In this study, meat production performance of male chicks of the ATAK-S genotype, which is anegg-yielding line, were examined in both indoor and free range raising systems. The study wascarried out at the Kahramanmaras Sutcu Imam University (KSU), Animal Production Applicationand Research Centre for 12 weeks. Each treatment was represented by 3 replications containing of28 male chicks (84 male chicks per treatment). During the indoor treatment, the chicks were raisedin floor pens in a conventional house (3.7 birds/m2). In the free-range treatment, the chickens werehoused in a similar indoor house (3.7 birds/m2); in addition, they also had a free-range cloverpaddock (0.9 birds/m2). All birds were provided with the same diets as ad-libitum. Results showedthat the thigh rate of the chickens in the free-range treatment were higher than that of the chickensin the indoor floor treatments, but the neck rate of the chickens in the free-range treatment werelower than that of the chickens in the indoor floor treatments. There was no significant effect ofthe free-range raising system on live weight, feed intake, feed conversion ratio, survival rate,eviscerated carcass, breast, thighs, wings, back rates, edible giblets, testes weight, rectaltemperature and tonic immobility.
