Effects of immunization with Aeromonas hydrophila killed by formalin and sonicated Antigen on the Growth and Blood parameters of Cyprinus carpioL.

The aim of the study was conducted to investigate the effects of immunization with Aeromonas hydrophila killed by formalin and sonicate antigen on some growth parameters (Average body weight, Average feed consumption, average and total average body weight gain, daily gain, relative gain rate, food conversion, food Conversion efficiency) and Blood parameters (RBC, HP, PCV, WBC and differential proportions of leucocyte) of Cyprinus carpioL. by used 100 fish were randomly divided into 5 groups (20 fish each group). T1 and T2 killed antigen were given via formaline (T1 0.2 ml IM injection and T2 immersion 5 Minutes), While T3 and T4 were given killed antigen via sonicasion (T3 0.2 ml IM injection and T4 immersion 5 Minutes). The control group were given 0.2 ml phosphate buffer saline intramuscularly. The results after 42 days abservation of showed no significant differences al (P≥0.05) in Growth and Blood parameters between within all Treated group as compare with control group except WBC and differential proportions of leucocyte
