PLEASE NOTE: As of 1 August 2007 the ET Mare Enrolment procedure is no longer rquired.  AQHA no longer require mares to be officially enrolled with the Association for ET.  Stallions still need to be enrolled for AI as per AQHA Rules & Regulations.

17.1 There will be no restriction on the number of progeny registrable as a result of embryo transfer/transplant procedures.

a) All donor mares involved in embryo transfer MUST be DNA typed prior to any embryo/s being collected.

c) The resultant foal must have its pedigree verified by approved DNA testing and by such other testing as the Association deems necessary, all expense of which shall be met by the registration applicant.

17.2 In accordance with Association-approved procedures, an embryo may be transported from the premises where the donor mare was located at the time of its removal from her, for use in a recipient mare at another location.

17.3 Progeny resulting from stored embryos or eggs will be eligible for registration in the Stud Book or Appendix Register provided all normal registration requirements are met.

17.4  When a foal is produced by embryo transfer, that fact will be noted on its registration certificate.

17.5 The Association may inspect the premises and practices of any party using or intending to use embryo transfer procedures.

Stallions still require Artificial Insemination (AI) enrolment as per the Associations Rules & Regulations.  All necessary forms for enrolling stallions for artificial breeding can be found in the forms area and information for using a stallion for AI can be found here.

Horses produced by any cloning process are eligible for registration in the Stud Book or Appendix Register of the Association providing such is declared to the Association and that it meets all registration requirements.

Cloning is defined as any method by which the genetic material of an unfertilised egg or an embryo is removed, replaced by genetic material taken from another organism, added to with genetic material from another organism, or otherwise modified by any means in order to produce a live foal.

When a foal is produced by cloning, that fact will be noted on its registration certificate.
