This study was conducted to compare the performance of 25,000 and 40,000 capacity cabinet systems in meat chickens, the effects on some blood parameters, bone quality, Musculus pectoralis pH levels, and cornea defects. For this purpose, 25,000 and 40,000 capacity sets were followed simultaneously throughout four production periods. At the end of the four production periods, a total of 20 chickens were selected, balanced with living weights from each capacity. The pimples were cut by the neck method, the blood was taken. The pH of the breast muscle is measured at the end of 10 minutes. The bones were stolen from the meat and analysed. A total of 300 chickens from each feature were studied to assess the defects of the carcass. The research groups showed similar values in terms of living weight, food consumption, food use and death rates. There is no statistical difference in serum glucose, cholesterol, VLDL cholesterol, triglyceride, protein, uric acid levels and alkaline phosfatase and creatine kinase enzyme activities. The physical characteristics of the Tibio-tarsal bone and the mineral level are similar to the physical characteristics of the femur bone in groups. The pH of the chest muscle is within dark, hard, dry (KSK) meat limits, but statistical differences between the research groups have not been found. The wing wreckage rate was significantly high in the 40,000-capacity group (P<0.01). Similar rates have been obtained in cases of wings breaking, chest mourning, incis and baget mourning. As a result, it has been found that the cabin system has similar production characteristics in the studied quantity sizes.
