Abstract A study was carried out to investigate the effects of dietary sodium butyrate (SB) on the intestine and growth performance in chickens. Three hundred and thirty six day-old AA broiler chicks were allocated at random into four groups with six replicates each. Four groups were fed with basal diet (control) or diets supplemented with SB at the level of 500, 1000, 2000 mg/kg. Body weight gain increased linearly during the period from 0 to 21 days as the dietary supplementation of SB increased (P 0.05). The concentrations of DNA, RNA, and protein in duodenal mucosa showed negative quadratic responses to the increase of dietary SB supplementation level (P
