Maedi-Visna (MV) also known as Ovine Progressive Pneumonia (OPP), is one of the major production limiting diseases facing the Canadian sheep industry. Because of the long incubation period of the virus, lambs infected early in life remain in the flock until clinical signs develop, most commonly after 4 years of age . OPP is the “silent thief”.
The only way to manage the risk is to source replacement breeding stock from OPP negative flocks. Being OPP negative means that you deliberately are testing your flock for the disease.
The only way to be sure is to test.
