Jersey cows produce up to 6 gallons of high-butterfat milk each day. Even though they are small cows, they produce more milk per pound of body weight than any other breed of cow. They accomplish this while eating less feed than many other breeds of cow.
The quality of milk produced by Jersey cows is the richest of all dairy cows. The high butterfat content of milk from Jersey cows makes it ideal for making butter and cheese. Milk produced by Jersey cows typically contains higher levels of protein, calcium, phosphorus and vitamin B12 than that of other cows. Jersey cows originally come from the island of Jersey in the English Channel.
