What is a ruminant with woolly coat used as beast of burden?

The animal you are describing is a Bactrian camel. Bactrian camels are large, even-toed ungulates that are native to Central Asia. They are ruminants, which means that they have a four-chambered stomach that allows them to digest plant matter. Bactrian camels have two humps on their backs, which are made of fat and are used for energy storage. They also have a thick, woolly coat that helps to protect them from the cold desert climate. Bactrian camels are often used as beasts of burden, and they can carry heavy loads for long distances.
