Heat stress in feedlot cattle is a significant and growing welfare problem as temperatures rise. Effective management tools exist but require investment and policy support to deploy widely.
Feedlot heat stress is both a current welfare problem and a growing one as climate change intensifies. Cattle in feedlots without shade or cooling access experience thermal distress that begins at relatively moderate temperatures for high-producing beef breeds. The welfare harm accumulates through altered physiology, immune suppression, and behavioral restriction as animals seek to minimize heat gain. Death in extreme heat events represents the acute end of a spectrum of ongoing chronic welfare compromise. The management tools are available: shade structures, sprinklers, misters, and water distribution management all reduce thermal stress. The barrier is primarily cost and the absence of regulatory requirements that mandate shade provision as a basic welfare requirement.
