The effect of synbiotic in broiler diets on productive performance, intestinal histomorphology and carcass quality was investigated. Jerusalem artichoke (Helianthus tuberosus L.) and BACTOSAC-P® were used as synbiotic sources, respectively. Four hundred Ross 308 chickens were assigned into a Complete Randomized Design (CRD) with 4 replicates (25 chickens per replicate). There were four dietary treatments: control diet (T1), synbiotic supplemented 0.025 % of DM (T2), 0.050 % of DM (T3) and 0.075 % of DM (T4) in broiler diets, respectively. A data was collected at 42 days old for productive performance, intestinal histomorphology, and carcass qualities. Jerusalem artichoke and BACTOSAC-P® were used at ratio 1:9 (w/w) at the sources of prebiotic and probiotic, respectively. The results showed that feed intake were significantly different (p<0.05), specifically with the supplementation of synbiotic at 0.05% of DM. Use of synbiotics at higher levels were affected on decrease feed conversion ratios (P<0.05) in all the groups are synbiotic supplementation. And dietary supplementation of 0.05% of DM synbiotic significantly (P<0.05) increased the villus height. Moreover, it was found that decrease ammonia concentration in the intestinal and found a decrease of visceral fat was with synbiotic 0.05% of DM (P<0.05) of chicken feed supplementation of synbiotic were not affected on crypt depth, lactic acid bacteria, carcass quality and meat quality. Based on this study, it was concluded that supplementation of synbiotics could improve FCR and reduce ammonia concentration in the intestinal tract.
