Welfare Science

Pig Welfare and Precision Fermentation

Precision fermentation producing animal proteins without keeping animals represents a potentially transformative technology for pig welfare by reducing demand for conventional pork.

Key Facts

Precision fermentation produces functional animal proteins including casein and whey without livestock
Several companies are developing pork protein equivalents through fermentation
Production costs are declining rapidly following the trajectory of earlier biotechnology
Consumer acceptance remains a challenge particularly in markets with strong meat culture
If adopted at scale precision fermentation could significantly reduce pig production volume

Welfare Considerations

Precision fermentation represents a technological path to meeting protein demand without the welfare costs of large-scale pig farming. As production costs decline and consumer acceptance increases, precision fermentation could progressively reduce the scale of pig welfare problems globally.
