Welfare Science

Precision Fermentation Animal Welfare

Precision fermentation producing animal proteins without animals represents a potentially transformative technology for reducing farmed animal numbers and associated welfare costs.

Key Facts

Precision fermentation uses microorganisms to produce exact replicas of animal proteins
Whey protein, casein, and egg white are among the first commercial precision fermentation products
If successful at scale, precision fermentation could eliminate need for farmed dairy and egg animals
Current production costs remain higher than conventional animal agriculture equivalents
Consumer acceptance is growing as precision fermentation products reach commercial markets

Welfare Considerations

Precision fermentation represents one of the most promising long-term pathways to dramatically reducing farmed animal numbers and associated welfare harms. Supporting technology development and consumer adoption of precision fermentation products is a welfare intervention with potentially enormous scale benefits.
