Neonatal piglets undergo painful routine procedures without adequate analgesia in most commercial systems, but evidence-based protocols for pain management are available and increasingly required.
Neonatal piglet pain management reflects a moral inconsistency: society has largely accepted that animal pain matters, yet the routine procedures performed on commercial piglets are conducted without the pain relief that would be mandatory in any other veterinary context. The regulatory gap persists because of cost arguments and the assumption that neonatal animals feel less pain — an assumption contradicted by neuroscience. Neonatal animals are not less sensitive to pain; they may be more sensitive due to immature inhibitory pain pathways. Practical pain management for commercial piglet procedures is achievable: local anesthetic injection before castration is feasible even at high throughput, and NSAID administration reduces post-procedural pain. The EU regulatory timeline for mandatory analgesia is moving — market pressure from retailers and welfare certification standards is accelerating this.
