Cows that we raise for milk are called dairy cows. Most of them are the same breed (or kind) of cow: Holstein.
Cheese was first made more than 5,000 years ago. There are more than 1,500 different kinds of cheese made from the milk of cows, goats, sheep, and other animals.
Their feet are called hooves, which have two toes on each hoof.
Cows are in
the Bovidae family, which includes gazelles, antelope, buffaloes, and bison, as well as sheep and goats. At the National Zoo, you can see dama gazelles
and scimitar-horned oryx
