JERSEYS are the nation's second most popular dairy cow, with around 35,000 milkers, but number only a fraction compared to the black-and-whites.
A third of the Jerseys graze in the South West of England, with approximately 20 herds in North Devon.
Their milk, often sold as Gold Top, is prized by butter, cheese and cream processors, the breed society claiming that it contains 18% more protein, 20% more calcium and 25% more butterfat than "average" milk.

Jerseys are relatively small, weighing about 400 to 450kg, but still average 5000kg of milk produced per cow per year, with the best individual animals yielding around 9000kg or higher.
Now bred all over the world, Jerseys are typically light brown, sometimes with white patches, but can range from almost grey to dull black, known as Mulberry.
The breed has a black nose bordered by an almost white muzzle and hard black feet with a relatively low tendency to lameness.
