蒙古野马Poliakov(Poliakov，1881)人工繁殖已有10代。距离上一次确认目击到E已经过去了十多年。PRZEWALSKI在其历史范围内。对圈养繁殖这种濒危物种期间发生的近亲交配程度的关注，导致了许多关于将圈养种群作为遗传种群而不是孤立的种群进行管理的建议。1979年11月，北美普氏马饲养者举行了一次会议，当时所有饲养马匹的机构都审议并通过了一项协调的育种方案。在美国的Przewalski。作为这项协议的结果，动物园之间发生了一些动物迁徙，预计下一代小马驹的近亲繁殖程度将会下降。介绍了E.讨论了美国的Przewalski以及管理方案中涉及的遗传因素。
The Mongolian wild horseEquus przewalskii(Poliakov, 1881) has been propagated in captivity for ten generations. Well over a decade has passed since the last confirmed sightings ofE. przewalskiiin its historic range. Concern over the extent of inbreeding which has occurred during the captive propagation of this endangered species has led to numerous recommendations for management of captive stock as genetic populations rather than isolated collections. In November 1979 a meeting was held of North American Przewalski's horse breeders, at which time a coordinated breeding programme was considered and adopted by all institutions breedingE. przewalskiiin the United States. As a result of this agreement, a number of animal movements between zoos have occurred with a projected decrease in the extent of inbreeding of foals of the next generation. The history of propagation ofE. przewalskiiin the United States and the genetic considerations involved in the management programme are discussed.
