The I pig: From a symbol of Vietnamese prosperity to a global pet fad
In short: The I pig, a traditional Vietnamese breed known for its sagging belly and wrinkled black skin, was once a cornerstone of rural life in the Red River Delta. While it once numbered in the millions, it shifted from a valued agricultural asset to a short-lived international pet craze and endangered species.
The I pig, or Lon I, is a small, robust breed native to the Red River Delta in Vietnam. Historically, it was the dominant pig in provinces like Nam Dinh, Ha Nam, and Thanh Hoa. These animals are uniquely adapted to marshy environments, featuring plantigrade feet that distribute weight across four toes, allowing them to thrive on rice straw and aquatic vegetation. Culturally, the breed held significant status; traditional folk art from Bac Ninh province often featured the pig as an emblem of wealth, contentment, and abundance.
By the 1970s, the breed began a rapid decline as farmers favored the more productive Mong Cai pig. Despite conservation efforts by the National Institute of Animal Husbandry, which included subsidies for purebred rearing, the population plummeted. Estimates suggest numbers fell from 675,000 in 1991 to a mere 120 by 2010. By 2007, the Food and Agriculture Organization classified the breed as endangered, and its current status remains unknown as of 2025.
The breed's international journey began in the 1960s with exports to Canada and Sweden for zoos and research. By the mid-1980s, these pigs reached the United States, where they were marketed as exotic pets. This trend was fleeting and often involved crossbred animals that grew much larger than the typical 50 kg breed standard. This global movement eventually led to ecological complications; for instance, the pig was officially categorized as an invasive species in Spain by 2013.
Two distinct types exist within the breed: the I-mo, characterized by its short stature and small, upward-pointing ears, and the I-pha, which is taller with longer legs and horizontal ears. While their physical traits—such as their sway backs and heavy jowls—are iconic, their future in their native habitat remains uncertain after decades of displacement and genetic dilution.
