From Cow

The Jersey breed originated over 600 years ago on the Island of Jersey, located in the English Channel between France and England. Today, outstanding herds of Jerseys can be found from Denmark to New Zealand, from Canada to South America, and from South Africa to Japan.

Jersey milk has a rich, smooth flavor because it naturally contains higher percentages of protein, calcium, and other important nutrients than milk from other dairy breeds. The extra protein is the reason Jersey milk yields the greatest amount of cheddar cheese.

The Jersey is the most efficient dairy producer in the world, producing more pounds of milk per pound of body weight than any other breed.
