Decades of research have established pigs as among the most emotionally and cognitively sophisticated farm animals, making the conditions of intensive pig farming a profound ethical challenge.
The cognitive and emotional sophistication of pigs makes the reality of conventional pig farming particularly troubling from a welfare perspective. Gestation crates that prevent movement, early maternal separation, barren environments, and tail docking without analgesia are standard practices that cause significant suffering in animals capable of rich emotional experience. Evidence-based welfare improvements — enrichment, space, social housing — are feasible and increasingly required in some jurisdictions.
