mystery pig disease

A swine livestock disease, first reported in Germany and the UK, that causes devastating reproductive losses and nursery-grower pig respiratory disease, and which has been linked to the PRRS virus. 

Clinical findings
Animals go “off feed” for about a week, showing signs of pneumonia. Within 1–2 weeks, sows at 105–112 days gestation abort—abortions do not occur at earlier stages of gestation—the period of which lasts about 2 weeks. Some litters have piglets that are weak at birth, which often die or become infected and then die. Preweaning mortality may reach 40%.
