The aim of the present study was to examine effects a herbal essential oil mixture on performance broilers produced by young (30 wk) or an old breeder (80 flock. One thousand and eight unsexed day-old broiler chicks (Ross-308) originating from two flocks were randomly allocated three treatment groups 336 birds each. Dietary treatments were: control diets containing 24 mg/kg 48 mixture. There no significant dietary body weight at 21 42 days. effect age parents did not have days age. Up feed intake breeders reduced significantly as result inclusion in their diets, improvement conversion ratio recorded these birds. Difference regression coefficients for between significant. Carcass yield some internal organ weights such liver, pancreas, proventriculus, gizzard small intestine affected addition diet.
