Where: skin and subcutaneous tissue
Caused by: Other
The lesion seen in this 60-kg pig is a bilateral necrosis of the pinnae.
The cause of this lesion has not been determined conclusively; this case may suggest fights between several animals and subsequent contamination of the injured tissues.
Stressors (inadequate densities, mixing pigs by age and/or litter, drinkers that don't work properly, ventilation, etc.) and feed quality may be risk factors for this type of injuries.
