A livestock enclosure is a structure used to contain and protect animals, such as cattle, sheep, and horses. The two most common types of livestock enclosures are kraals and pens. A kraal is an African term for a circular enclosure made of stones, wood, or other materials, while a PEN is a smaller, more enclosed structure made of wood, metal, or other materials. Both types of enclosures provide protection from predators and the elements, and can be used to keep animals contained and safe.
