Abstract
The experimental work was held in commercial broiler house at Babil village, Menofia Governorate, latitude and longitude angles are 30.67°N and 30.98°E, respectively) during winter season of 2015in order to evaluate the performance of manufactured heating system and its effect on indoor air temperature and energy requirements. The indoor air temperature above the floor surface, indoor air relative humidity, fuel consumption, heat energy addition and specific heating power for every cubic meter of house volume were measured and specific fuel consumption also. Broilers performance evaluation was also determined in terms of live body mass. The obtained results showed that using manufactured heater in heating broiler house the weekly average indoor air temperature ranged between 31.61 to 23.26 oC at first and fifth week respectively. Whereas, the indoor relative humidity ranged between 26.15 to 52.48% at the same ages. The average heat energy addition to the house was 63.28 kW throughout the bird's life and specific heating power was 148.4 W/m 3 at the first week and reduced to be 37.07 W/m 3 at fifth week. Heating energy requirements decreased from 422.59 kJ/h.kg at the first week of age until reached to 19.45 kJ/h.kg at fifth week of age where the average broilers body mass was 2.2 kg.
