Abstract

IMPROVE THE PRODUCTIVE PERFORMANCE OF LAYING HENS BY MAXIMIZING THE EFFICIENCY OF THE COOLING SYSTEM BY EVAPORATION UNDER THE CLIMATIC CONDITION OF THE DELTA During summer season, high temperature contributes to heat stress, which has very board effects on laying hen’s behavior and physiology. Therefore, the heat stress reduction is main goal for indoor climate control. Evaporative cooling systems are a useful tool that has long been recommended to increase laying hens comfort under hot weather. So, pad-fan evaporative cooling systems are employed in laying hens housing in this present study.
