The present experiment was conducted to evaluate the effect of dietary supplementation of Saccharomyces cerevisiae on the growth performance of broiler chickens. A total of 120-day-old Cobb-400 broiler chicks were randomly allotted to four dietary treatments with five replications of six birds each. The treatments consisted of T₀ (control, basal diet), T₁ (basal diet + 1% yeast), T₂ (basal diet + 1.5% yeast), and T₃ (basal diet + 2% yeast). The feeding trial lasted for 42 days under uniform managemental conditions.

Results indicated that yeast supplementation significantly (P<0.05) influenced growth performance. Birds in T₂ recorded the highest final body weight (2439.96 g) and the most efficient FCR (1.90), followed by T₁ (2410.24 g, FCR 1.91). Control (T₀) and T₃ (2% yeast) showed comparatively lower performance. It was concluded that supplementation of Saccharomyces cerevisiae at 1.5% optimizes broiler growth and feed efficiency.
