Abstract
The number of sheep in Egypt was estimated in 2013 to be 5.45 million head. But it’s decreased productivity in recent years due to the extremely high air temperature. This is considered one of the reasons leading to this. Therefore, to the protection of sheep and its increase productivity should be providing housing which achieving of the sheep engineering and environmental requirements. This research was conducted to study the effect of roofing material type and height on thermal response and productive of sheep. Carried out An experiment at agricultural experimental station, Fac. of Agric. Cairo univ., Giza, Egypt, on 30 Barki sheep (20 Ram and Ewe lambs, 10 yearling ewes). The two types of housing were tested .housing of concrete roofing, housing of iron sheet roofing. The measured indicators of houses: dimensions, orientation of houses, roofs, walls and floors temperature, climatic conditions (air temperature, relative humidity and air velocity) inside and outside housing
