Abstract:Since the introduction of African swine fever into our country, the struggle has been fierce between the bureaucratic approach that only considers the reality of the raging epidemic and ignores the need to introduce seed sources, and the blind approach that only considers the need for introduction and ignores the reality of the raging epidemic. The "Animal Epidemic Prevention Law of the People's Republic of China", "Animal Quarantine Management Measures" and "Animal Husbandry Law of the People's Republic of China" have been revised successively and will come into effect on May 1, 2021, December 1, 2022, and March 1, 2023 respectively. Under this background, what should be done to introduce largescale pig farms? Based on the experience of epidemic prevention and control and the lessons learned from the introduction of breeding sources in history, the author has formed a set of methods that take into account the animal epidemic prevention requirements of both supply and demand and ensure the quality of breeding pig introduction during the technology promotion process. It has been revised and improved in accordance with the revision of laws and regulations. The revised and improved largescale pig farm introduction practices require the scientific formulation of the introduction source plan, preparation of isolation conditions in advance, and effective onsite verification by the introduction team. A threepronged approach is in place to ensure the individual quality of breeding pigs, to transport them without damage, and to report and isolate pigs in accordance with the law after landing.
