Effects of heat stress in broilers


Reduced performance during heat stress in broilers is attributed to a great degree to reduced feed intake aimed at decreasing their heat increment. At increasing heat stress intensity level and duration feed efficiency is progressively reduced. This is a multifactorial effect underlined by increased oxidative stress in the intestinal tract which leads to a pro-inflammatory response. Decreased gut-barrier intergrity may lead to increased passage of luminal endotoxins and in turn lead to systemic inflammation and bacterial translocation.
