AbstractThe research was conducted to investigate the effect of supplementation of organic acids blend to the ration on some productive and physiological traits of broiler . A total number of 300 one day old chicks( Ross 308) were used ,those chicks were randomly distributed in to 5 treatment and each treatment involved 3 equal replications. organic acids were added to the starter and finisher ration during the 2nd week of age, the first treatment fed on ordinary ration without the addition (control treatment ) mean while organic acids were supplemental as 0.5, 1.0, 1.5 and 2.0% to the second , third, fourth and fifth treatmants respectively . results illustrated a highly significant (p <0.05) surpassing of mean body weights in the 4th treatment during the 4th week of age with a significant improvement (p<0.05) of mortality rate in the 5th treatment, in addition the results indicated highly significant (p <0.01) improvement of Packed Cell Volume in the 4th and 5th treatments as well as a highly significant(p <0.01) improvement of heterophil lymphocyte ratio in the 3rd ,4th and 5th treatments.
