Lung Scanning

Our vets can scan your sheep to search for lesions caused by OPA

Lung Scanning

OPA, also known as Jaagsiekte, is a virus that causes lung tumours. These tumours make breathing difficult, so affected sheep often lag behind when gathered. They also predispose animals to pneumonia and cause poor performance; poor weight gain, poor fertility and poor milk production. It is spread by close contact between sheep. There is no blood test, no treatment and no vaccine so our best tool for this disease is to ultrasound scan lungs looking for the tumours. Depending on your situation, this could be screening purchased tups, scanning ill-thrifty or slow gathered stock or even your whole breeding flock. Infected sheep can then be removed from the flock with some carcase value and before they spread more virus.
