface zero, 0/5, 1 and 1/5 for during 12 week and on days 30, 60 and 90 to measure serum laysozyme, total serum immunoglobulin levels and the bactericidal serum activity. The results showed that prebiotic immunogen causing laysozyme activity levels of treated fish showed that fish fed with 1 and 1/5 percent immunogen are higher than the control group, but the increase was not statistically significant (P>0.05). Bactericidal serum activity in the treatment of 1/5 percent immunogen in some stage of sampling was significantly increased compared with control (P<0.05). But the rate of total serum immunoglobulin did not show any significant difference (P>0.05). The results showed that different levels of immunogen prebiotic were effective on Improve the immunity response of fish (increasing activity laysozume and bacteria serum activity) So, prebiotics can be used as suitable food supplements for the dietary Barbus grypus. * Corresponding Authors; Email: [e-mail]
