The following two examples illustrate the economic impact of an acute PRRS outbreak and the impact on a farm endemically infected with PRRSV.
A large pig unit, rearing almost 400,000 pigs a year, experienced a PRRS outbreak followed by PRDC syndrome. The outbreak created serious damage in all the existing pig categories.
The economic effect of this PRRS - PRDC outbreak was calculated as loss of 17.02 US$ / mating sow / year (Gntanu et al. 2002).
On a farm endemically infected with PRRSV, the clinical effect of post-weaning PRRS was:
(Dee S. et al. 1997)
All of the above studies show that infection with PRRSV can have a significant financial impact on both the sow and the finishing herd.
