| Abstract | ||||
| This research was carried out to investigate the feasibility of using an evaporative cooling system to improve the productivity of broilers. Two different treatments cool and control rooms were used in the experiments. Mathematical computer program was first developed and the output results were used for designing the evaporative cooler. The system was manufactured and installed in the cool room for field tests. A comparison was carried out, afterwards, between birds grown in the two rooms for the bird performance, feed conversion ratio, and mortality rates. A cost analysis proved that the profits were 2723 and 1820 EG.P./life cycle for the cool and control rooms, respectively. The profit of birds produced in the cool room was almost 1.45 times that of birds produced in the control room. Therefore, the evaporative cooler was successfully increased the profit and appeared economically feasible to use. | ||||
