The
Jersey breed originated on the Island of Jersey, a small British island in
the English Channel off the coast of France. The Jersey is one of the
oldest dairy breeds, having been reported by authorities as being purebred
for nearly six centuries.
The breed was known in England as early as 1771 and was regarded very
favorably because of its milk and butterfat production. At that early
date, the cattle of Jersey island were commonly referred to as Alderney
cattle although the cattle of this island were later referred to only as
Jerseys. Jersey cattle were brought to the United States in the 1850's.
They are more tolerant of heat than the larger breeds. With an average
weight of 900 pounds, the Jersey produces more pounds of milk per pound of
body weight than any other breed. Most Jerseys produce far in excess of 13
times their bodyweight in milk each lactation.
