Porcine Reproductive and Respiratory Syndrome Assessment

Colin Johnson, Extension Program Specialist, Animal Science


Porcine Reproductive and Respiratory Syndrome (PRRS) is one of the most devastating diseases in the swine industry.  Much is unknown about its aggregate cost and how it can be altered.


To provide an assessment of the production and financial losses associated with PRRS in the USA swine industry and increase awareness of the potential impacts of PRRS virus while gaining support for increased control and eradication efforts.


Through producer meetings and one-on-one consultations, production records were obtained from farmers and their veterinarians revealing losses associated with PRRS outbreaks.  Economic values were placed on these losses and aggregated to the industry.  An extensive Delphi survey of swine veterinarians was conducted to further validate findings and achieve cost estimates beyond the production losses.  Results were released back to the industry through multiple academic and media channels.  Producer meetings were held and thirteen farms received an economic assessment of their operations.


Based on 2003 figures, the assessment revealed that production losses associated with PRRS costs the USA swine industry an estimated $560.32 million annually.  A calculation model now allows farms to quantify the impact of PRRS on their own farms.  Swine producers across the country believe this challenging disease is one worthy of control and eradication efforts.
