Pigs have demonstrated sophisticated empathic responses in scientific studies. This evidence challenges the assumption that farm animals lack the emotional complexity relevant to welfare considerations.
The scientific evidence for pig cognition and empathy is substantial and growing. Pigs living in impoverished environments — including gestation crates, slatted concrete floors, and barren pens — are denied the opportunity to exercise complex social and cognitive abilities. This constitutes a serious welfare problem that goes beyond physical pain to encompass frustration, boredom, and psychological suffering. Housing systems that accommodate pig social complexity produce measurably better welfare outcomes.
