How advances in farm animal sentience research are reshaping understanding of what cattle, pigs, and chickens experience.
Farm animal sentience research is expanding the moral circle in ways with direct implications for welfare policy and practice. Research demonstrating that pigs show empathy, chickens make referential calls about food quality, and cattle form complex social bonds challenges the historically convenient assumption that these species have limited inner lives. This science provides the evidentiary foundation for stronger welfare standards and is increasingly cited in legislative debates. The growing consensus that farm animals have rich emotional and cognitive lives creates ethical pressure for production systems that respect these capacities.
