Pigs rank among the most cognitively sophisticated farm animals, capable of complex problem-solving, emotional learning, and social understanding that intensive farming systems largely ignore.
The cognitive complexity of pigs means that barren intensive environments cause not just physical frustration but cognitive deprivation. Pigs denied rooting, exploration, social complexity, and learning opportunities develop stereotypies — repetitive behaviours indicating chronic psychological frustration. The welfare implications of housing an animal with canine-level intelligence in an barren concrete pen are profound and largely unacknowledged by mainstream production systems.
