Thermal management to avoid heat stress during transport

The factsheet describes good practices for preventing and mitigating heat stress in poultry transported to slaughter, particularly end-of-lay birds, i.e., laying hens and broiler breeders, that often face long journeys and extended water deprivation. It recommends assessing weather conditions before transport, monitoring temperature and humidity, and observing birds for signs of heat stress such as panting and reduced vocali-sation. Planning measures include coordinating catching, transport and slaughter schedules to minimise waiting times and reducing stocking density by placing fewer birds per crate. Vehicle adaptations such as ad-justable side curtains, liftable roofs, ventilation openings, and mechanical ventilation systems can improve airflow. When parked, additional cooling can be provided through shade, fans, sprinkler systems, and roof cooling. Driver training and emergency contingency plans are also essential.
