Access to shade and water during hot weather is a fundamental welfare requirement for all farmed livestock that reduces heat stress, improves production outcomes, and prevents suffering.
Shade and water access during hot weather is a welfare minimum that is frequently absent in extensive livestock systems. Animals without shade during heat waves experience thermal distress that progresses from behavioral changes to physiological stress responses and in extreme cases to death. The welfare obligation to provide shade and adequate water access is both ethically grounded and practically important — heat-stressed animals grow more slowly, produce less milk, and have impaired reproduction, aligning welfare and production interests. Climate change is making heat stress management an increasingly critical welfare and production challenge across farming regions.
