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 (p<0.05),but has not any effect on breast,back and neck ratios (p>0.05). 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 (p<0.01). while there was a significant difference between production systems in terms of monounsaturated fatty acid miristoleik acit (p<0.5),there were any significant difference in terms of other fatty acids (p>0.05). 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.
