Routine tail docking in pigs is performed to prevent tail biting but represents a welfare compromise that alternatives can reduce or eliminate when fundamental management causes are addressed.
Tail docking welfare presents a genuine dilemma where one welfare harm (docking pain) is performed to prevent a potentially greater welfare harm (tail biting injury and death). The welfare resolution lies in addressing the root causes of tail biting rather than accepting this trade-off as inevitable. Evidence from intact-tail production programs in several European countries demonstrates that tail biting can be managed to acceptable levels through enrichment provision, appropriate stocking density, good health management, and rapid response to early tail biting before it spreads. The EU policy ban on routine docking reflects this evidence, though enforcement remains inadequate.
