Unexplained weight loss in sheep and goats. A guide to differential diagnosis, therapy, and management

A review of the likely causes of unexplained weight loss in sheep and goats has been presented, with particular emphasis on diagnosis. Through the use of careful clinical examination and knowledge of the likely causes of progressive weight loss, a definitive diagnosis can often be made, although this is not always possible, even with rigorous investigation (Fig. 1). In most cases, establishing a definitive diagnosis will allow the practitioner to institute appropriate therapeutic measures, correct deficient management procedures, or institute suitable prevention and control programs to reduce ongoing or future losses to the client.
