Precision fermentation offers a pathway to animal products produced without farm animals, with significant implications for welfare at scale.
Precision fermentation represents a potential paradigm shift for animal welfare by decoupling animal product components from animal farming entirely. If commercially successful at scale, precision fermentation dairy, egg, and potentially meat proteins could provide consumers with familiar products while eliminating the welfare costs of the farming systems that traditionally produce them. The welfare implications are transformative at scale - fermented dairy could eliminate the welfare costs affecting billions of dairy cows and their calves if it achieves mainstream market penetration.
