In 1813, Arthur Young estimated 200,000 ewes were kept on the eastern South Downs and commented, "the amazing number they keep is one of the most
Breed registry conformation shows. For the breed to move to the Miscellaneous class and then to fully recognized status, the breed's stud book must be closed.

This may put a breed at a disadvantage, especially in performance disciplines, where an animal is worth more if it is successful in competition even if it is not pure. It also limits the gene pool, which may make certain undesirable characteristics become accentuated in the breed, such as a poor conformational fault or a
