This study has been carried out in the animal field of the college of agricultural engineering sciences, university of Baghdad, for the period from 12/15/2021 to 1/26 /2022 for 42 d, to investigate the effect of adding different levels of ellagic acid to the diet of broilers, on some physiological characteristics &  oxidation indicators in meat compared to vitamin C in meat,  225 Ross 308 chicks were used, divided randomly to five treatments such us: T1: control group without additives to diet, &  the other T2, T3, T4 was added  ellagic  acid (0.25, 0.5 and 0.75 mg/ kg diet) respectively and T5: was added vitamin C 0.5 mg/ kg, the birds were given ellagic acid & vitamin C from day one to the end of the experiment, the study results were showed a significant differences increase (P<0.05) improved at T4 treatment in the first & second week & in T2 and T4. in the 4^th  and 5^th weeks treatment T2 was superior, to show a significant advantage of the control treatment & T1,T2 in the 2^nd week for the trait of overweight, in the 4^th and 5^th weeks the treatment T2 was superior for the total weight gain, there was an improvement in the feed conversion in 4^th week in T2, in the 5^th week the treatment T2 was superior, there was a significantly superior in T2 for total weight gain rate, there was a significant increase in the feed conversion in T1 and T4 in the 2^nd week.
