Sheep Medicine 5.jpg


A farmer complains of severe skin lesions on the muzzle and lips of approximately 25% of 120 6-month-old lambs, 10–14 days after movement on to pastures containing large numbers of thistles (site of special scientific interest). The skin is oedematous with serous exudation and superficial pus accumulation, has become desiccated, forming hard scabs separated by deep fissures. Careful removal of a scab reveals a deep bed of exuberant granulation tissue. Scab material narrowing the nostrils causes dyspnoea with stertor and abdominal breathing in some lambs.
