Abstract This experiment was conducted to investigate the effects of Bacillus coagulans on the growth performance and immune functions of the intestinal mucosa of yellow broilers. Three hundred and sixty one-day-old yellow chicks were randomly allocated to four treatments groups with six replicates of 15 chicks each. The broilers were randomly subjected to one of the following treatments for 28 days: control group (group1, fed a basal diet) and three treatments (group 2, 3, 4) fed the basal diet supplemented with 100, 200, or 300 mg/kg Bacillus coagulans, respectively). The results showed that for 28 days, compared with the control diet, the dietary addition of 200 mg/kg Bacillus coagulans significantly decreased the feed/gain ratio (F/G) (p
