The physicochemical properties of Shouguang chicken meat include: moisture content (%) ≥ 70.6, drying weight loss at 65 ℃ (%) ≥ 70.7, protein content (%) 20.3-29.61, calcium content (mg/kg) 5.2-6.0, and total amino acid content (g/100g) 15.6-20.6. According to Professor Li Tongshu from Shandong Agricultural University's analysis of the meat quality characteristics of Shouguang chicken, compared with medium-sized golden brown parent chickens, Shouguang chicken has outstanding advantages such as well-developed leg muscles, darker meat color, high muscle water retention and cooked meat rate, and thinner muscle fibers. Compared with AA broiler chickens, Shouguang chickens have lower muscle moisture content and higher protein content, especially in terms of intramuscular fat content, which is significantly better than AA broiler chickens. This is the main reason for the fragrant quality of Shouguang chicken meat. Overall, Shouguang chicken has a good color, high water holding capacity, suitable tenderness, and a high content of inosinic acid, a flavor component in the muscle During the Northern Wei period of the 6th century AD (1449-1597 AD), the outstanding agricultural scientist Jia Sixie wrote the book "Qi Min Yao Shu", which also recorded the poultry industry in the region.
