This study was aimed at studying the impact of the free-range hosting system on growth performance and economic efficiency in slow and rapidly developing meat chickens. The study included four main groups (2x2) and each main group consisted of five repeated groups, including free range and the traditional deep ground system, with two separate meat chicken genotypes developing slowly and rapidly. In each repeated group, the study, which includes 10 pets, used a total of 200 pets of male pets in a daily age, the live weight, food consumption and deaths in the groups were recorded, variable expenses and the share in the total of these expenses were determined, the gross profit and profit rate were calculated. The study ended (56 days of age) with a living weight (P<0. The impact of the housing system was significant in terms of 009) and the feed use rate (P<0.01) and the test end of the fast-growing genotypes was higher than the living weight (P<0.001) and the feed use capacity (P<0.006) of the slow-growing genotypes. In general, both slow and rapidly developing chickens in the free-range housing have been found to have higher growth and economic performance than those grown in the deep submarine system. According to the results obtained, it is expected that the use of rapidly developing chicken in the free-range chicken meat production, the use of slowly developing chicken in the conventional chicken meat production, will become increasingly widespread.
