Abstract

This study was carried out to evaluate three different resources of energy; liquefied petroleum gas (LPG), biogas and electricity (lighting) used to warm poultry houses. Experiments were carried out during winter 2019. The experimented poultry house has dimensions 1.6*0.8*0.8 m for each treatment. Each treatment included 11 chicks. The brooding cycle was 39 days. by adjusting the fuel consumption automatically, the chicks were brooding at a temperature of 32 °C in the first week, in the second week temperature is set at 29 °C, in the third week a temperature set at 26 °C and in the fourth week a temperature set at 23 °C. Temperature and humidity were recorded automatically every 1 minute, also energy consumption and broiler weight were measured for each treatment. Experiments showed the warming by lighting was recorded internal humidity lower than the warming by biogas and LPG, while the LPG treatment was recorded the largest value of humidity. The total cost of warming was 100, 120 and 168 LE/cycle with LPG, biogas and lighting, at respectively; The cost of heating per hen 9.1 LE for LPG unit, 10.91 LE for biogas unit and 15.27 LE for lighting unit. The Experiments showed biogas may be a feasible nontraditional resource for warming of poultry houses especially if the organic wastes were available free at the same farm.
