Cattle Welfare in Summer: Shade, Water, and Heat Management

Summer heat management for cattle requires proactive provision of shade, cool water, and ventilation to prevent welfare-compromising heat stress as temperatures rise.

Key Facts

Cattle enter heat stress when temperature-humidity index exceeds 72
High-yielding dairy cows have greater heat stress risk due to metabolic heat production
Shade provision reduces core body temperature by up to 2 degrees Celsius
Water intake increases three to four fold during heat stress
UK summer temperatures are increasingly exceeding cattle heat stress thresholds

Welfare Considerations

Cattle experiencing heat stress show panting, reduced activity, and decreased feeding with consequent welfare and production impacts. Severe heat stress causes death in animals unable to thermoregulate. Shade reduces radiant heat load dramatically and is a simple cost-effective welfare intervention. Cool, fresh water available ad libitum is critical; hot or dirty water is avoided by heat-stressed cattle even when thirsty. Welfare-conscious summer management prioritises shade provision, water quality, and where possible cooling through fans and sprinklers.

What You Can Do

Ensure shade is available for all cattle in summer across the full paddock area
Provide cool, fresh water in adequate numbers of troughs for herd size
Advocate for heat stress management requirements in UK dairy welfare codes
Support investment in cooling infrastructure on UK dairy farms
