Impact of high heat on poultry

Poultry are very sensitive to heat

  • Birds do not have sweat glands.
  • The body temperature of the birds is around 41°C.
  • A variation of 4°C in body temperature is lethal.
  • The regulation of heat is done by perspiration, convection and increase of the exchange surface with the air (opening of the wings for example).
  • Perspiration is a costly energy process for the animal (540 calories per gram of water in the lungs) which generates heat!

In addition to mortality, which has a direct impact on profits, heatstroke reduces zootechnical performance and amplifies economic losses:

  • 25% of GMQ
  • 20% of consumption
  • 3% CI
  • 26% increase in mortality

For temperatures of 31°C for 10 hours at 35-42 days of age (Quinteiro- Filho, 2010 & Quinteiro-Filho, 2012).
