The aim of this study was to compare the physical and sensory quality of the meat of layer males with fast-growing broilers at the same age when they had both access to free range and when they were fed to 49 and 90 days of age. Slow-growing ISABROWN (IB) layer males and fast-growing Ross 308 (RS) chickens were kept in free-range conditions to evaluate carcass and meat quality at 49 days and 90 days of age. Live weight, carcass yield, breast meat yield and the proportion of abdominal fat were significantly higher in RS at both ages. The proportions of fat in the breast meat were significantly lower in IB at both ages. The value of pH 24 h was significantly higher in IB and the meat was darker in these chickens. The overall acceptability was significantly better in IB at 90 days of age. The laying males are acceptable for an alternative system of poultry meat production from the aspect of meat quality. The quality was comparable or even higher in comparison with fast-growing chickens.
