The Isle of Guernsey in the British Channel, is believed to be the motherland of Guernsey Cows, which were shipped to it by Norman monks in around 960 B.C., who helped the natives cultivate the soil and fight against enemies. Present day Guernsey Cows have undergone significant changes due to artificial insemination. It is notable, that these cows consume 30% less food than other species and produce a fairly large amount of milk.
