PROCEDURES

Registering a Horse

In order to be defined as a Pure Blood Lusitano or PSL (Puro Sangue Lusitano) both parents must be registered/inscribed with the APSL (Associação Portuguesa de Criadores do Cavalo Puro Sangue Lusitano). Both parents must have a Breeders Section (LA/LGA) number. If one or both parents do not have a Breeders Section (LA/LGA) number your horse is NOT able to be registered as a Pure Blood Lusitano. If you are having trouble finding this information, please contact our registry office for further assistance at This email address is being protected from spambots. You need JavaScript enabled to view it..

Once you have obtained both sire and dam’s Breeders Section (LA/LGA) number follow these steps.

  • 1. In order to start the registration process, you must sign up for a USLA account. This can be completed by clicking on the “Log In” button located on the top right of the website. From there you can either login to your existing account or click “Don't Have an Account?” to create a new account.
  • 2. Once you are logged in all of the forms will be available under the Forms menu.
  • 3. Complete the Horse Registration Form and submit to USLA. When choosing a name for your horse, it cannot exceed 24 characters including letters, signs, and spaces. The first letter of the name should correlate with the year of birth (K, W, and Y cannot be used as the first letter of the name). For example: In 2021, names begin with the letter “R” and in 2022, names will begin with the letter “S”.
  • 4. After submitting, a Horse Diagram Form PDF and DNA Hair Submission Form will be sent to the email on file. These forms are for your Vet to complete and sign before sending to USLA.
  • 5. DNA parentage MUST be verified and the horse MUST have a microchip. You may supply your own microchip (with approval) or they can be purchased through our online store. Microchips are not currently available to Canada.
  • 6. Once USLA receives the completed Horse Diagram Form and DNA sample, DNA is then sent to the lab for parentage verification. Once parenatge verification has been completed all of these items are then forwarded to the APSL in Portugal.
  • 7. Once the APSL has accepted and approved the forms a Birth Section (LN/LGN) will be assigned and your horse will be inscribed/registered with the APSL.
  • 8. You will receive your horse’s registration papers in the mail.


  • *Please keep in mind, all forms have to be sent to Portugal. The process can take a few months to complete and receive your physical papers. We HIGHLY recommend starting this process when horses are 6 months of age or younger. If you are getting your horse registered/inscribed in order to be inspected this process must be started at least 8 months prior or there is no guarantee paperwork will be completed in time for inspection*

    DNA Parent Verification

    In order to register a Lusitano for the first time with APSL, DNA profiles and parentage verification by UC Davis and/or Alter Real Laboratory is required. DNA samples must be collected by your veterinarian and submitted with the Horse Diagram form. Your vet is signing off that the horse on the diagram, is the horse the sample was collected from. USLA does not accept outside DNA reports, all new registrations will require DNA testing through USLA. DNA profiles and parentage verification is done by pulling 20 to 30 mane or tail hairs with root follicles intact. Detailed instructions will come with your test kit. It is very important to provide the correct name and identity number of the horses parents, otherwise parentage will come back as “NOT qualified as an offspring from this sire and dam” and registration cannot be completed.

    Microchip Identification

    APSL requires that all horses be uniquely identified with a 15 digit ISO 11784/11785 compliant microchip code. Microchips starting with the prefix 900 cannot be used because these chips could have duplicate numbers. Prior to registration, the microchip number must be read and verified by a veterinarian on the Horse Diagram Form. If your horse has a pre-existing microchip that is not ISO 11784/11785 compliant a new compliant microchip may need to be placed. Microchips may be purchased from the USLA online store or purchased independently as long as they are ISO 11784/11785 compliant. Microchips are not currently available to Canada through USLA.

    Application for Inspection

    Please make sure the following requirements have been met prior to applying for inspection.

    Stallions:
  • 1. Registered/inscribed with the APSL with Birth Section number (LN).
  • 2. Must be 4 years of age or older.
  • 3. Must be under saddle and able to be ridden at a walk, trot and canter.
  • 4. Semen Report submitted to USLA.

  • Mares:
  • 1. Registered/inscribed with the APSL with Birth Section number (LN).
  • 2. Must be 3 years of age or older.
  • 3. Able to be free lunged at a walk, trot and canter.

  • *Geldings are not presented for inspection. Inspections are for the approval of breeding stock only.

    After completing the Application for Inspection Form members will be contacted by a USLA representative to finalize inspection dates. Breeders may choose to participate in an inspection event with several breeders or host a private inspection arranged by USLA. When participating in an inspection event, the judge fees and expenses will be divided amongst the breeders and prorated depending on the number of horses per breeder. If the breeder chooses to host a private inspection, they will be responsible for all of the judge fees and expenses. Dates for inspections are communicated through USLA newsletters, on the website and on the Facebook events page.

    Transfer of Ownership

    Pure Bred Lusitanos with registration in the APSL Book of Births or Book of Adults must be registered to their new owners before they can compete, be graded, or have any young stock attributed to them. You can only change ownership from the previous registered owner to a new owner, in some cases this may take more than one document. Transfer of ownership must be sent to APSL and not delivered to the buyer/new owner. To begin the process of tranferring a horse from a current owner to new owner this form should be completed by the seller. After this form is submitted the buyer and seller will be sent an electronic document by email to be signed to finalize the request.

    Reduction of Breeding Stock

    The Reduction of Breeding Stock allows APSL to update the breeding stock of each breeder. Breeder’s should complete the Reduction of Breeding Stock form when a breeding horse is no longer a part of their breeding program. The reasons may include Death, Castration, or Sale. In the event that a breeding horse has been sold please file the Transfer of Ownership Form.

    Statement of Coverage

    The Statement of Coverage is used by APSL to identify and track the mares and stallions bred, the type of breeding, and the percentage of fertility. The form is required to be submitted by breeders to USLA annually by the end of each calendar year.
