Özet
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.
