Part of my policy was to make my bulls affordable to commercial breeders, to pay an extra $200. for exactly the same bull just for papers when the buyer is not breeding pedigrees himself, just made no sense.
The origonal Aberdeen Angus have been bred pure with no upgrading option since the foundation of the breed. The American Angus has some influence from other breeds, making them a larger framed breed, and less standard in their phenotype.
Selection of the heritage bulls is the responsibility of the breed society, ensuring no lowering of the selection standards, especially when the demand is high and there is a temptation to pass slightly lower quality bulls to help meet the demand.
