The English is well-known for raising sheeps. There are over sixty different breeds of sheeps in the UK. Sheep has been raised in England for hundreds of years. Ninety per-cent of the sheep is raised for wool. Annually, from two to thirty pounds of wool are produced by one sheep. The wool from one sheep is called "a fleece", the wool from many sheep, "a clip". Genetics are one factor that determine how much wool a sheep will produce. Lamb produces less wool than mature animal.
While sheeps and goats have many similarities, they are different species. Telling the difference between a sheep and goat are easy — look at their tails. A goat's tail goes up but a sheep's tail hangs down. Most goat grow hair that do not require shearing or combing. Most sheep grow wool that need to be sheared annually. One sheep, named "Shrek", got out of its paddock and was not found for seven years. When the owner found and sheared Shrek, he produced 68 pound of wool, enough to make 20 men’s suits.
