Kentucky Thoroughbred Development Fund (KTDF)

The Kentucky Thoroughbred Development Fund consists of money allocated to the fund through an excise tax imposed on all tracks conducting pari-mutuel wagering under the jurisdiction of the Kentucky Horse Racing Commission.

Each year, by July 1, the Kentucky Horse Racing Commission appoints an advisory committee to assist in the development of the supplemental purse program for Kentucky-bred thoroughbreds.  Additionally, the committee is charged with establishing guidelines for which the purses are to be administered to promote, enhance, improve and encourage development of thoroughbred breeding in Kentucky.

The Kentucky Thoroughbred Owners and Breeders, Inc. is recognized as the sole official registrar for the KTDF.  For questions regarding the registrar or to nominate to the KTDF, contact the Kentucky Thoroughbred Association (KTA) and Kentucky Thoroughbred Owners and Breeders (KTOB) at 859-381-1414 or visit
