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 < 0.05) in birds supplemented with herb extract compared to control birds. Mortalities and sudden deaths were minimized via herbal supplementation. However, herbal supplementation had no significant effects on carcass cuts and some visceral organs. The relative economic efficiency (REE) was up to 13% improved by the herb supplementation. It can be concluded that feeding the herbal extract has significant positive effects on broilers general performance as feed efficiency is increased by 11% and on mortality and sudden death cases.
