Abstract: An experiment was conducted with 120 Cobb-500 Broiler day old chicks to evaluate the effect of feeding probiotic (Saccharomyces cerevisiae) with or without growth promoter (GP). Birds were reared in open sided shed type house. Body weight and feed intake were measured and examined on day 0, 7, 14, 21, 28 and 32. Chicks were randomly divided into four groups having three replications. The number of birds in each replication was 10. Four diets were considered: control; probiotic (PB) @ 1ml/liter; GP @ 100g/50kg and GP plus PB (@ 1ml/liter+ 100g/50kg). The records were kept on body weight, feed intake and mortality while weight gain, feed efficiency (FE) and survivability were calculated. Temperature and humidity were recorded four times daily. At the end of the experiment, one broiler was sacrificed from each replication to determine carcass characteristics. Broiler chicks that received PB and a combination of PB+GP treatments showed significant improvement in performance (p
