Breeding Stock Evaluation 

AHHA has also instituted amongst it’s policies a system to rate the horses within it’s registry. Horses are evaluated in their 3rd year, although some horses evaluate better in their 5th and 7th years as a mature horse.   This information will enable buyers, sellers and breeders to make informed decisions. 


AHHA is extremely dedicated to it’ s preservation efforts and will continue to work towards keeping horses within the breed standard.

Breeding stock that continually produce progeny which are outside breed standard, will no longer have progeny registered.  

This is not to say that there will not be occasionally atypical horses produced, however a continued presence of those sorts of progeny will effect registration ability.

Horses are rated by a minimum of 7  Spanish Mustang/ Heritage Horse experienced horsemen, judges or clinicians.  The horses are rate by phenotype only as by the time they have reached that level they will have qualified on pedigree. The rating does nothing to the registration except establish  an opinion of that animal as breeding stock.  The horses are judged blind. No pedigree, or names involved, the evaluators are given the sex and age of the horses.  The horses are then evaluated  strictly on phenotype and the  structural aspects of breeding animals.

AHHA will be requiring DNA typing for parentage/progeny testing on registered horses.  As of 2012 all AHHA animals will  be registered with DNA typing.  This is an effort to create a traceable database for  the horses, the breeders, and owner/buyer.

Breed Standard vs. Conformation

The conformation of the horse is how it relates form to function.  Conformation is more than the breed standard and  the breed standard is beyond conformation; they do however go hand in hoof.  Correct conformation is the same in any breed.  It relates to how well a horse holdups to stress on its body and how well it can move.    Conformation  includes such faults as ewe necks, sickle hocks, calf knees, week loin coupling, etc.
