China's main livestock and poultry core species derived from the yield of more than 75%

Liu said that as the national team of agricultural science and technology, the "13th Five-Year" period of the Chinese Academy of Agricultural Sciences has made a series of important progress in the analysis of the genomes of pigs, beef cattle, goats, broilers, ducks, horses and other major livestock and poultry genomes, functional gene mining and research and development of key breeding technologies, breaking through a number of key breeding technologies, cultivating a number of new breeds of livestock and poultry (supporting systems), and ensuring the safety of the breeding industry.
including special market demand for Peking duck, the cultivation of "roast duck special matching system", no longer using the traditional duck filling method.
Qin Yuchang, director of the Beijing Institute of Livestock and Veterinary Research of the Chinese Academy of Agricultural Sciences, systematically introduced the progress of the "13th Five-Year" Research On livestock and poultry species industry of the Chinese Academy of Agricultural Sciences: the protection and utilization of animal and poultry species quality resources has achieved remarkable results, the construction and improvement of the network of service platforms for the protection and sharing of animal and poultry species resources, and the digital and information sharing of 777 livestock and poultry species resources; Frozen embryos and sorocytes have long preserved more than 300 local animal and poultry species species quality resources, greatly improved the diversity of the preservation of animal and poultry species resources in China, carried out basic character identification of collected resources, screened out a number of high-yielding, high-quality and highly resistant species resources, and supported the cultivation of a series of important new breeds of livestock and poultry.
discovered a number of functional genes with significant breeding value of pigs, beef cattle, goats, broilers, ducks, horses and other major livestock and poultry, and constructed an efficient molecular breeding technology system.
has cultivated a number of new breeds of livestock and poultry (supporting systems) to ensure the safety of the breeding industry.
To Beijing roast duck as an example, the Chinese Academy of Agricultural Sciences Beijing Pastoral Medical Institute researcher, waterfowl breeding and nutrition innovation team chief scientist Zhou Zhengkui introduced that roast duck this special cooking method was prevalent in the Ming and Qing period, but it has a high fat content of ducks (body fat is not up to standard, roasted meat dry, hard);
"Roast duck special supporting system" breeding project has made two disruptive changes, one is to excavate the Beijing duck fat deposition gene, to cultivate a new supporting breed suitable for roast duck, and the other is to develop a special formula feed, so that the "fill duck" breeding method is gone forever.
