Invitation to Sheep Health meeting

Tackling one of the most significant diseases facing the sheep industry.

Moredun are running a sheep health meeting at Peebles Hydro, Peebles, EH45 8LX on Thursday 28th November from 7-10pm, kindly sponsored by Glenrath Farms.



This is an open meeting to which everyone is welcome and is free of charge, where Dr Chris Cousens from Moredun will share her latest research results on the use of ultrasound scanning to control OPA (Jaagsiekte) in sheep flocks. OPA is one of the most important diseases facing the sheep industry. It is an infectious lung cancer caused by a virus known as Jaagsiekte sheep retrovirus (JSRV). Typical symptoms of OPA are difficulty in breathing, often with marked weight loss and over-production of fluid in the lungs which sometimes is apparent by a frothy, runny discharge from the nose. There is currently no treatment and as clinical signs can take years to develop, diagnosis is difficult and infected sheep may be spreading virus through a flock for many months or years before a diagnosis is made.

Recently Moredun has been investigating detection of OPA tumours by ultrasound scanning and has been working with flocks throughout Scotland for the past three years using a scan and cull policy. The results of this work will be discussed at the meeting, along with showing Moredun’s new film on how this form of OPA control is working well for one flock.

A parasite of high economic importance to sheep farmers, liver fluke, will be another topic under discussion at this event. Control of fluke in the light of a very wet late summer and autumn, along with increasing reports of resistance  to some of the treatments use to control infection will be discussed, focusing on up-to-date good practice advice, and featuring Moredun’s entertaining and informative animated film “Fight the Fluke”.

The Moredun Foundation is a registered charity that promotes animal health and welfare through research and education. The Foundation, which governs the work of the Moredun Research Institute, is dedicated to a simple belief that the greatest benefit to animal welfare is the cure or prevention of disease.

Moredun Research Institute conducts internationally recognised research on the infectious diseases of livestock, caused by important viruses, bacteria and parasites. It employs 170 scientists, vets and support staff who continue to help find solutions for major challenges to modern farming such as the consequences of a changing climate; ensuring safe and sustainable food and water supplies conserving biodiversity and finding solutions to infectious disease. Today, many of the veterinary medicines and vaccines that are routinely used on farm have either been researched, developed or tested at Moredun.
