Pig welfare challenges vary significantly between tropical, temperate, and cold climate regions, with heat stress, disease pressure, and housing requirements differing by climate zone.
Key Facts
Heat stress is a major welfare concern for pigs in tropical and subtropical production systems
Pigs have no sweat glands and rely on wallowing, shade, and evaporative cooling
Cold climate pig welfare requires adequate insulation and draught exclusion in housing
Disease pressure from parasites and pathogens varies significantly by climate zone
Outdoor pig systems face different welfare challenges in wet, dry, hot, and cold climates
Welfare Considerations
Pig welfare globally requires climate-adapted management and housing that addresses the specific thermal and environmental challenges of each region. Welfare standards developed in temperate northern Europe may not be directly applicable in tropical producing countries without climate adaptation.
What You Can Do
Support international pig welfare research that addresses climate zone differences
Advocate for climate-adapted welfare standards in countries with different production environments
Engage with global pig welfare organisations addressing challenges across different climates
