%X Experiments were carried out to observe the effect of fluctuating ambient temperature and humidity on the performance of layers inside the closed system. The study was performed at El-najah Poultry Farm (closed system) in the central region in Saudi Arabia. 360 one-day-old layer chicks (Hy-line W98) were distributed randomly into three locations A, B and C in the central floor of the central line (battery) of the rearing house. At the beginning location A, centre location B and at the end of the house location C. Each location consists of 6 replicates (A1¨CA6, B1¨CB6 and C1¨CC6). In each replicate 20 chicks were housed. Pullets were transferred to the production house in the same farm at 17th week in the similar locations mentioned above. Each location consists of 6 replicates. In each replicate 5 birds were weighed and housed. The study revealed that, birds in location B (the centre of the house), ¡ã where the temperature ranged (14-28 C) and humidity (22-90%), exhibited better performance than the other two ¡ã ¡ã locations, A and C, where temperature range (18-30 C, and 20-32 C) respectively, and humidity (30-80%, and 34- 84%) respectively. Therefore it was concluded that fluctuation of temperature inside the closed poultry house will affect the performance of laying hens.
