ABSTRACT
The main objective of this study was to study some environmental factors affecting broiler housing in winter season. The results showed that, temperature fluctuations between house ceiling and floor ranged between 0.4 to 5.93 ºC during the first two days of age. The average house temperature reduced gradually from 29.7 to 21.3 ºC. The indoor relative humidity ranged between 43.6 to 74.3 %. Specific heating power, specific fuel consumption and heating energy requirements ranged between 3850.2 W/ºC , 0.34 kg /h. ºC and 308.9 kJ/h. kg at the first week of age to 6213.4 W/ºC , 0.36 kg /h. ºC and 19.3 kJ/h. kg at the end of the life respectively
