Pityriasis Rosea

(475) This is a sporadic condition seen in young pigs from 3 to 16 weeks of age. It is characterised by large coalescing ringworm like lesions that often start on the abdomen and spread up behind the back legs and ultimately in severe cases involve the whole of the body. (Fig.10-20). It is believed to have a hereditary background particular in the Landrace breed. The lesions are characteristic and the condition naturally resolves itself over 6 to 8 weeks. No treatment is required. It is of no consequence apart from being unsightly but may cause customer reactions if you are selling 25kg weaners to finishers.


Note the raised ringworm like lesions.
