The name "Three Yellow Chickens" was given by Zhu Yuanzhang. The so-called three-yellow chicken now does not refer to a specific breed, but refers to a general term for high-quality broiler chickens with yellow feathers. This type of chicken includes many varieties and is widely distributed. Guangdong mainly includes Sanhuang Bearded Chicken, Qingyuan Ma Chicken, Xinghua Chicken, Zhongshan Shalan Chicken, Yangshan Chicken, Wenchang Chicken, and Huaixiang Chicken. Shanghai Pudong Chicken, Zhejiang Xiaoshan Chicken, Beijing Youji, Fujian Putian Chicken, Shandong Shouguang Chicken, etc. These three-yellow chickens are popular among consumers in the domestic market and in Hong Kong, Macao, Taiwan and Southeast Asia. However, the feather colors are inconsistent, including light yellow, golden yellow, red yellow, brown yellow, brown yellow, and ephedra, hemp brown, etc.; the leg color, beak color and skin color are also different; the body shape, appearance and production performance are all different. difference. With the improvement of people's living standards and the increase of the consumer market, the demand for broiler chickens has increased. In order to meet the needs of consumers, chicken scientists and technicians have actively carried out the cultivation and breeding of three-yellow chickens based on modern genetic breeding principles and technologies. Since the introduction of Shiqi chickens from Hong Kong to Guangdong, the broiler industry has developed rapidly and the number of three-yellow chickens has increased. Currently, three-yellow chickens in Guangdong Province can be roughly divided into the following four categories according to their production performance and body size: (1) Guangdong local breeding farms, Commonly known as native breed chicken. (2) High-quality "imitation earth" yellow chickens represented by Shiqiza and Yuehuang chicken. (3) Based on the improved Shiqi hybrid chicken, its growth rate is faster and it is commonly known as the "medium-fast" three-yellow chicken. (4) "Fast and large" three-yellow chickens, represented by Yuehuang "882", are large in size, fast in growth, and have a certain bloodline with broiler chicken breeds. These three-yellow chickens not only maintain the high-quality flavor of traditional three-yellow chickens, but also increase their growth rate, feed conversion rate, meat production and egg production.
