Cultural Connection

The Guinea Forest Hog is a heritage breed of domestic farm pig, bred for almost 200 years. They were developed as a landrace breed throughout the Southeast. They thrive where ranging and grazing is a constant activity giving them plenty of exercise. Also known as the Pineywoods Guinea, Guinea Forest Hog, Acorn Eater, and Yard Pig, the breed was once the most numerous pig breed found on homesteads in the Southeast.

Conservation Status

Considered threatened by the Livestock Conservancy. Fewer than 200 individuals left throughout the US. These hogs are not being raised often due to being smaller and fattier than is preferred for the mass production farming of today.

Be the Change

Guinea Hogs are appropriate for use in diversified, sustainable agriculture. They would be an excellent choice where there is need for the services of hogs (such as grazing, rooting, tilling compost and garden soil, and pest control) and also the desire for a small breed. For those considering starting a small sustainable family farm of their own, the Guinea Forest hog is exceptionally calm and friendly making it an excellent choice. They have exceptional mothering skills. Females with piglets are easily managed, as are adult males. They do well with children and a wide range of farm animals.

Fascinating Facts

The hogs were kept in the yard where they would eat snakes and thus create a safe zone around the house.

Hogs like wallowing in mud, because it helps keep them cool. Hogs have few sweat glands, high body fat and a barrel-shaped torso that stores heat. Wallowing can lower a hog’s temperature by 4 degrees. A mud bath is more cooling than a dip in cold water, because the water in mud evaporates offs the hog’s body more slowly.
