Heat stress in feedlot cattle causes significant suffering, reduced welfare, and substantial economic loss, yet effective mitigation measures remain underutilized across the industry.
Feedlot cattle in hot climates endure extended periods of heat stress that cause physiological strain, discomfort, and reduced immune function. High-humidity conditions are particularly dangerous and can cause mortality during extreme heat events. The welfare case for mandatory shade and sprinkler provision in feedlots is strong and supported by economics as well as ethics. As temperatures increase with climate change, heat stress mitigation becomes an increasingly urgent welfare priority.
