Assisted breeding technology will provide a new paradigm for solving problems associated with the preservation and management of captive and wild Koala populations. This project aims to improve methods of koala sperm cryopreservation and its subsequent use in artificial insemination and to establish a functional frozen sperm bank screened for the most prevalent pathogens. Important outcomes will include (1) a reliable, cost effective and disease free approach to the transfer of Koala genetic material into international and national zoos; (2) a technique for the management of free-range genetically restricted Koala populations and (3) successful cryostorage of Koala spermatozoa for the long-term maintenance of genetic potential.

辅助育种技术将为解决与圈养和野生考拉种群的保护和管理相关的问题提供一个新的范例。该项目旨在改进考拉精子的冷冻保存方法及其在人工授精中的应用，并建立一个具有功能的冷冻精子库，以筛选最流行的病原体。重要成果将包括(1)以可靠、成本效益高和无疾病的方式将考拉遗传物质转移到国际和国家动物园；(2)管理自由放养的遗传受限考拉种群的技术；(3)成功冷冻考拉精子，以长期维持遗传潜力。
