The Shire horse is a breed of draught horse (BrE) or draft horse (AmE). The breed comes in many colours, including black, bay and grey. They are a tall breed, with mares standing and over and stallions standing and over. The breed has an enormous capacity for weight pulling, and Shires have held the world records for both largest overall horse and tallest horse at various times. Throughout its history, the breed has been popular for pulling brewery wagons delivering ale to customers. This practice continues today, with the breed also being used for forestry, leisure and promotional pursuits. In 1878, the British organization now known as the Shire Horse Society was created, with the American Shire Horse Association beginning in 1885. The breed was exported from Britain to the United States in large numbers during the late 19th and early 20th centuries, but popularity fell as mechanisation increased, reaching a low point in the 1950s and 60s. Popularity began to increase again in the 1970s and after. However, population numbers are still considered to be at critical levels by both the UK-based Rare Breeds Survival Trust and the US-based American Livestock Breeds Conservancy. ==Characteristics== Shire stallions may be black, bay or grey. They may not be roan or have large amounts of white markings. Mares and geldings may be black, bay, grey or roan. In the UK stallions may not be chestnut,〔(【引用サイトリンク】title=Standard of Points for Shires )〕 but the colour is allowed by the US registry.〔(【引用サイトリンク】title=ASHA Standard of Conformation Guideline )〕 Stallions must stand at least high when mature, and they average around . Geldings stand at least high and mares at least . Their average weight ranges from 〔 The head of a Shire is long and lean, with large eyes, set on a neck that is slightly arched and long in proportion to the body. The shoulder is deep and wide, the chest wide, the back muscular and short and the hindquarters long and wide. Not too much feathering is to occur on the legs, and the hair is fine, straight, and silky.〔 Smaller Shires, under , are generally preferred for working horses, while taller horses, especially those over , are used for show and promotional purposes. The breed is known for its easy-going temperament. Shires have been identified to be at risk for chronic progressive lymphedema, a chronic progressive disease that includes symptoms of progressive swelling, hyperkeratosis, and fibrosis of distal limbs. The disease is similar to chronic lymphedema in humans.〔(【引用サイトリンク】title=Chronic Progressive Lymphedema (CPL) in Draft Horses )〕 The Shire has an enormous capacity for pulling weight. In 1924, at a British exhibition, a pair of horses was estimated to have pulled a starting load equal to 45 tons, although an exact number could not be determined as their pull exceeded the maximum reading on the dynamometer. Working in slippery footing, the same pair of horses pulled 16.5 tons at a later exhibition. The largest horse in recorded history was probably a Shire named Mammoth, born in 1848. He stood high, and his peak weight was estimated at . At over , a Shire gelding named Goliath was the Guinness Book of World Records record holder for the world's tallest horse until his death in 2001. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「shire horse」の詳細全文を読む スポンサード リンク
