Tail biting is one of the most significant welfare problems in intensive pig farming and has systemic causes that require systemic solutions.
Tail biting is a symptom of poor welfare rather than a problem in itself, and tail docking — cutting off piglets' tails to reduce injury from biting — treats the symptom rather than the cause. The root causes are rooted in the barren, overcrowded conditions of intensive pig farming: frustrated exploration motivation redirected onto pen-mates. Sweden's success in eliminating tail docking through better management demonstrates that the industry has the knowledge and tools to solve this problem — what is lacking is the regulatory pressure and economic incentive to implement them.
