The Polypay sheep breed is a white, medium sized sheep which was developed in the 1960s at the U.S. Sheep Experiment Station in Dubois, Idaho.〔(Alberta Sheep Breeders' Association - Polypay )〕 In general, Polypay sheep are noted for being a highly prolific, dual-purpose (meat and wool) breed.〔 〕 ==Breed goals== Dr. C. V. Hulet created five main goals for the new breed.〔 〕 *High lifetime prolificacy *Large lamb crop at one year of age *Ability to lamb more frequently than once per year *Rapid growth rate of lambs *Desirable carcass quality The original breeding stock were taken from the Finnsheep for their high prolificacy, early puberty and short gestation, Dorset for their superior mothering ability, carcass quality, early puberty and long breeding season, Targhee for their large body size, long breeding season and quality fleeces, and Rambouilet for their adaptability, hardiness, productivity and quality fleeces. 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「Polypay」の詳細全文を読む スポンサード リンク
