Pig Welfare and Genetic Diversity Advanced

Genetic diversity in pig populations supports welfare through resilience to disease, reduced inbreeding depression, and adaptation to changing conditions.

Key Facts

Rare breed pig populations are maintained in conservation herds as genetic reserves
Inbreeding depression causes reduced immune function, fertility, and welfare in highly selected lines
Native breeds often show superior welfare in outdoor systems where their adaptations are matched
Gene bank initiatives preserve genetic diversity for future welfare and production challenges
Genetic diversity within commercial breeds is maintained through rotational crossing programmes

Welfare Considerations

Genetic diversity is a foundation of welfare resilience - diverse populations can adapt to disease challenges, management changes, and environmental pressures that inbred populations cannot. Maintaining diversity in pig genetics is therefore both a welfare and food security priority.

What You Can Do

Support rare breed pig conservation through Rare Breeds Survival Trust
Advocate for genetic diversity metrics as part of pig welfare certification
Engage with breeding companies about genetic diversity maintenance in commercial pig genetics
