Pigs are increasingly used in biomedical research due to physiological similarities to humans, requiring rigorous welfare standards given their cognitive complexity.
Pig use in biomedical research carries significant welfare implications given documented cognitive complexity, social needs, and emotional capacities. Research pigs housed in barren, socially isolated conditions experience welfare harms that compromise both animal wellbeing and research reproducibility. Enriched group housing, refined handling, and replacement with computational models or in vitro systems where validated are ethical requirements.
