Percentage Programs

In addition to the Fullblood (100% Aberdeen) designation, the American Aberdeen Association provides three different percentage programs to help you achieve your cattle breeding goals.

Purebred

Purebred (87.5% to 99.99%) Purebred American Aberdeen cattle have been bred up by using registered Aberdeen percentage cattle. Purebred American Aberdeen cattle may exhibit some of the same characteristics of fullblood cattle but it is important to know that purebreds can never be bred up to be fullblood American Aberdeen cattle.

Multi-generational cattle are accepted as long as the breed and percentage criteria are met. Either the sire or dam (or both) of the first-generation Aberdeen Plus must be registered with the American Aberdeen Association®.
