Abstract
An experiment was undertaken at Abu-Ghraib to the west of Baghdad to investigate the ability of using best kinds of pads (fillings) used in poultry farms. Three kinds of fillings were used; palm fiber filling, cellulose filling, in addition to the plastic mesh filling. Filling thickness (5cm). This study was performed in a poultry farm belonging to the College of Agriculture – University of Baghdad during the summer 2005. This was to measure temperature, internal-external dew point, static pressure and air speed .The efficiency of cooling for the pads used was calculated through a certain formula. The measurement was taken during the day time from 10:00 am - 4:00 pm. A factorial experiment with a completely randomized design with three replicates was used. There was no effect of time on cooling efficiency when kinds of pads affect on cooling efficiency the highest degree was 92.97% when using palm fiber at 4 pm and the least was 38.40% when using plastic mesh at 4 pm. The variation kind of pad effects on a static pressure, when the highest 0.21 when using plastic mesh and the lowest was 0.09 when used palm fiber. The decrease in temperature, when using pad filling, was 28.88 Cْ while outside degree was 43.04 Cْ. There was no effect of time on air speed during the pads. So that, the pads were suitable for the day time and the best kind of pads was the leaf palm which gave higher cooling efficiency.
