Iceburg Diseases in Sheep – Maedi Visna (MV) and Caseous Lymphadenitis (CLA)

Maedi Visna (MV) and CLA are two of the “Iceberg” diseases of sheep. While the clinical presentation of these production-limiting diseases is mild, they often cause inefficiency through subclinical disease. The extent of the problem within a flock can be underestimated because visibly diseased sheep are usually just the tip of the problem. In this module you will learn about clinical signs and treatment, prevention and control of the disease.
