They're the perfect size for the family homestead. One Dexter cow will give about 1 to 2 gallons of milk a day. If you raise a Dexter for beef, you'll need room in the freezer for about 400 pounds of meat, rather than 600 to 800 pounds you'd get from a typical full-size steer. Owning a Dexter is like owning a piece of history and doing your part to help preserve genetic diversity. They are one of the world's smallest true breeds of cattle, not a miniature developed from a larger breed.
