| Abstract | ||
| Heat stress (HS) is one of the most important environmental stressors challenging poultry production worldwide. This study aimed to measure the relationship between the biosecurity measure which applied in poultry farms and the effect of heat stress severity. We collected of 120 blood and 24 tissue samples to show the effect of heat stress on blood parameters and some histopathological changes. There were a direct relationship between biosecurity level and heat stress on egg production and FCR. The egg production was the highest in layer farm B with biosecurity (90%) as well as the FCR was the highest in farm A with biosecurity (62.5%). In addition to the heat stress effect on blood in poultry. Serum glucose was the highest in layer farm A and broiler farm B, thyroid hormone triiodothyronine (T3) was the highest in layer farm A and broiler farm A, thyroxine (T4) was the highest in layer farm B and broiler farm A. Furthermore, the level of cortisol was the highest in layer farm A and broiler farm A. There were some histopathological changes in liver and intestine. Finally, we concluded that efficient heat stress control through strong biosecurity plan relieves the HS effect and maintains high FCR and egg production. | ||
