Porcine Respiratory Disease Complex (PRDC)

The term ‘Porcine Respiratory Disease Complex’ (PRDC) has been used to describe the complex characterised by respiratory symptoms and poor growth in ‘finishing’ pigs.

PRDC has a multifactorial etiology involving Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), Swine Influenza Virus (SIV), Porcine Circovirus (PCV) and a variety of bacteria.

Vaccination plays an important role in the control of PRDC, though its success depends on the immune status and age of pigs, the immunogenicity of the vaccine, housing and the condition of the pig’s immune system.
