Summary and Implications
Economic impacts based on PRRS associated losses as reported in a previous study were modeled with varying grain prices. Sensitivity tables show that as grain (feed) prices rise, the economic impact of disease events increases. As corn prices rise from $2.25/bu up to $5.00/bu, there is a $92.6 million increase in the cost of PRRS to US pork producers. Every $0.50/bu increase in corn price costs the pork industry $18.52 million in PRRS associated losses. In the PRRS-affected farm, for every $0.50/bu increase, the cost per litter increases $0.886, the cost per nursery pig increases $0.072/hd and the cost per finisher pig increases $0.405/hd. With corn at $2.50 to $5.00/bu the national impact is estimated at $594.19 to $686.77 million annually, or $5.94 to $6.87/hd marketed in the US. As feed prices rise, the value of improved health care also rises. As costs rise, it is imperative to continue efforts on disease control and prevention.
