PRRSV infection in both breeding and finishing herds has a significant negative financial impact on the herd.
PRRSV and other pathogens
PRRSV interacts with other pathogens to cause severe respiratory symptoms in finishing pigs.
Vaccination against PRRS
In 1987 Porcine Reproductive and Respiratory Syndrome (PRRS) was first observed in pig herds in the United States. In 1990 the first case of PRRS was reported in Europe. By the early 1990s PRRS become pandemic.
To this day the disease causes significant losses in the pig industry due to reproductive disorders and growth retardation.
Economic impact of PRRSV infection in a pig herd
Losses from PRRSV infection is due to decreased farrowing rates, increased pre-weaning mortalities and increased respiratory disease in finishing pigs.
PRRS control in different pig herds
Vaccination, partial or total depopulation strategies and test or removal or acclimatisation of new animals are all necessary for effective PRRS control in breeding as well as finishing pig herds.
