Foalbook (vb) generally includes foals
Register B (Reg B) generally includes foals
Auxiliary Foalbook (hvb) - Since 2003 foals have been not been registered in the Auxiliary Foalbook but in either Register A or B. Starting 2008, Auxiliary Foalbook horses can no longer be inspected for Auxiliary Studbook. Auxiliary Foalbook mares that now qualify for Foalbook or Register A because of a change in the registration of the lacking parent, may be eligible for studbook inspection if the requirements are met.
Certificate of Pedigree (CP) - Starting in 2008, Certificate of Pedigree papers are no longer issued and foals instead receive Register B papers. Also since 2008, Certificate of Pedigree mares can no longer be inspected for Auxiliary Studbook. A Certificate of Pedigree mare that qualifies for Foalbook due to a change in the registration of one or both parents, may be eligible for studbook inspection if all requirements are met. (See box at bottom of page.)
Outside mares - Mares registered with an Erkend studbook may be eligible to have Foalbook registered foals. Mares registered with an Erkend studbook are also eligible for studbook inspection at age three or older. Pedigrees must be approved, parentage must be proven through DNA typing and they must pass the necessary veterinary and/or performance requirements. Successful outside mares will be entered in the KWPN studbook and have their original registration paper stamped with their KWPN status.
The KWPN also has books into which horses may be accepted:
Studbook (stb) - Foalbook and Register A mares, geldings and stallions are eligible for Studbook Inspection at age three or older. Register A stallions must complete all requirements for approval (radiographs, endoscopy and/or performance). Register A mares and geldings must complete those requirements not met by their sire (see box below). Upon successful presentation, mares and stallions are accepted into the studbook but geldings remain in or move to the Foalbook since they are not used for breeding. All successful horses will receive updated papers and may be branded with the lion brand on the hip.
Auxiliary Studbook (hbs) - Since 2008 horses are no longer accepted into the Auxiliary Studbook.
Licensed (L) - In the past these were Foalbook, Register A or Erkend Studbook registered stallions that had been successfully been presented at a KWPN-NA keuring for Approval and that had also passed the radiograph, endoscopy and semen requirements. Licensed stallions were not yet accepted into the Studbook. This status has now been replaced by “Aangewezen” although there are still a few cases where Harness stallions have this status.
Aangewezen (G) - These are Foalbook, Register A or Erkend Studbook registered stallions that have been successfully been presented for Approval at a KWPN-NA keuring and that have passed the radiograph, endoscopy and semen requirements. Aangewezen stallions have not yet passed a KWPN performance test (either a 21-Day or a 5-Day test).
Approved (A) - KWPN or Erkend Studbook registered stallions that have successfully been presented for Approval, have passed the KWPN veterinary requirements and performance test requirements. Approved stallions have been accepted into the Studbook.
Outside stallions - Stallions are registered with a KWPN Erkend studbook. These stallions are considered to be ‘improvement’ sires and are eligible for stallion approval at age three or older. Pedigrees and sport and/or offspring reports must be approved prior to keuring presentation.
The Jockey Club is considered to be an Erkend Studbook. Thoroughbred stallions may be presented for “Erkend” status.They must have their pedigree and performance records approved as a prerequisite for presentation. If successful the stallion will be designated ‘Erkend’.
