This can be done on General Stud Book Online and is an important process for ensuring mares and their progeny can be registered into The General Stud Book for racing and breeding purposes.

If a mare is covered in Ireland but the foal is due to be born abroad, then the mare doesn’t need to be registered with us, but with the Stud Book Authority in the country the foal is born.

If you acquire a mare that has already been registered as a broodmare, and wish to continue breeding to Weatherbys registered stallions, please visit General Stud Book Online to register ownership.

Alternatively, please download, complete and return the Broodmare Change of Ownership form below with the mares’ passport and the indicated fee.

It is requested that you advise us when a broodmare dies and return the passport, which will be recorded as void.

For any questions or queries related to broodmares please contact us on studbookireland@weatherbys.ie or call +353 (0)45 879979.
