Source-derived summary

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. It is reared for meat; it is slow-growing, but the pork 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.

History

The I is a traditional Vietnamese breed. It is thought to have originated in the province of Nam Định, in the Red River Delta. It was the dominant local pig breed in most provinces of the delta, and was widely distributed in Nam Định province and the neighbouring provinces of Hà Nam, Ninh Bình and Thái Bình, as well as in the province of Thanh Hóa immediately to the south, in the North Central Coast region.

Until the 1970s the I was probably the most numerous pig breed in northern Vietnam, with numbers running into millions. From that time, the more productive Móng Cái began to supplant it. The National Institute of Animal Husbandry of Vietnam started a conservation programme, with subsidies for farmers who reared purebred stock, but this had little benefit – there was some increase in numbers, but at the cost of increased inbreeding.

Editorial summary

“Vietnamese Pot-bellied” enters the record as small black pig from northern Vietnam. Crown Archives preserves that source wording while asking what Vietnamese, Pot-bellied and small can confirm, complicate or overturn.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current 226-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Vietnamese, Pot-bellied and small.
Editorial analysis

Why this record matters

“Vietnamese Pot-bellied” is worth following because a concise public description often conceals a longer documentary argument. Here, Vietnamese, Pot-bellied and small provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 22, 2025. The linked authority identifier is Q945552. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
