In order to study the effects of Synbiotic Biomin IMBO as microbial feed additive on growth performance, body composition, hematological and serum biochemical parameters four experimental diets differing in Biomin IMBO levels were prepared (0.0, 0.5, 1 and 1.5 g kg-1). Moreover, numbers of 216 Common carp (Cyprinuscarpio) average weight 4.3±0.1 g were stocked in 12 tank and 18 fish in each tank. According to the results, the best final weight, weight gain rate (WGR %), specific growth rate (SGR), food conservation ratio (FCR) and protein efficiency rate (PER) were significantly (P<0.05) higher in the fish fed 1 g kg-1 Biomin IMBO supplemented diet. There was no significant difference (P>0.05) in carcass dry mater in fish fed Biomin IMBO compared to control group.

Highest carcass protein and lowest carcass lipid content were detected in fish fed 1 gkg-1 Biomin IMBO (P<0.05). Dietary supplemented with Biomin IMBO had no effect on red blood cell counts (RBC), mean corpuscular volume (MCV), mean cellular hemoglobin (MCH) or mean cell hemoglobin concentration (MCHC) (P>0.05). However, hematocrit (Htc), hemoglobin (Hb) concentration and leucocyte (WBC) levels increased in fish fed 1 and 1.5 gkg-1 Biomin IMBO (P>0.05). Among serum biochemical parameters albumin increased in 1g kg-1 and glucose increased in 0.5 and 1 g kg-1 Biomin IMBO supplemented diet. Serum cholesterol and globulin were significantly lower in 1, 1.5 g kg-1 and 0.5, 1 g kg-1 Biomin IMBO supplemented diet respectively (P<0.05). Our results suggest that diets supplemented with Biomin IMBO improved growth performance, carcass composition, hematological and some serum biochemical parameters of Cyprinuscarpio.
