Transporting farm animals in extreme heat or cold causes preventable suffering and high mortality rates.
Farm animal transport in extreme temperatures causes acute suffering and death. Pigs are particularly vulnerable to heat stress because they cannot sweat, and transport vehicles create conditions where body heat accumulates rapidly. Thermal stress causes hyperthermia, organ failure, and death — often slowly. Simple measures — transporting at night, providing water, reducing stocking density, and shade — dramatically reduce heat-related transport mortality. Regulatory temperature limits with genuine enforcement are essential.
