Pig Teeth Clipping and Grinding: Welfare Implications

Neonatal piglet teeth clipping or grinding is performed to prevent sow teat injury and sibling fighting. The welfare implications and alternatives are important for producers to understand.

Key Facts

Piglets are born with eight needle teeth (canine and lateral incisor teeth)
Routine clipping or grinding reduces injury to sow teats and sibling skin
EU regulations require clipping only when justified, not routinely
Grinding is less welfare-compromising than clipping when performed correctly
Poorly performed clipping fractures teeth, creating sharp edges and infection risk
Adequate litter size management and nutrition reduce the need for intervention

Welfare Considerations

Tooth clipping without anaesthesia causes acute pain in neonatal piglets. Poorly performed clipping leaves fractured tooth remnants causing chronic infection and pain. The welfare case for routine tooth clipping is weak when litter management and sow nutrition are optimised. Grinding produces smoother surfaces with less acute trauma. EU regulations requiring justification for tooth intervention reflect the consensus that routine clipping is unnecessary when good husbandry is practised.

What You Can Do

Support pig producers avoiding routine tooth clipping through litter size management
Advocate for tooth clipping to be prohibited without veterinary justification in pig welfare legislation
Choose pork certified to standards requiring evidence-based rather than routine tooth intervention
