Despite antibiotic and supportive therapy the prognosis is grave, and gangrenous udder tissue eventually sloughs leaving a large granulating surface with superficial bacterial infection. The granulation tissue continues to proliferate over the coming months (up to 10–20 cm diameter).

The infected granulation tissue and resultant drainage lymph node enlargement would result in carcass condemnation (and raise genuine welfare concerns). The fleece is very poor because growth has occurred during this period of illness and debility.<br>

The ewe should be euthanased for welfare reasons at first presentation.

Control measures include ensuring ewes are well fed. Concentrates should be supplied to ewes and lambs when pasture is poor. No ewe should be expected to rear triplets. Teat lesions should be identified and treated with topical antibiotics.
