Abstract

The experimental work was carried out in private broiler house at Babel village, Menofia Governorate, during the winter season of 2011 in order to reduce the temperature stratifications that usually occurred in the broiler housing when using forced air heating system with and without perforated polyethylene duct. The air temperatures just above the floor surface and underneath the ceiling ambient floor and ceiling were continuously measured. The broiler performance evaluation was also determined in terms of feed conversions efficiency, production index, and efficiency rate of production. The obtained results showed that, when using forced air heating without polyethylene duct temperature stratification ranged between 0.4 and 5.93 ºC. Whereas, employing the forced air furnace with perforated duct, led to minimize the temperature stratification to -2.9ºC and 0.043ºC during the first two days age. Using forced air furnace with perforated duct increased feed conversions efficiency, production index and efficiency rate of production from 60.4 to 65.2 %, 114.8 to130.6 % and from 306.83 to 347.06%, respectively. While, the feed conversions ratio decreased from 1.65 to 1.60 after five weeks age.
