The Jersey is a British breed of small dairy cattle from Jersey, in the Channel Islands. It is highly productive – cows may give over 10 times their own weight in milk per lactation; the milk is high in butterfat and has a characteristic yellowish tinge.
The Jersey adapts well to various climates and environments, and unlike many breeds originating in temperate climates, it tolerates heat well. It has been exported to many countries of the world; in some of them, including Denmark, France, New Zealand, and the United States, it has developed into an independent breed.
