Effects of PRRS Challenge on Pig Growth and Metabolic Pathways

The goal was to characterize changes in blood metabolic and immunological parameters of pigs infected with PRRSV. Seventy-six gilts were selected and randomly assigned to one of four pens in a commercial finishing unit.

Key Points:

  • Within a population, pigs handle a porcine reproductive and respiratory syndrome virus (PRRSV) challenge differently.
  • Even though all pigs were infected with PRRSV, the low-growth rate pigs had a 26 percent reduction in average daily gain versus the high-growth pigs.
