Thoroughbred and Arabian Mare Requirements

Thoroughbred, Arab and Anglo-Arab mares are eligible for inspection and placement in the Studbook, with the potential to move into the Main Studbook through successful completion of the Mare Performance Test (MPT).

On the most recent tours, the inspectors remarked that the quality of the non-Hanoverian mares, particularly the Thoroughbreds was very good. The owners are now very aware of the exacting requirements for mares and why sufficient movement (impulsion and elasticity) is so important.

Why should I take my mare to a Hanoverian inspection?

Today’s Hanoverian horse is the result of a strict breeding program that dates back to the 1700’s! The American Hanoverian Society, an affiliate of the German Hanoverian Verband, requires both parents be approved for breeding to produce a foal eligible for registration. This selection process helps to ensure the production of a superior performance horse.

How do I know if my mare is eligible?

All Jockey Club-registered Thoroughbred mares, registered Arabian mares, and registered Anglo-Arab mares are eligible for breeding approval at an AHS inspection. The original Jockey Club or Arabian papers must be available at the inspection site for your mare to be inspected.

How is my mare judged?

The inspection is an evaluation of your mare’s conformation, gaits and movement. Your mare will be judged in hand, both standing still, and at the walk and trot on the triangle. A Thoroughbred, Arab or Anglo-Arab mare must score a 7 or higher for impulsion/elasticity as well as a 7.0 or higher overall (final score) with no subgroup below 5 to be accepted. A mare that is accepted will be entered into the Studbook.
