Abstract: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 population,resulting in serious degradation of the breed and the risk of extinction of germplasm resources.The key technology research 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 achievements have been made in terms of population size and breed quality.This article discusses the system structure,operation,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.
