British White cattle are a breed of domestic beef cattle...

British White Cattle Association of America (BWCAA)
The North American Piedmontese Association (NAPA) was organized in September 2000, and is the official breed registry for North American Piedmontese cattle. It is a member-based, nonprofit breed registry headquartered in Washington, U.S., and the first cattle breed registry with mandatory registration requirements based on the presence of the Piedmontese-specific myostatin allele mutation. There are different categories of registration and recordation within the registry. Only homozygous animals (2 copy) can be registered, therefore breed true, and are eligible for registration in either the Fullblood (based on pedigree record), or Naturalean divisions.

The Naturalean division is for Piedmontese cattle that are either crossbred or could have qualified for Fullblood registration but failed to meet the pedigree requirements, perhaps because of unregistered or unverified parentage. Prior to registration or recording, DNA testing is required to confirm the animal carries at least 1 copy of the Piedmontese-specific myostatin gene. Naturalean animals that are DNA tested heterozygous (1-copy) are not registered, rather they are issued a registration number with the prefix "recorded". The 0-copy (non-carriers) cattle are ineligible for registration in any category.

According to the North American Piedmontese Cattle Association, in the last decade of the 20th century, there was a noticeable upsurge in the importation of genetic material (i.e., embryos and semen). Thus, it is said that "there are now a wealth of blood lines" available from which to choose.
