Abstract: Objective Establish specific pathogen-free Anas platyrhyncha var.domestica breed populations. Method Highly quality breed species of Shaoxing Shedldrake No. I and Jinding duck breed eggs were based on as original populations, various biological purification measures were adopted, including eliminated specific avian diseases antibodies and antigen positive individuals, immunized with killed vaccines, raised in positive pressure high efficiency particulate air filter, fed with 60Co-treated feed, acidified water, strictly controlled the flow of people and logistics. Simultaneously, tests of molecular genetics, biological characteristics and disease susceptibility were carried out to standardize the ducks. Result HBK-SPF and SPF-JD duck breed populations with specific pathogens-free, clear genetics background and disease susceptible were successfully established. Conclusion The established specific pathogen-free duck breeds will enrich Chinese laboratory animals resources and provide important support for life science research and development of biological products.
