Breeds of horse #3 Thoroughbred

  The Thoroughbred Breed was originally bred to race under saddle, but now this highly versatile breed is used in cross country competitions, dressage, and many other Equine sports.

  Thoroughbreds range from 16Hh, to 17Hh.  They have a smooth face (no dished face like an Arabian's) with a rounded nose.  Their necks are slightly longer than the average horse, and their shoulders are well defined and sloped.  They have a slim figure with a deep girth, short back, and muscular hind quarters.

  The TB is recognized by the Jockey Club to come in the following colours:
Bay, Black, Chestnut, Dark bay, Brown, Grey, and less commonly, Roan, Palomino, and "White".  They can have facial and leg markings, and some rarer markings such as "catch-a-bird-spots".

  Thoroughbreds originated in England around the 1700's.  Each Thoroughbred can trace his or her lineage back to one of the three "foundation sires": The Godolphin Arabian, The Darley Arabian, and The Byerley Turk.

  The Thoroughbred, like it's foundation breed the Arabian, is considered to be "hot blooded".  Now obviously horses are mammals, and all mammals are warm blooded, so why "hot blooded"?  Hot blooded has nothing to do with body temperature, it just refers to the temperament of the breed.  Thoroughbreds are agile, fast, athletic racers, whereas a "coldblooded" horse would usually be a draft horse of some sort. Warm bloods are in-between the two temperaments.
