摘要

A recent NSA webinar, run in conjunction with Moredun Institute and SRUC, highlighted the need to focus on 'iceberg'diseases to ensure improved sheep productivity and welfare (more on page 5).Iceberg diseases are five infectious diseases of sheep - border disease (BD), caseous lymphadenitis (CLA), Maedi Visna (MV), ovine paratuberculosis or ovine Johne's disease (OJD) and ovine pulmonary adenomatosis (OPA). They have been identified by the sheep industry as important, but farmer awareness is low with a recent survey suggesting less than 5% of flocks are routinely screening for them.
