The International Stud Book Committee...

...the body which establishes the standards by which all Thoroughbred Stud Books agree to operate.

Welcome to the ISBC


Welcome to the website of the International Stud Book Committee (ISBC), the body which establishes the standards by which all Thoroughbred Stud Books must operate. Here you will find a variety of information from Approved Thoroughbred Stud Book contacts, to a brief history of the Thoroughbred and a list of the decisions taken since the Committee’s inception in 1976.

Since that inaugural meeting the ISBC has developed a set of policies that have enabled buyers to purchase horses safe in the knowledge the stated pedigree has been verified, now using the latest DNA technology, and that those same horses can cross national borders permitting them to race and breed with a minimum of documentation.

The nine member countries of the ISBC meet annually in Newmarket in the week prior to the International Federation of Horseracing Authorities’ Paris Conference. Decisions taken in Newmarket can then be disseminated to the relevant Racing Authorities who depend on the integrity of the breed as the basis upon which they race. Those nine Member countries are the Stud Book Authorities from Australia, France, Great Britain & Ireland, India, Japan, New Zealand, the United States of America, Canada & Puerto Rico, Southern Africa, and representing South America the Organizacion Sudamericana de Fomento del Sangre Pura De Carrera.
