Pigs are among the most cognitively sophisticated farmed animals, with research demonstrating video game playing, mirror self-recognition in some studies, and complex social learning — evidence that raises the moral stakes of standard farming practices.
Pig cognition research creates a moral obligation to provide stimulating, socially complex environments that engage these substantial mental capabilities. The standard barren pen with slatted flooring and low-stimulation environment is profoundly mismatched with pig cognitive needs. The practical translation of cognitive evidence into welfare standards — enrichment requirements, social grouping, cognitive challenge — is an active area of farm animal welfare science with direct policy implications.
