Heat stress in feedlot cattle causes significant welfare harm and production losses, with practical management interventions available that are underutilized in many commercial operations.
Feedlot cattle heat stress causes substantial suffering including panting, bunching in shade, reduced feeding activity, and in severe cases collapse and death. The welfare impact extends beyond visible distress — chronic moderate heat stress impairs immune function, increases acidosis risk, and reduces the ability to recover from disease. Despite the availability of effective interventions including shade structures, sprinklers, and modified feeding schedules, provision varies enormously between operations. As climate warming increases heat stress frequency and severity, the welfare gap between well-managed and poorly managed feedlots will widen without regulatory incentive for improvement.
