The study was carried out to evaluate the effect of Saccharomyces boulardii (Sb) on performance and intestinal integrity in broilers.  A total of 300 day old Vencobb chicks were randomized in 5 groups, each with 6 replications (5x6) 10 birds per replicate. Groups provided with Sb ( 2 × 108 cfu/kg) in 0,0.02,0.04,0.08 and 0.16 mg/L in D1, D2, D3, D4, D5 respectively through water up to 42 days of age with adlibitum isonitrogenous and isocaloric ration. The results revealed, a significant (p<0.05) improvement in body weight gain, better FCR with increased concentration of Sb in water (D5). No significant variation was observed in feed intake with the level of Sb in water. Intestinal villus height, cryptal depth increased in groups with increased Sb. The results suggest that supplementation of Sb  at 0.16mg/L through drinking water  improved  the performance of the broilers by increasing the absorption capacity in the gut.
