VGL is the Veterinary Genetics Lab at the University of California-Davis, the premier genetics testing service in the U.S. This is the company that performs DNA testing for a variety of species, breeds, associations, and individuals, including the AMGR. When a breeder has a goat DNA tested, it is issued a VGL or file number. If that animal is registered with the American Meat Goat Registry, that VGL number will be displayed on the certificate of registration.
