Discuss about the feeding of poultry birds in extreme weather conditions.
The poultry thermal comfort zone, or thermoneutrality, depends on species and age, with younger birds responding better to warmer temperatures. Broiler feed conversion deteriorates when temperatures are outside the recommended comfort zone. Bird responses are predominantly affected by the dry-bulb temperature of the air space.
Broilers produce heat that must be lost to the environment to maintain constant body temperatures. Broiler heat loss is comprised of two components; latent heat loss and sensible heat. Latent heat loss is usually expressed as the amount of water evaporated from the broiler, referred to as moisture production. Evaporation uses broiler heat to change water state ______ ___ ______ _______ _______ ___ _______ __________ _____ ____ _______.
