Needle teeth clipping in newborn piglets is routinely performed to prevent sow teat damage, but evidence supports more targeted approaches that reduce welfare harm.
Needle teeth procedures on neonatal piglets represent a painful intervention performed at the most vulnerable period of the piglet's life. Clipping with wire cutters creates sharp edges and infection risk. Selective approaches that only treat piglets causing actual teat damage reduce the number of animals subjected to the procedure. Grinding causes less acute trauma than cutting and produces smoother tooth surfaces less likely to cause secondary wounds.
