Abstract: Livestock and poultry genetic resources are materially fundamental to the initial innovation and development of animal husbandry，and are pivotal means to enhancing the competitiveness of livestock and poultry breeding industry. Guangdong is rich in livestock and poultry genetic resources and has generated a strong comprehensive strength in corresponding breeding industry. Meanwhile，an increasing importance has been attached to the genetic preservation and management in recent years. We here introduced the current livestock and poultry genetic resources in Guangdong with regards to its scale，conservation techniques and methods，construction of preservation system，and major achievements of innovative development and utilization. Thus，the major problems that existed were analyzed，to which constructive solutions were proposed，expectantly providing a reference for the virtuous cycling pattern between preservation and utilization of livestock and poultry genetic resources.
