The present work was designed to study the effect of using some untraditional energy sources produced in north Sinai on the performance and physiological characteristics of broiler chicks under north Sinai environmental condition. In this respect, yellow corn, as the main source of energy, was substituted by olive pomace meal and orange west meal at rate 3, 6 and 9%, each alone in different diet formulated on the basis of economic efficiency and iso-nutritive value. A total number of 400 one day old Hubbard broiler chickens were brooded up to 45 day of age. Chicks were given iso-nitrogenous and iso-caloric diets and assigned in two stages of growth. The started from 7 to 28 day old, while the second was durated from 28 until 45 day of age. The results indicated that the waste product from the manufacture of orange west meal at rates of 9% and 6% and olive pomace meal 6% without the occurrence of any side effects either on production performance or physiological characteristics of  the bird as those ratios achieved the best results in terms of production and economic efficiency, the proportions of the rate, respectively.
