Should I DNA type my horse?

As equestrian sport forges on into the 21st century, using DNA (deoxyribonucleic acid) to verify parentage and ensure the accuracy of pedigrees has become an important part of preserving bloodlines in the sport horse industry. DNA typing is similar to blood typing for parentage verifications, with the exception that DNA typing is much easier. Unlike blood typing, DNA typing does not require a veterinarian to collect a sample.

DNA is replicated and passed on to offspring. As a result, there are fewer than 1 in 10,000,000 errors in DNA samples recorded. The PHR uses the University of California at Davis for DNA typing, one of the foremost facilities used in the nation. UC-Davis is widely used by other breed registries for the same purpose.

Upon registration, the PHR will automatically send a DNA typing kit, complete with instructions. All that is required is to remove 50-60 mane hairs from the root and ship them, along with the provided form, to the lab at UC-Davis for testing. The results of the DNA typing are then sent directly to the PHR.

The PHR requires DNA typing for all breeding stock. This is common among breed registries around the world. If your horse is a gelding, or is under the age of two, DNA typing is not required. However, should you decline DNA typing and later decide to use the animal for breeding, the horse must be DNA typed in order to make the foal eligible for registration.

If your horse has been DNA tested through another registry, you are not required to test again. Simply supply the PHR with a copy of the results or the case number and name of the registry.
