Animals in a yoke refers to OXEN, which are animals that are harnessed together and used to pull heavy loads. OXEN are typically two-horned, domesticated bovines, such as cows, bulls, or steers, that have been trained to work together as a team. They are often used in agriculture to pull plows, carts, and other heavy equipment. OXEN are also used in some parts of the world for transportation, such as in India and Nepal.
