   This experiment was conducted to investigate the effects of supplementation of different levels of peribiotic of mannan oligosaccharide (MOS) (Celmanax) on performance and some blood parameters of broiler chicks under induced ascites. 320 day-old Ross 308 male chicks were randomly divided into 4 treatments with 4 replicates. The dietary treatments included: positive control (corn – soybean meal basal diet), negative control (induced ascites with sodium chloride supplementation in the drinking water), negative control with supplementation of (2 and 4 ml per liter of drinking water of mannan oligosaccharide. Feed intake, Body weight and feed conversion ratio were measured at the end of the experimental period (42 d). Dead birds were dissected for ascites symptoms. Blood and ascites parameters (Right ventricular weight to total ventricles ratio (RV/TV) were also measured at 42 days of age. The statistical analysis of the data was done by using SAS software and comparison of the means were done by Tukey test at a significant level of 5%. The results showed MOS increased weight gain and decreased feed conversion ratio in birds with ascites (P <0.05). Both MOS levels significantly decreased the hemoglobin, red blood cells count, protein and hematocrit content of  birds reared under induced ascites (P <0.05). In addition, supplementation of 4cc/l  MOS on drinking water significantly decreased mortality rate caused by ascites (3.3%) and RV/TV index (P <0.05). In Conclusion, the supplementation of 4 cc MOS per liter of drinking water can improve growth performance of broiler chickens and can reduce the mortality rate of chickens reard unedr induced ascites.
