    Effect of Different Housing Systems on Production and Blood Profile of Slow-Growing Broilers
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2015) Diktas, Merve; Sekeroglu, Ahmet; Duman, Mustafa; Yildirim, Arda
    Present study was conducted to investigate the effects of deep litter system, free-range with fixed housing system and free-range with portable housing system in wheat stubble on performance, internal organ weights, blood parameters and tonic immobility of slow-growing broilers. A total of 270 Hubbard Isa Red-JA chicks were used in experiments. The experiment lasted for 61 days. Results showed that the body weight on 21(st), 28(th), 35(th) and 42(th) days of birds from free-range with portable housing system was significantly lower than of those kept in deep litter and free range with fixed housing system. The viability of broilers in free-range with portable housing system was lower than broilers in free-range with fixed housing and deep litter system in the days of 14-42 and 14-61, while there were not any differences between housing systems in days of 43-61. Housing systems had no significant effect on feed conversion ratio and internal organ weight. There were no significant differences in tonic immobility durations of housing systems and some blood parameters, except hematocrit values. In conclusion, the body weight in free-range with portable housing system was significantly lower until 42nd day of the experiment, but this difference was disappeared during the rest of rearing period. It could be concluded that rural producer can be involved in broiler production after wheat harvesting.

    Effect of Free Fange Production System on Slower-Growing Broiler Carcass Characteristics and Meat Quality
    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2012) Sekeroglu, Ahmet; Diktas, Merve
    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.
