摘      要：Poultry genetics resources,including commercial selected lines,indigenous breeds,and experimental lines,are now being irreversibly lost at an alarming rate due to multiple reasons,which further threats the future livelihood and academic *** of germplasm may reduce the risk of catastrophic loss of genetic diversity by guaranteeing that a pool of genetic variability is available to ensure the reintroduction and replenishment of the genetic *** setting up of biobanks for poultry is challenging because the high sensitiveness of spermatozoa to freezing–thawing process,inability to cryopreserve the egg or embryo,coupled with the females being heterogametic *** progress in cryobiology and biotechnologies have made possible the extension of the range of germplasm for poultry species available in cryobanks,including semen,primordial germ cells,somatic cells and *** this review,we introduce the state-of-the-art technologies for avian genetic resource conservation and breed reconstruction,and discuss the potential challenges for future study and further extending of these technologies to ongoing and future conservation efforts.
