Linwu Duck is a protected geographical indication product.

　　Linwu Duck is a unique local breed of duck from Linwu, resembling wild ducks with all lean meat and a delicious taste. It is the top duck brand in Hunan. (Chenzhou)

　　Linwu Duck is one of China’s eight famous duck breeds and a nationally protected geographical indication product. It is mainly produced in the Wushui River basin of Linwu County, one of the sources of the Pearl River. For thousands of years, it has been a tribute to the imperial court and enjoys fame across southern Hunan and northern Guangdong.

　　Compared to other ducks, Linwu Ducks grow between farmland, streams, ponds, and reservoirs, foraging for clams and shrimp and playing in the wild. As a result, their meat is extremely tender and delicious. The growth cycle of Linwu Ducks is very long—they only reach 2.5 pounds after seventy to eighty days of growth, while other meat or fast-growing ducks can weigh four to five pounds after just thirty to forty days. Their growth period is double that of other duck breeds, yet they weigh only half as much.

　　Tests conducted by the Institute of Subtropical Agriculture, Chinese Academy of Sciences, have confirmed the unique quality of Linwu Duck:

　　1. Linwu Duck is rich in all eight essential amino acids required by the human body. Compared to other duck breeds, it has a more comprehensive range and higher content of amino acids, with glutamic acid content more than twice that of other breeds:

　　2. Linwu Duck contains more than twice the amount of inosinic acid found in other duck breeds, giving its meat an exceptionally fine quality:

　　3. Unsaturated fatty acids account for 82% of the muscle fat in Linwu Duck, while saturated fatty acids make up a very small proportion. This unique fatty acid structure, similar to deep-sea fish oil, is highly beneficial to human health:

　　4. Linwu Duck contains significantly higher levels of trace elements such as calcium, zinc, and selenium compared to other duck breeds, making it a calcium-, zinc-, and selenium-rich food.

　　Hunan Linwu Duck is a well-known dual-purpose (meat and egg) local duck breed of superior quality in China. It features rapid growth, large size, high egg production, strong adaptability, high feed efficiency, tender meat, good subcutaneous fat deposition, and a delicious taste. It is one of the long-renowned specialties of Linwu County and has been a tribute through the ages.
