Pig Genetic Diversity Welfare | Animal Welfare Hub

Genetic diversity in commercial pig populations affects disease resilience and welfare, with intense selection creating both benefits and risks.

Key Facts

Commercial pig populations are dominated by three main breed lines with limited genetic diversity
High inbreeding coefficients increase susceptibility to diseases where heterozygosity provides resistance
Conservation of rare pig breeds maintains genetic diversity that could be valuable for future breeding
Genomic selection allows faster introgression of diversity from conservation breeds when needed
Genetic erosion in commercial lines risks creating populations vulnerable to novel pathogen emergence

Welfare Considerations

Pigs with low genetic diversity face elevated disease susceptibility that creates welfare risks when novel pathogens emerge. Maintaining diversity through conservation breeding programs protects future populations' health and welfare.

What You Can Do

Support rare breed conservation programs for Berkshire, Oxford Sandy and Black, and other heritage pig breeds
Advocate for genetic diversity monitoring in commercial pig breeding programs
Choose pork from farms using breeds with documented genetic health management
