ABSTRACT: The objective of this research was to investigate the effects of a natural herb extract on the general performance, carcass parameters and mortality of broiler chicks. A total of 720 one-day old chicks (Cobb 500) were used in the experiment and randomly partitioned into nine pens (80 chicks per pen). Three experimental diets (C: regular starter feed; CC plus: regular starter feed supplemented with chicken plus herbal extract; AFC plus: antibiotic-free diet supplemented with chicken plus) were assigned each to three randomly selected pens. The herbal extract was supplemented in drinking water at rate of 300 ml/cubic meter. Results showed that weights, feed conversion ratios (FCR) and dressing percentages (DP) increased (P
