This study was conducted to evaluate the response of broiler chickens to adding graded levels (0% -0.5% -1 % -1 . 5%) of clove extract added in chick's drinking water. The study measured included production performance. 200 chicks (one day old) were used from the Cobb strain. The experiment chicks were divided into four groups, each containing 50 chicks, distributed into four treatments. The experimental feed was formulated to be isocaloric and isonitrogenous to meet the nutritional requirements of broiler chickens. The experimental groups were fed for 5 weeks and at the end of the experiment period two birds form each group were taken for slaughtered measurements. The experiment data was analyzed using a completely randomized design. The adding of clove extract to chicks drinking water was revealed a highly significant improvement (P<0.01) in the percentage of feed consumed, total body weight gained and carcass weight. The best chicks performance were obtained when adding 0.5% of clove extract.
