Porcine reproductive and respiratory syndrome (PRRS) is devastating. First detected in the United States in 1987, it now costs North American farmers more than $600 million annually.
Pigs that contract the disease exhibit an inability to conceive, increased late-term abortions, premature farrowing, stillborn pigs, and weak piglets that often die before weaning or show slow growth and development. The airborne virus can be passed from sow to pig.
There is no cure. Vaccination, especially modified live vaccines, can control clinical signs and reduce virus shedding. Broad-spectrum antibiotics and anti-inflammatories can help control secondary infections and symptoms.
For some farmers, the only way to rid their operation of the virus is to cull the herd, then wait several months to restock. Variants differ from region to region. All sizes of hog farms are affected.
