| 摘要 | [Objectives] This study was conducted to evaluate the immunization efficacy and infection status of classical swine fever (CSF), foot-and-mouth disease (FMD), porcine reproductive and respiratory syndrome (PRRS), pseudorabies (PR), and porcine circovirus type 2 (PCV2) in large-scale pig farms. [Methods] Antibody and pathogen detection was performed on 56 serum samples collected in March 2025. [Results] The antibody qualification rates for CSF, FMD, and PRRS were 76.8%, 73.2%, and 76.8%, respectively, all meeting the national standards. However, nursery pigs exhibited an immunity gap, indicating a need for timely booster vaccinations. No PRV gE antibodies or PCV2 antibodies were detected, reflecting the absence of vaccination against these diseases and suggesting significant effectiveness of comprehensive biosecurity measures. The low antibody qualification rate for PRRS in the nursery stage highlights the need for improved immunization management. [Conclusions] This study provides data support and practical insights for integrated disease prevention and control in large-scale pig farms. |
