Assessment of biosecurity practices and adaptation of the evaluation system at mink farms using item response theory

The paper presents the results of a study on the implementation of biosecurity practices at mink farms in the Kyiv region, utilizing the Item Response Theory (IRT) methodology, which was adapted to assess the level of biosecurity and identify key aspects requiring improvement. The primary focus is on segregation, sanitation, and management practices, which are critical for minimizing the risk of infectious disease spread. The analysis revealed significant differences between the two studied farms. The first farm demonstrated substantial gaps in the implementation of measures, whereas the second farm exhibited a more stable level of biosecurity, though some aspects remain insufficiently implemented. The study's findings provide valuable insights for developing recommendations to enhance biosecurity standards and improve farm management efficiency.
