Since 1996, the Lanyu miniature pig and the Lee-Sung pig have been the only two miniature pig breeds from Taiwan to be registered by the UN Food and Agriculture Organization. And of these, the Lanyu miniature pig is the only pure local Taiwanese pig.
自 1996 年以降，「蘭嶼豬」與「李宋豬」，是我國唯二登錄在聯合國糧農組織（FAO）家畜品種目錄迷你豬種下的小型豬，其中，蘭嶼豬更是唯一的純種台灣本地豬。
