摘要: Tail posture (i.e., hanging or curled) has been suggested to be an indicator of tail biting, and tails predisposed damage. The aim this study was investigate if feasible as a damage in commercial setting. carried out on one batch 459 undocked finishing pigs (30–120 kg weight). Weekly scoring combined with the lesions. observed at feeding facilitate usage method settings. A curly 94% observations. Pigs scored “wound” were 4.15 (p < 0.0001) times more likely have tails, “inflamed wounds” 14.24 compared nondamaged tails. correctly classified wound” 67.5% time, 55.2% sensitivity 79.7% specificity, respectively. observing position seems useful complement normal inspection for detecting biting before wounds are visible caretaker.
