Sheep Heat Stress and Shade: Welfare in Warm Climates

Overview of heat stress welfare in sheep, particularly in warm and Mediterranean climates.

Key Facts

Wool provides insulation in both cold and hot weather, making sheep heat-tolerant but not immune
High temperatures during shearing windows create welfare risks
Shade provision significantly reduces heat stress in sheep in hot conditions
Water availability during hot weather is critical for sheep welfare
Pregnancy toxaemia risk increases in heat-stressed ewes with energy deficits

Welfare Considerations

Sheep heat stress welfare is less severe than in pigs but remains significant, particularly during shearing transition periods when insulation is abruptly removed. Water access and shade are primary welfare interventions in warm climates. Shearing timing should consider both welfare and practical farm management. Climate change is extending heat stress risk to sheep farming regions historically less affected.

What You Can Do

Ensure adequate shade and water access for sheep during hot weather
Plan shearing timing to minimise heat stress risk during the transition period
