Middle East has experienced an excessive temperature this summer and this affected the poultry industry and caused giant losses in farms and hen houses. In our region, as a general rule, the area fro rearing is 10 birds/m2 for broilers, 8 birds/m2, and 5 birds/m2 for broiler breeders. The natural summer temperature in our country is 29-33°C. We can control it with ventilation and cooling but this case is out of control. The results were: In Broilers: Mortality is 30-50 and decreasing in the weight gain about 10 the price of 1kg was 1.78 $ after increasing of temperature the price of 1kg is 2.28$. In Egg Layers: Mortality is 15-20 and decline in egg production by 20. In Broiler Breeders: Mortality is 10 and decline in egg production and hatchability. The intervention strategies: 1- Change the feed texture to compensate the depletion of energy and other feed ingredients. 2- Change the ventilation system in the hen house. 3- Used of antipyretic (such as aspirin) to decrease internal bodys temperature. 4- Choose the convenient vaccination applied time (at cooler time in day such as early morning). 5- Decreasing the density of population in the farm. 6- The cleanness of the air in the hen house (the birds cooling themselves by evaporation and they use their trachea to do it -all we know the birds had not any sweat glands- and if the air is contaminated with rious organisms such as E.coli the birds would be infected).

Is practical to add blocks of ice to the main water tank during the peak of hot hours ?
