Pig Genetic Welfare and Breed Diversity

Genetic diversity in commercial pig populations has declined substantially, with welfare implications including increased disease susceptibility and loss of stress-coping variation.

Key Facts

Large White and Landrace genetics dominate global commercial pig production
Genetic selection has prioritised lean meat yield, growth and litter size over welfare traits
Breed diversity provides resilience against disease and local adaptation for welfare-relevant traits
Indigenous pig breeds often show better environmental adaptability and lower disease susceptibility
Rare breed conservation programmes maintain genetic diversity with welfare and cultural benefits

Welfare Considerations

Narrow genetic diversity in commercial pigs creates vulnerability to disease outbreaks and limits welfare trait variation. Supporting genetic diversity is both a welfare and biosecurity investment.

What You Can Do

Support rare pig breed conservation organisations including the Rare Breeds Survival Trust
Choose pork from heritage or rare breed pigs occasionally to support genetic diversity
Advocate for welfare trait inclusion in commercial pig breeding programme selection indices
