A total of (120) day old Bounty Fresh colored broiler chickens were carried out in a completely randomized design to evaluate the effect of different levels of oregano leaf meal (OLM) on the growth performance at a dietary levels of 0, 3 ,6 and 9% respectively. Results showed significant in terms of cumulative feed consumption, gain weight and feed conversion ratio. Broilers given 6% of level of oregano (T3) had the heaviest body weight on the seven week of age with a mean 1955.25 grams while the lightest was those broilers without the supplementation of oregano leaf meal (T1) with a mean of 1743.75 grams. The inclusion of OLM as fed diet were the most efficient feed converter and therefore, has the potential to increase rapid growth and improve vitality and livability of colored broiler chicken. Insignificant result was obtained in terms of the percentage rate of growth, dressing percentage with and without giblets and feed conversion ratio as revealed by the analysis of variance. However, in terms of the income over feed and chick costs, Colored broiler chicken fed with 6% oregano leaf meal had the highest return of Php 88.89 and the lowest return was those broilers without oregano with a return of Php 50.47.The results suggest that OLM at 6% level can be safely used as feed ingredients to the broilers without any deleterious effect.
