Linwu Duck, one of the eight famous ducks in China, is a national geographical indication protection product. It is mainly produced in Wushui River Basin, Linwu County, one of the sources of the Pearl River. It has been a royal tribute for thousands of years and enjoys a high reputation in southern Hunan and northern Guangdong. Compared with other ducks, Linwu duck grows in farmland, streams, ponds and reservoirs, eats shrimp and plays in Shan Ye, so its meat quality is extremely delicate and delicious. The growth cycle of Linwu duck is very long, only two and a half kilograms in seventy or eighty days, while other vegetable ducks and fast-growing ducks can grow to four or five kilograms in thirty or forty days. The growth period is twice that of other duck breeds, but the weight is only half that of other duck breeds.

Linwu duck has been farmed in the wild in Shunfengshanxi and Wushui River basins at the source of the Pearl River since ancient times. It is a local traditional duck "kept in the boudoir". From 65438 to 0999, driven by Shunhua Duck Industry Company, China duck breeding and processing base was built in Linwu County. In 2006, Hunan Provincial Science and Technology Department and Finance Department launched the "Linwu Duck Industrialization Science and Technology Demonstration Base Project". The project team invested 63 1 10,000 yuan in three years to implement the three unified services of "unified seedling supply, unified epidemic prevention and unified feed" in Linwu duck breeding, completed the purification and rejuvenation of Linwu duck varieties and the promotion of standardized breeding technology of Linwu duck, and carried out the research and development of biosafety control technology for Linwu duck breeding production, as well as the deep processing of Linwu duck products and comprehensive utilization of by-products. By 2009, the county had built 43 new Linwu duck farms, expanded duck farms 1, and trained more than 8,000 farmers. The survival rate of Linwu duck culture increased from 87% in 2006 to more than 9 1%, which increased farmers' income by more than 4 million yuan from the technical level. There are 3,260 farmers engaged in Linwu duck breeding, with an average annual income of 48,000 yuan.

With the advancement of the project, the increase of Linwu duck breeding has provided sufficient raw materials for Shunhua Duck Industry Company. On the one hand, the company strengthened its production and processing capacity, expanded100000 automatic meat duck slaughtering production line, and recruited more than 350 new employees; On the other hand, we intensified product research and development, and on the original basis, we successively introduced more than 80 kinds of Chinese-style cuisines such as camellia oil duck, duck meat jiaozi, canned duck meat and bean-flavored duck, and obtained 48 patents. In 2009, Shunhua Duck Industry Company invested 1.2 1 100 million yuan to carry out expansion projects in Chenzhou and Linwu successively. After the project is completed, it can provide 5,000 jobs and drive 20,000 farmers.
