The American Rabbit Breeders Association is a national organization dedicated to the promotion, development, and improvement of domestic rabbits and cavies (guinea pigs). Founded in 1910, ARBA sets the standards for more than 50 recognized rabbit breeds and 13 cavy breeds. The organization provides resources for breeders, supports youth involvement, promotes responsible ownership, and hosts competitions and shows across the country. One of its key contributions is publishing the Standard of Perfection, a detailed guide that defines the ideal characteristics of each recognized breed. 

The American Dairy Goat Association (ADGA) is a national organization founded in 1904 that promotes the breeding, registration, and improvement of dairy goats in the United States. ADGA maintains official herd books and performance records for several recognized dairy goat breeds, helping breeders track lineage, milk production, and genetic progress. The organization also supports youth programs, educational events, and goat shows to encourage responsible ownership and excellence in dairy goat management. ADGA plays a major role in advancing the dairy goat industry through science-based standards and community engagement.
