Abstract :
The present work was carried out at EL-Gabal EL-Akhdar region Bayda city, Libya. The objective of this work is to develop a simple computer program for defining the brooding energy of broiler houses under region conditions. The simple program written using MATLAB Version 12.0. Heat bird and heat losses for each of ventilation and a sensible heat for building were identified as the main parameters in investigated program. The program can predict the maximum brooding energy for broiler house under different weather conditions and expect number of brooding heaters. The results showed that the brooding energy per one day for old chickens were found to be 4.84, 4.03, 3.22, 2.42 and 1.61 W/bird at external house temperature 10, 15, 20, 25 and 30ᵒC respectively. Whereas, the total brooding energy were recorded 10.56, 8.30, 6.04, 3.79 and 1.53 W/bird for birds at external house temperature 10, 15, 20, 25 and 30ᵒC respectively. The top score of ventilation rate for broiler house was 40690 m³/s.
