The Ryeland is one of the oldest English sheep breeds going back seven centuries when the monks of Leominster in Herefordshire bred sheep and grazed them on the rye pastures, giving them their name. It was introduced into Australia in 1919 and are classified as an endangered breed by the Rare Breeds Trust of Australia and also are one of the nine heritage breeds〔(Heritage Sheep Australia )〕 that were the foundation of the sheep and wool industry in Australia. The Ryeland was one of the breeds used to introduce the poll gene (no horns) to the Dorset breed in the development of the Poll Dorset.〔 〕 This breed is raised primarily for meat.〔 〕 == Breed characteristics == Ryelands are docile with high fertility.〔 〕 Due to their blocky build they are easy on fences compared to many breeds. They are ideal sheep for small properties. Ryelands are also 'good -doers' – William Youatt wrote that Ryelands "endure privation of food better than any other breed" and Sir Joseph Banks wrote "Ryelands deserve a niche in the temple of famine".〔 〕 Ryelands have a smaller head than most terminal sires which makes them a good choice for maiden or Merino ewes but they have a fast growth rate and early maturity. In Australia the wool is always white and free of kemp. A coloured gene does occur in Great Britain but appears to be unknown in Australia. The hooves are black and they are said to have good resistance to footrot. Naturally hornless, the Ryeland was the major breed used in the development of the poll gene in the Poll Dorset in Australia. The wool resists felting. The staple length is generally 8 cm to 10 cm, with a fibre diameter of 25 to 28 microns.〔''Preparation of Australian Wool Clips'', Code of Practice 2010–2012, Australian Wool Exchange (AWEX), 2010〕 The fleece on average weighs 2 kg to 3 kg.〔 〕 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「Ryeland」の詳細全文を読む スポンサード リンク
