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 : T 1 : control group without additives to diet, & the other T 2, T 3, T 4 was added ellagic acid (0.25, 0.5 and 0.75 MG / KG diet) respectively and T 5 : 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 T 4 treatment in the first & second week & in T 2 and T 4.

in the 4th and 5th weeks treatment T 2 was superior, to show a significant advantage of the control treatment & T 1, T 2 in the 2nd week for the trait of overweight, in the 4th and 5th weeks the treatment T 2 was superior for the total weight gain, there was an improvement in the feed conversion in 4th week in T 2, in the 5th week the treatment T 2 was superior, there was a significantly superior in T 2 for total weight gain rate, there was a significant increase in the feed conversion in T 1 and T 4 in the 2nd week.
