Cattle transported in warm conditions face severe heat stress risk. Understanding the welfare implications and management strategies reduces suffering during this common agricultural activity.
Cattle transport during warm weather creates compound welfare risks through the combination of journey-related stress, restricted movement, and thermal challenge. The interplay between high metabolic heat generation from stress, solar radiation loading, poor vehicle ventilation, and high ambient temperatures can quickly escalate from discomfort to life-threatening heat stroke in susceptible animals. Welfare-appropriate transport management in warm conditions requires scheduling journeys during cooler periods, ensuring vehicle ventilation is adequate and functioning, providing journey breaks with water access, and avoiding overcrowding that compounds thermal load. Refusing to transport cattle in conditions where heat stress risk cannot be adequately managed is a welfare-appropriate decision that operators should feel empowered to make.
