The term 'sheep or goat' refers to a type of mammal known as a bovid, which is a member of the Bovidae family. Bovids are typically hoofed animals that are found in many parts of the world, including Africa, Asia, and Europe. They are usually herbivores, and their diet consists mainly of grasses, leaves, and other vegetation. Sheep and goats are two of the most common bovids, and they are often kept as livestock for their meat, milk, and wool.
