Application of CSFV vaccines in a field farm with long-term observation. Pigs were divided into three groups and immunized with one dose of CSF-E2 vaccine (group K, n = 10) or placebo (group M, n = 10) at 4 weeks of age or two doses of LPC vaccine (group L, n = 10) at 12 and 16 weeks of age. The serum samples were collected from weaning to finishing in four-week intervals and analyzed using an IDEXX CSFV Ab blocking ELISA test kit. The gray dotted line represents the adequate antibody level (blocking percentage > 40%) and different letters indicate a statistically significant difference (p < 0.05)
