Scope

Main technical content: Jingyuan chickens are a national-level protected breed of livestock and poultry genetic resources, and one of the five regional-level protected breeds of livestock and poultry genetic resources in the autonomous region. Jingyuan chickens, formerly known as Gulin chickens or Jingning chickens, originate from Gulin City in Ningxia and Jingning County in Gansu Province, with a wide distribution area. They can be found in all districts and counties of Gulin City, with the main production areas centered on Jiaocha, Luowan, Wangwan, Xiaocha, Fengzhuang Town in Pengyang County, north of the eastern foothills of the Loping Mountains, and Hechuan, Guandong, Zhaike Towns in Dongzhou District. They are also distributed in nearby production areas such as Haiyuan, Xiji, Longde, and Jingyuan. Their commercial name is "Chaona Chicken", and the products have been certified as green products by the National Agricultural Products Quality and Safety Center after being registered as geographical indication products by the Ministry of Agriculture and protected as geographical indication products by the State Administration for Industry and Commerce. Jingyuan chickens are a dual-purpose local breed, characterized by a tall stature, robust bones, deep chest and back, wide and full hindquarters, adaptability to coarse feed and grazing, strong resilience, and high-quality meat with high nutritional value. However, from the perspective of resource protection and long-term development, Jingyuan chickens, as an excellent local chicken breed, have not had corresponding breed standards. There are unclear breed performance indicators, unclear genetic characteristics, and declining breed purity and production performance. Through comprehensive, reliable, and systematic resource surveys and production performance assessments, this study has identified the breed characteristics of Jingyuan chickens, which is of great significance for accelerating the protection of their
