Haptoglobin serum concentration (±SEM) at the different sampling times in fifty vaccinated (V) and fifty non-vaccinated (NV) pigs with a PCV2 vaccine at 3 weeks of age for farm A. PCV2-SD was diagnosed around 12 weeks of age by means of clinical signs, histopathological findings and detection of PCV2 in tissues.
