Aural haematoma.
A haematoma is a pocket of blood that forms beneath the skin or in muscle tissue and is associated with a ruptured blood vessel. Haematomas of the ear in pigs cause discomfort. If left untreated, a haematoma will usually resolve by itself; however, this may take several time. Ear haematomas result from various traumas. Pigs may develop these haematomas from shaking their heads, from injuries caused by ear biting or by catching the pigs from the ears.
