IDHSNA REGISTRATION CLASSIFICATIONS
The very best way to know if your purebred Irish Draught or partbred Irish Draught Sport Horse is eligible for registration or inspection is to inquire with the IDHSNA registrar. You may also contact the registrar to confirm registration status / eligibility of a planned breeding.
CLASSIFICATIONS FOR PUREBREDS
Registered Irish Draught (RID) – RID Classification is breeding approval and the highest classification available in North America until 2016. The classification RID refers to purebred horses that were inspected and approved for breeding before harmonization with HSI and/or before HSI adopted its new classification system of Class 1, Class 2, etc.
Class 1 Irish Draught (C1 ID) – C1 ID is breeding approval and the highest classification under the rules of harmonization. Horses that since harmonization have been inspected and approved and have met all of the veterinary and inspection requirements and were classified as Class 1.
-
Stallions that were approved by IDHSNA prior to 2001 were reclassified as Class 1 without x-rays or further inspection.
-
Stallions approved by IDHSNA 2001-2015 whose owner submitted acceptable x-rays were also reclassified as Class 1.
Class 2 Irish Draught (C2 ID) – C2 ID is breeding approval. Horses that have been approved and have met all of the veterinary requirements but have not met the inspection requirements for Class 1, are classified as Class 2.
Class 3 Irish Draught (C3 ID) – C3 ID Horses have not met the veterinary requirements. Offspring of Class 3 are not eligible for inspection.
Uninspected ID (Uninspected ID) – All purebreds are eligible for entry into the Irish Draught Horse Studbook and at initial registration enter as Uninspected ID. Purebreds remain in the “Uninspected” class until, if eligible, inspection, when they move into Class 1, Class 2, or Class 3. “Uninspected” is sometimes referred to as Class 4 outside IDHSNA. If a horse has one or both parents that are Uninspected, check with the registrar about eligibility for inspections.
Appendix Irish Draught (AID) – AID was a supplementary section of the purebred book open to mares only who were classified as AID prior to Dec 31, 2014. AID mares are a minimum of 3/4 approved Irish Draught blood. An AID can produce approved purebred mares and stallions.
Supplemental Irish Draught (SID) – SID was a supplementary section of the purebred book open to mares only who were 1/2 approved Irish Draught blood and were inspected and approved as SID. The SID book is closed.
NOTE: Some additional terminology for purebred Irish Draughts who are uninspected or not approved for Breeding which may be found on IDHSNA registration documents include: ID Foal, Non-breeding ID, Progeny-ID. These designations are indicative of the time period in which the horse was originally registered.
CLASSIFICATIONS FOR PARTBREDS
Irish Draught Sport Horses (IDSH) – This is the uninspected classification for Irish Draught Sport Horses in North America. To be eligible for the IDHSNA partbred studbook, an IDSH must have at least 1/8 Irish Draught blood from an approved source. IDSH has two sub- groups: IDSH TBx and IDSH Non-TBx.
In order to be placed in the TBx group, proof of registered Thoroughbred parentage or background must be documented.
-
Horses with any non-TB blood are classified as Non-TBx.
-
An IDSH horse must have 1/4 Irish Draught blood from an approved source to be eligible for inspection.
Registered Irish Draught Sport Horse (RIDSH) – RIDSH is breeding approval and the highest classification available in North America for partbreds. Irish Draught Sport Horses receive the classification RIDSH after they have been inspected and approved. An RIDSH must have at least 1/4 Irish Draught blood from an approved source. ID blood is verified with DNA.
Certificate of Pedigree (COP) – All COP horses are IDSHs. Horses receiving this classification were not eligible for standard registration at the time of their recording. These horses can be by or out of unapproved stock. There is no inspection process for horses with a Certificate of Pedigree.
If the Irish Draught or sport horse in the pedigree receives approval, the COP horse may become eligible for regular registration and possible inspection. Irish Draught heritage must be documented via DNA testing.
OUTSIDE IDHSNA
Irish Sport Horse (ISH) – ISH is a designation used by Horse Sport Ireland for ALL sport horses born in Ireland. These horses do not need to have any Irish Draught and they do not need to have a documented pedigree. It is a geographic designation.
