Pig Welfare and Precision Fermentation

Precision fermentation technology is producing animal proteins without animal farming, with potentially transformative implications for pig welfare.

Key Facts

Precision fermentation uses microorganisms to produce proteins identical to those from animal sources
Commercial production of fermented whey, casein, and egg white proteins is underway
If successful at scale, precision fermentation could eliminate most industrial pig farming
Regulatory approval for precision fermented ingredients is progressing in multiple jurisdictions
Consumer acceptance will be a critical factor in determining the welfare impact of precision fermentation

Welfare Considerations

Precision fermentation represents one of the most potentially transformative technologies for farm animal welfare. Products that satisfy consumer needs for protein without animal farming could fundamentally change the demand landscape for intensive pig production.
