Farm Animal Welfare: Genetic Diversity and Heritage Breeds

The loss of genetic diversity in commercial livestock breeds reduces disease resilience and constrains welfare options, while heritage breed conservation supports future adaptability.

Key Facts

Commercial livestock production is dominated by a handful of highly selected breeds
Global livestock biodiversity has declined substantially as commercial breeds displace local varieties
Rare breeds often have better disease resistance and adaptation to local conditions
The Rare Breeds Survival Trust monitors population levels of UK heritage breeds
Some heritage breeds have better welfare outcomes than commercial strains under extensive conditions

Welfare Considerations

Genetic diversity in livestock has direct welfare implications - homogeneous populations are more vulnerable to disease outbreaks and have less adaptability to changing conditions including climate. Heritage breeds adapted to local environments may have better welfare outcomes in appropriate management systems than commercial breeds that perform optimally only under intensive conditions. Diversity conservation is both a welfare and a food security issue.
