Pig Welfare and Genetic Diversity Preservation

Genetic diversity in pig populations supports welfare by reducing disease susceptibility and inbreeding-related health problems.

Key Facts

Modern commercial pig populations are derived from just a handful of breeds
High inbreeding coefficients increase incidence of immunodeficiency and developmental defects
Native and heritage breeds often have better welfare outcomes but lower production efficiency
Genomic selection can improve welfare traits while maintaining genetic diversity
Cryo-preservation programs protect genetic diversity for future breeding options

Welfare Considerations

Genetic diversity is a foundation of pig health and welfare. Breeding programs that prioritise welfare traits alongside production must also preserve diversity to avoid long-term health decline.

What You Can Do

Support heritage breed conservation programs
Advocate for genetic diversity metrics in pig breeding programs
Choose pork from breeds with documented welfare advantages
