Porcine reproductive and respiratory syndrome virus (PRRSv) is one of the most costly and difficult to manage diseases within the swine industry. In breeding herds, it causes reproductive losses such as substantially increased incidence of abortions and mummies, and infertility. Downstream, in pigs of all ages, it causes pneumonia with clinical signs such as thumping and coughing, and impacts production by reducing growth and increased mortality. The control, elimination and prevention of PRRS is an integral part of modern swine management, especially in breeding herds.
