: The research was conducted by using data obtained through the information publicly available from Kanagawa Prefectural Government reports. All data or information excludes personally identifiable information such as farmers’ names. The pedigree information of the Holstein cows registered in Kanagawa was obtained from the DAI databank through web-search using their IDs. The dairy farm leaders gave verbal consent for the blood sample collection, serological test of BLV antibodies and PVL measurements. The serum samples and EDTA-treated blood samples used in this study were collected by KSLHS from 2015 to 2016 national whole herd test surveillance targeting <i>Mycobacterium avium</i> subsp. <i>paratuberculosis</i> (MAP) infection and Johne’s disease.
