Farmed Cattle Heat Stress and Shade

Cattle experience heat stress at lower temperatures than humans and providing shade is one of the most effective and low-cost welfare interventions.

Key Facts

Cattle begin experiencing heat stress at approximately 22 degrees C at 50% humidity
Heat stress reduces milk production, reproduction, and feed intake in dairy cows
Shade provision reduces core temperature, respiration rate, and stress hormones
Natural tree shade is more effective than artificial shade structures
In outdoor systems, pasture access with shade trees is the welfare gold standard

Welfare Considerations

Cattle on farms without shade access suffer chronic heat stress throughout summer months, with compounding effects on health, reproduction, and welfare. Providing shade through pasture trees or shade structures is a simple, low-cost intervention with large welfare benefits in warm climates.

What You Can Do

Support welfare standards requiring shade provision in outdoor cattle systems
Advocate for tree planting in pastures for both cattle welfare and environmental benefit
Choose dairy products from farms with confirmed pasture access and shade provision
