Preputial Ulcers

(477) These occur as areas of wet eczema around the skin on the end of the prepuce.

Clinical signs

The ventral part of the prepuce near the opening is swollen, oedematous, red and painful. It is only shown in outdoor boars and is sporadic. The lesions are usually quite obvious and may become extensive.


The cause of this condition is unknown but the possibility of a virus infection cannot be ruled out. Frost bite may be another cause. Secondary bacterial infection develops.


  • Isolate the boar until the lesions have healed.
  • Apply an antiseptic antihistamine cream.
  • Spray with antibiotic.
  • If the prepuce is badly infected inject the pig with long-acting amoxycillin.
  • Consider culling affected animals.
