RISK FACTORS FOR EAR NECROSIS AND TAIL LESIONS IN WEANERS

摘要

Ear necrosis (EN) is seen in weaners and older pigs and is usually located around the edge of the ear. Some authors consider EN to be a result of biting by other pigs (1). Others believe it to be caused by infection, possibly as a sequel to a primarytrauma (2). Tail lesions (TL) are generally considered to be a result of abnormal behaviour. The aim of this study was to identify herd factors which are associated with EN and TL in weaners.
