Requirements to stand at stud and the registration of progeny as full Standardbreds

Any entire horse wishing to stand at stud publicly or privately must comply with the following:

• Be registered as a full Standardbred with STAGBI


• Be DNA parentally verified to his sire and dam having a DNA profile on record in order to verify any progeny


• Have been examined by a vet who must confirm that the horse is fit and suitable for stud duties having identified the horse against his passport

To enable Owners or Studs to comply with the above once a full horse is registered then a Stallion certification pack may be requested free of charge from STAGBI.

This will contain the forms for your vet to fill in during his examination of the horse and a sample kit in order to collect a DNA sample. Both the forms and sample must be signed by the vet at the time.

The terms and conditions form must be completed by the owner or agent on behalf of stud.

The complete pack should be returned to STAGBI in the address envelope provided along with the fee of £50 to cover DNA and administration fees.

Once the DNA has been processed STAGBI will issue a Stallion Certificate valid for natural service.

Collection of semen for freezing or for transportation for use in A.I.

Stallions at Stud that are to have semen collected for the above will need to have full tests to comply with the regulations and recommendations laid down. Please click here for the regulations. .

Annual Stallion Returns

STAGBI require that every stallion owner must complete an annual stallion return of mares mated. Such returns should be made at the end of the mating season each year, and in all cases before 31 Dec in the year of mating (late returns will incur extra fees as below).

Return forms are posted to all stallion owners who have made a return during the last two years in the spring of each year, extra copies of annual return may be requested or downloaded by clicking here if you have not received one or need more forms.

To complete the forms enter the stallion name and number along with the Stud name and address.

Then for each mating complete each box with the broodmares name, registration number, owners name, and full address and date of mating from and to

In the interests of accuracy please use block letters and write clearly, as this information will be entered on our database and used to print mating certificates.

This has a twofold purpose in that it protects the stud owner and confirms that the mare presented was verified from its passport and mated to the named stallion.

Fee for each mating certificate: £10 if return received before 31 Dec in year of mating.

STAGBI will issue late or retrospective mating certificates however these will be charged at £25 each. If you require late returns please download the late return form.

STAGBI will print and post by first class mail, mating certificates to stallion owner, who will then forward the certificate and foaling return to the mare owner, this should only be done by the stud or stallion owner once all payments due for stud fees have been made,

STAGBI recommend that all broodmares should be scanned to confirm that they are in foal.

AI Returns
Stud and Stallion owners using A.I. need their vets or A.I. stations to complete the A.I. covering form for each mare and attach completed forms to annual stallion returns.

Please note: A certificate of mating only confirms that the mating took place and in no way gives any guarantee of a live foal.
