Why are pigs' tails docked?
Besvaret 26. oktober 2026
Pigs' tails are docked to reduce tail biting, where pigs bite each other's tails. Danish rules ban routine tail docking. Piglets may still be docked on day 2 to 4 of life if there is written evidence of tail biting and other measures against it have been tried first. A vet or a trained person may do it without anaesthesia. Even so, about 95 percent of Danish piglets are docked, according to the ministry's background material for a citizens' panel on animal welfare. The EU food safety authority EFSA finds that docking lowers the risk of tail biting but does not remove it, and that the procedure causes pain both during and for some time after. Whether the pain lasts in the long term is unclear. In an inspection campaign by the Danish Veterinary and Food Administration, just over half of the violations were herds unable to document the need to dock.
