The Guernsey is a breed of cattle used in dairy farming. It is fawn and white in color, and is particularly renowned for the rich flavour of its milk, as well as its hardiness and docile disposition.
As its name implies, the Guernsey was bred on the British Channel Island of Guernsey. It is believed to be descended from two breeds brought over from nearby France; Isigny cattle from Normandy and the Froment du Léon from Brittany. The Guernsey was first recorded as a separate breed around 1700. In 1789, imports of foreign cattle into Guernsey were forbidden by law to maintain the purity of the breed although some cattle evacuated from Alderney during World War II were merged into the breed.
Exports of cattle and semen were for a while an important economic resource for the island and in the early 20th century a large number of Guernsey cattle were exported to the United States. Today the breed is well-established in Great Britain, the United States, Canada, South Africa and elsewhere.
