In this article we will review the main agents involved in the so-called Porcine Respiratory Disease Complex (PRDC), how they affect the main productive parameters in pig farms as well as the increase in production costs and the economic losses that they produce.

The respiratory disease complex is present worldwide in all countries and areas where intensive modern swine production was developped. PRDC has a strong negative health, welfare and economic consequences in modern swine farms.

Swine influenza is endemic on most European pig farms, and on many of them it goes undiagnosed. The virus is shed for only a few days, so by the time you are looking at coughing pigs, PCR is often already negative. Regaining control means sampling the right age groups, identifying the strains circulating on your own farm, and vaccinating consistently across the herd.
