Effect of free fange production system on slower-growing broiler carcass characteristics and meat quality [Yavaş gelişen etlik piliçlerin karkas özelliklerine ve et kalitesine serbest yetiştirme sisteminin etkisi]

The experiment was conducted to study the effect of deep litter system, free-range with fixed housing system and free-range with portable housing system in wheat stubble on carcass characteristics and meat quality of slow-growing broiler chickens. The number of 270 slow-growing Hubbard Isa Red-JA chicks was used in experiment. Number of 12 slow-growing broilers from each production system and totally 36 slow-growing broilers was selected for detection of carcass and meat quality characteristics. Results showed that production system has a significant effect on carcass yield, leg and wing ratios (P0.05). Production system was also not effected in terms of pH, color, protein content, fat, ash, dry matter and water holding capacity of breast meat (P>0.05), but has a significant effect in terms of polyunsaturated fatty acids of breast meat (P0.05). Free-range with fixed housing system has an advantage than other systems in terms of nutrient content, polyunsaturated fatty acids and monounsaturated fatty acid miristoleik acit of breast meat
