American guinea hog
We have a registered sow, Elsie, who came from the magnificent Flint and Steel Farm, which just happens to be right down the road!
The Livestock Conservancy describes AGH:
The name Guinea occurs again a few decades later in the southeastern United States, though describing a different animal entirely—a small, black hog common on homesteads across the region. Guinea Hogs were expected to forage for their own food, eat rodents and other small animals, grass, roots, and nuts, and clean out garden beds. The hogs were also kept in the yard where they would eat snakes and thus create a safe zone around the house. These Guineas were hardy and efficient, gaining well on the roughest of forage and producing the hams, bacon, and lard essential for subsistence farming.
