Abstract –The antimicrobial activity of essential oil is known in a empirical way since Antiquity. Essential oil is known for a long time on a clinical plan and the scientific publications are uncountable to demonstrate their efficiency, in particular their anti-infective potential. In this context, a study was made to study the effects of the treatment on the base of the extracts of lentisque pistachier plant (two various doses 100 ppm and 50ppm) on the zootechnic parameters of free-range chickens. The chickens are raised in conditions favorable to the development of the diseases. We used a size of 36 chickens of the origin " huge sponge cake " distributed in a random way on three batchs, every batch contains 12 chickens: a control batch without treatment of essential oil, and two other batchs treated with the essential oil "100 ppm " and "50ppm during all the duration of the experience which is from 15 weeks to 19 weeks. It is necessary to note that the zootechnic parameters were estimated every week on the basis of the organoleptic quality of the meat.
