The Irish Horse Board Co-Operative Society maintained the Irish Horse Register, incorporating the Irish Sport Horse Studbook and the Irish Draught Horse Studbook, it also ran National Breeding and Marketing schemes since 1993. In late 2006, Horse Sport Ireland was established to bring the sport, breeding and leisure sides of the Sport Horse Sector together.

In 2008 a Special General Meeting of the Irish Horse Board Co-operative Society approved the Irish Horse Board’s integration with Horse Sport Ireland. In 2008 the maintenance of the Irish Horse Register became the legal responsibility of Horse Sport Ireland; this remains the situation to date.
