Livestock

Domesticated animals held as farmed subjects: the major livestock species and the named breeds bred from them, each carried with scientific name, domestication region and era, and primary uses. The tree under this category follows the FAO and DAD-IS livestock species classes (cattle, buffalo and yak, sheep, goats, pigs, equines, poultry, camelids, rabbits, and the minor species such as silkworms, honey bees and farmed carp), read against this atlas own live livestock list. A named breed (Angus Cattle, Merino, Duroc Pig) is grouped under its base species rather than given its own top-level category, since a breed is a variant within a species tree, not a separate species. Does not belong here: the wild ancestor species studied as wildlife, which is Nature own subject, or the animal as meat, dairy or another finished food, which is Food own subject.
