Why are farmers breeding wool-shedding sheep?

REPORTER: "This is a very special herd of sheep. On this farm in the southwest of England, one sheep farmer is breeding the sheep of the future."

NARRATOR: These sheep shed their wool by molting in the spring. In other words, they never need to be sheared. That also means that their wool can't be used. Well, except by birds, which use it to line their nests. But isn't this a terrible waste of a natural commodity?

SHEEP FARMER: "Well unfortunately, wool is no longer a valuable commodity. We bred sheep over the millenia to have a big, wooly fleece which has been very valuable. But wool commodity prices have fallen in recent years so that now it actually costs more to shear the sheep than the wool is actually worth."

NARRATOR: As sheep nowadays are only being bred for their meat, sheep farmers have had to get a little inventive. In many parts of Britain, these images are increasingly becoming a thing of the past. More and more farmers are now raising herds of so-called exlana sheep. The exlana is a cross between British sheep and breeds from warmer places where sheep naturally have thinner coats to cope better with the higher temperatures. The global economic downturn has led to creativity in all fields. Before long, British sheep shearers may well be a thing of the past as molting sheep take over the British countryside.
