THE INFLUENCE OF SUPPLEMENTING ELLAGIC ACID TO BROILER DIETS ON PRODUCTIVITY AND WHITE BLOOD CELL DIFFERENTIAL COUNTS

Abstract

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.
