A total 180 day-old straight run chicks of Cobb strain were distributed randomly into four groups (with 3 sub groups of each) and were provided antibiotic free basal ration alone, T 1 or supplemented with A. indica (0.15%). T 2, Virginiamycin (20ppm) T 3, Zinc bacitracin (20ppm). At the end of 6 th week revealed non-significant differences in body weight. In all the treatment groups feed intake was significantly higher at 1 st, 3 rd, 5 th week only. Although the cumulative feed intake & FCR was non significant, however, the treated groups utilized feed more efficiently. The livability percentage and performance indices were numerically higher in the treated groups than in control group.
