摘　　要：岷县黑裘皮羊是甘肃省特有的绵羊品种,生长在高海拔、空气稀薄、气候多变、枯草期长的自然条件下,由于生长环境和羊群特点,存在着群体规模小、饲养分散、经营效益低下,种群的家系血统来源单一,造成品种退化严重,种质资源存在灭绝的风险。岷县黑裘皮羊保种扩繁关键技术研究项目通过构建“一场七群保种繁育体系模式”进行品种选育扩繁提高,经过3年运行,在种群数量,品种质量等方面取得了明显的成效。本文详述了项目实施的体系构架、运行情况、运行成果、项目措施,并提出了保种建议。希望能进一步推动岷县黑裘皮羊的保护与利用工作。Minxian black fur sheep is a unique sheep breed in Gansu Province,which grows under the natural conditions of high altitude,thin air,variable climate,and long dry grass period.Due to the growth environment and characteristics of the flock,there are small population sizes,scattered breeding,low operating efficiency,and a single pedigree origin of the popula-tion,resulting in serious degradation of the breed and the risk of extinction of germplasm resources.The key technology re-search project of Minxian black fur sheep conservation and expansion has improved the breeding and breeding of the breed by establishing a“one field and seven groups”conservation and breeding system model.After 3 years of operation,significant a-chievements have been made in terms of population size and breed quality.This article discusses the system structure,opera-tion,operation results,measures taken by the project,and proposes conservation suggestions on seed preserration.It is hoped to further promote the protection and utilization of Minxian black fur sheep.
