Tail Posture as an Indicator of Tail Biting in Undocked Finishing Pigs.

ABSTRACT: Tail posture (i.e., hanging or curled) has been suggested to be an indicator of tail biting, and hanging tails predisposed to damage. The aim of this study was to investigate if tail posture was feasible as a tail damage indicator in a commercial setting. The study was carried out on one batch of 459 undocked finishing pigs (30⁻120 kg in weight). Weekly scoring of tail posture was combined with the scoring of tail lesions. Tail posture was observed at feeding to facilitate the usage of the method in commercial settings. A curly tail was observed in 94% of the observations. Pigs with tails scored with "wound" were 4.15 (p < 0.0001) times more likely to have hanging tails, and pigs scored with "inflamed wounds" were 14.24 (p < 0.0001) times more likely to have hanging tails, compared to pigs
