Effect of Individual and Combining of Adding Quercetin and Vitamin E to Diets in Productive Traits of Broiler Chickens

Abstract

The study was conducted to investigate the effect of adding quercetin and vitamin E to diets on productive performance of broiler .A total of 210 broiler chickens (Ross308)unsexed one day old chicks were randomly distributed to seven treatments with three replicates per treatment (10 chicks / replicate).Treatments were involvedT1: adding out  any addition, T2: adding 30 mg  sodium nitrate / kg,T3: adding 500 mg quercetin/ kg feed with 30 mg  sodium nitrate / kg ,T4: adding 1000 mgquercetin / kg feed with 30 mg  sodium nitrate / kg , T5: adding  250 mg  vitamin E / kg with 30 mg  sodium nitrate / kg,T6: adding 500 mg  quercetin / kg feed with 250 mg vitamin E  / kg with 30 mg sodium nitrate / kg , T7: adding  1000 mgquercetin / kg feed with 250 mg  vitamin E / kg with 30 mg  sodium nitrate / kg ,The obtained results showed that there were significant differences were detected between different treatments in productive performance traits at 42 days age of , which included live body weight, body weight gain, feed consumption and feed conversion ratio.
