Farmed Pig Genetic Welfare Diversity

The importance of genetic diversity in pig populations for resilience, disease resistance, and long-term welfare.

Key Facts

Modern pig production relies on a small number of commercial breeds and genetic lines
Genetic concentration increases vulnerability to novel diseases as seen with ASF and PEDv
Native and heritage breeds often carry welfare-relevant traits that have been selected out in commercial lines
Conservation of rare breed genetics provides insurance against future welfare challenges
Gene banks preserve genetic diversity for future selection when needs change

Welfare Considerations

Genetic diversity in pig populations is a welfare issue as well as a biosecurity concern. Narrow genetic bases can result in diseases sweeping through populations and cause welfare crises affecting millions of animals. Maintaining diversity is a long-term welfare strategy.

What You Can Do

Support rare breed pig conservation programs and organizations
Choose pork from heritage breed producers to support genetic diversity
Advocate for gene bank investment as part of agricultural biosecurity planning
