The development and consequences of ear necrosis in a weaner herd and two growing-finishing herds
In Danish herds, ear necrosis (EN) in weaners and older pigs is mainly located along the ventral edge of the ear. Biting by other pigs and infections (possibly as a sequel to trauma) have been suggested as causes of EN (1, 2).
The aim of this investigation was to explore 1) the development and healing of EN, 2) factors within the herd associated with EN and 3) the effect of EN on the health and growth of the pigs.
