Pig Teeth Clipping Welfare Evidence

Routine teeth clipping in newborn piglets is a painful procedure whose welfare justification is increasingly questioned by science.

Key Facts

Piglets are born with eight sharp needle teeth that can injure the sow's teats during nursing
Routine clipping of these teeth has been standard practice but welfare evidence challenges this
Scientific reviews find limited evidence that clipping prevents teat injury under normal litter sizes
Clipping causes acute pain and potential infection in neonatal piglets
EU law and UK regulations permit clipping only when there is evidence of injury, not as routine

Welfare Considerations

Routine teeth clipping imposes certain acute pain on neonatal piglets for uncertain and often undemonstrated benefit. The welfare evidence increasingly supports restriction to cases where teat injury is documented rather than routine prophylactic clipping.

What You Can Do

Advocate for enforcement of regulations restricting teeth clipping to non-routine use only
Support research into alternative management of needle teeth and teat injury prevention
Choose pork from farms that document teeth clipping policy and restrict to evidence-based use
