Can heat stress cause pale comb on poultry?

Heat stress can cause a number of health problems in poultry, including pale comb. This is because when birds are exposed to high temperatures, their blood vessels dilate in an attempt to lose heat. This can cause the comb, which is a highly vascularized organ, to become pale.

In addition to causing pale comb, heat stress can also lead to other health problems in poultry, such as:

* Reduced egg production

* Poor growth

* Increased mortality

* Increased susceptibility to disease

It is important to take steps to reduce heat stress in poultry during hot weather. This can be done by providing shade, ventilation, and access to cool water. In some cases, it may also be necessary to use air conditioning or misters.

By taking steps to reduce heat stress, poultry producers can help to ensure the health and productivity of their flocks.
