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.

Aberdeen Plus logo




Percentage cattle (25%-87.5%)—Percentage cattle with the non-Aberdeen portion coming from registered American Angus or American Red Angus. The member must supply the registered, genetic defect-free pedigree and appropriate fee to enter the foundation animal into the Aberdeen Plus registry. The submitting member must be the recorded owner of the female at the time the calf was born. A flush report is required for all embryo transplant calves. 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®.

Moderator®

Percentage cattle (50%-87.499%)—Both sire and dam of a Moderator must be registered with the American Aberdeen Association. Moderator shall be added to registration papers for these animals.

Moderator Plus®

Percentage cattle (25% to 50%)—Aberdeen genetics on at least one side of the pedigree and must be registered with the American Aberdeen Association. Either the sire or dam (or both) of a Moderator Plus must be registered with the American Aberdeen Association. Moderator Plus shall be added to registration papers for these animals.
