摘　　要：为了研究并提出肉用绵羊舍饲高频繁殖最佳畜群结构的优选方案,运用数学优选法原理和方法,结合宁夏当代肉羊生产的现状,对肉用绵羊畜群结构进行了系统调查分析。经计算优选出肉用绵羊舍饲高频繁殖生产最佳畜群结构中,能繁母羊的比例应在55%~60%之间选择。提示:以能繁母羊所占羊群比例60%为宁夏及同类地区肉用绵羊舍饲最佳畜群结构的优选方案。In order to study and put forward an optimal plan of herd structure for high-frequency reproduction of mutton sheep, the structure of mutton sheep herd was investigated and analyzed by applying the principles and methods of mathematical optimization and based on the current situation of mutton sheep production in the Ningxia area. The result was that the ratio of productive ewes to the herd should be between 55%-60% as the optimal herd structure of high-frequency reproduction of mutton sheep, and 60 % of productive ewes might be chosen as the optimal herd structure of a sheep group in the Ningxia area and other similar areas.
