What’s Wrong With My Pigs? Ear Necrosis

17 June 2016


Porcine ear necrosis syndrome (PENS) in pigs has been reported as an increasing health problem in many countries with intensive pig farming. PENS exhibits as tissue damage to the tips of ears. Researchers have found it occasionally in pigs at three weeks, but it is most common in pigs 5 to 16 weeks of age

Sometimes only a few pigs are affected and the lesions are barely noticeable, but there are outbreaks where all the pigs are affected and many with extensive lesions.

non-infectious agents.
