If cattle and sheep have recognized lineage classes, they are specified like camels. If not, they are specified like donkeys (based on origin/locality). The species must always be mentioned; for camels, specifying Bakhiti or Arabi is necessary, and for sheep, specifying sheep (dhan) or goat (ma'z) is required, except for mules and donkeys, which have no distinct species division.
