摘要：
The main objectives of this study were to provide thermal comfort environment, reduce heating for energy requirements and specific heating for power and maximize meat production. The air heating system performance was evaluated under with and without duct during the life cycle of 1 to 5 weeks of age. The results showed that, at first brooding stage using forced-air heating system without perforated poly - ethylene tube the air temperature at height of 0.25m above floor the air temperature close to the floor was lower than the recommended by 4.11 degrees C and 4.64 degrees C at 2 and 8 day of age, respectively. While, using it with perforated poly ethylene tube the air temperature close to the floor was higher than the recommended temperature by 0.12 degrees C and lower than the recommended by 3.36 degrees C at 3 and 8day of age, respectively. Average indoor air relative humidity through the birds' life when using heater with perforated poly-ethylene tube reduced by 12.92% comparing with using heater without perforated polyethylene tube. Using perforated poly - ethylene tube reduce total energy requirements and specific heating power by 17.84 and 20.82% at the end of life and increased average body weight from 1.9 to 2.1 kg at fifth week of age. Hence, it is recommended to operate forced - air heating system using perforated poly - ethylene tube to obtain thermal comfort environment, reduce heating energy requirements, and specific heating power and maximize meat production
