Guernsey

Cattle

The Guernsey is a breed of cattle used in dairy farming. It is fawn and white in colour, and is particularly renowned for the rich flavour of its milk, as well as its hardiness and docile disposition. The unique qualities of the milk produced by the Guernsey cow have made the breed world famous. The milk has a golden colour due to an exceptionally high content of beta carotene. Beta-carotene is a source of Vitamin A, which has been touted to help reduce the risks of certain cancers. The milk also has a high butterfat content of 5% and a high protein content of 3.7%. Guernsey cows produce around 6000 litres per cow per annum. In the US Guernsey cows average 16,200 pounds of milk per year with 4.5% fat and 3.2% protein. Guernsey cattle are known to produce the highest percentage of A2 milk of all breeds of dairy cattle.
