Heat stress is a major welfare problem in dairy and beef cattle, causing suffering and production losses that motivate farm investment.
Heat stress in cattle causes genuine suffering — elevated body temperature, panting, reduced appetite, and physiological strain affect animal welfare directly, not merely production metrics. In extreme heat events, cattle can die from heat exhaustion. The economic incentive to provide cooling infrastructure aligns with welfare motivation, making heat stress management an area where farmer interest and animal welfare converge. However, in extensive grazing systems, access to shade and water may be inadequate, and climate change is intensifying heat stress events beyond what traditional management was designed to handle.
