Dealing with maedi visna in UK sheep flocks

Ogden, Nicky; Davies, Peers; Lovatt, Fiona

Abstract

Background: Maedi visna (MV) is considered to be one of the ‘iceberg diseases’ of sheep; a group of infectious, production-limiting diseases which are endemic to the UK. Characterised by slow, progressive onset, these diseases lie undetected and can have a large impact on flock efficiency. This group of diseases also includes border disease, caseous lymphadenitis, ovine Johne’s disease and ovine pulmonary adenocarcinoma. The prevalence and effects of these diseases within different UK flock types remains unknown. Aim of the article: To highlight the increasing importance of MV within the national flock. Here, we discuss the production effects, diagnosis and control options for MV.
