Two experiments were conducted to evaluate the effects of dietary essential oil mixture supplementation (eom) on the performance,carcass yield and some organ weights of broilers. a total of 400 one-day-old broiler chicks (ross-308) per one experiment were randomly assigned to 2 groups. half of the broilers were given untreated basal diets while the remaining birds were fed on the basal diet supplemented with eom containing a blend of six essential oils. dietary eom supplementation did not promote growth in the experiment 1 (p>0.05),while eom increased body weight and improved feed conversion ratio between 0-3 and 0-6 weeks in the experiment 2 (p<0.01). feed intake and mortality was not affected by eom supplementation in both trials (p>0.05). supplementation diet with eom increased carcass yield in the experiment 1 (p<0.05). in addition,pancreas weight was increased in response to eom in the second trial. overall results showed that an eom can be used as performance enhancer in broiler diets.
