This study was conducted to investigate the effect of fermented sesame meal on performance, carcass characteristics, blood parameters, immunity and bone mineralization in broiler chickens. A total of 525 broiler chicks were randomly allocated into 7 treatments with five replicate pens each. Lactobacillus plantarum PTCC1058 and Bacillus subtilis PTCC1156 in combination with Aspergillus niger PTCC5010 were used to ferment sesame flour. Experimental treatments include a basal diet and basal diet containing 6 or 12% fermented sesame meal and 6 or 12% untreated sesame meal with or without phytase enzyme. The treatment containing 6% USM+phytase enzyme and 12% FSM showed the highest weight gain during the starter and total phases in broilers, respectively (P<0.05). During total phase, feed conversion ratio improved in broilers fed diets containing 6 and 12% FSM and USM+phytase (P<0.05). The highest and lowest blood glucose concentrations were observed in the treatments containing 6% USM + phytase enzyme and 12% USM + phytase enzyme, respectively (P <0.05). The results of antibody titer against Gamboro and bronchitis showed that there was a significant difference in the titer against Gamboro between experimental treatments (p<0.05). The highest percentage of ash, phosphorus and calcium was observed in the treatment containing 6% FSM (P<0.05). The general result of the present study showed that the processing of sesame meal by fermentation method improved growth prformance and increased the level of antibody titer against Gamboro disease in broiler chickens. In addition, Phytase supplement in sesame meal diets improved bone mineralization in broilers.
