From: Serum haptoglobin dynamics in pigs vaccinated or not vaccinated against porcine circovirus type 2
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 B. A clinical outbreak of colibacillosis and clinical signs of porcine respiratory disease complex were recorded at 10 and 23 weeks of age, respectively. No PCV2-SD was diagnosed in farm B.
