The invention provides a caprine herpesvirus I vaccine strain and an application thereof, and relates to the field of biological veterinary products. The caprine herpesvirus I vaccine strain is a caprine herpesvirus I JSHA1405 strain, which is preserved with preservation number of CCTCC NO:V201745. Virus liquid is obtained through multiplication of the virus (caprine herpesvirus I) by virtue of mardin-darby bovine kidney cells. The invention also provides an application fot eh vaccine strain in preparing caprine herpesvirus I vaccines. The caprine herpesvirus I JSHA1405 strain provided by theinvention is relatively strong in pathogenicity and is good in immunogenicity.
