Vietnamese Pot-bellied is the exonym for the Lon I (Vietnamese: Lợn Ỉ) or I pig, an endangered traditional Vietnamese breed of small domestic pig.
The I is uniformly black and has short legs and a low-hanging belly, from which the name derives. The I is reared for meat. It is slow-growing, but the meat has good flavour. The I was depicted in the traditional Đông Hồ paintings of Bắc Ninh province as a symbol of happiness, satiety and wealth. Source: https://en.wikipedia.org/
