Tail docking in commercial pig farming addresses tail biting caused by barren environments and overcrowding, but treats symptoms rather than causes.
Tail docking causes acute pain and creates a permanent wound vulnerable to infection. The practice exists to treat a symptom of barren, overcrowded conditions rather than addressing root causes. Providing adequate enrichment and space would eliminate the need for docking. The persistence of routine docking reflects cost prioritization over animal welfare in most commercial pig systems.
