AI Technical Summary
The Puan Panjiang Black-boned Chicken has a slow growth rate, long breeding cycle, and low egg production, resulting in high breeding costs, serious loss of germplasm resources, and a lack of systematic protection mechanisms.
Using a three-line breeding method to improve the quality of Puan Panjiang black-bone chickens, the bloodlines of Ma Yu black-bone chickens and Zhuxiang chickens were introduced through hybridization to form a matching combination of MW×ZX×PA. This method was used to breed high-quality Puan Panjiang black-bone chickens, which retain the appearance characteristics of black feathers, black skin, black shanks, black combs, and black meat, and improve their growth rate and egg production performance.
The high-quality Puan Panjiang Black-boned Chicken grows quickly, reaches market age early, lays high eggs, and has good meat performance, meeting consumers' preference for "five black chickens." It can be used for both meat and eggs, significantly improving growth rate and egg production, thus meeting market demand.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of poultry breeding, and in particular to a method for producing seeds of three-line matching high-quality Pu'an Panjiang black-bone chickens. Background Art
[0002] Local chickens have the characteristics of excellent meat and egg quality, but have shortcomings such as slow growth rate, low production performance, and long breeding cycle. Therefore, on the basis of retaining the appearance characteristics and market weight of local chicken breeds, improving their growth rate, shortening their market age, and increasing egg production can effectively reduce the overall breeding cost. Increasing breeding batches is one of the cost-reduction and efficiency-increasing measures to cope with the high cost of feed raw materials.
[0003] The Pu'an Panjiang black-bone chicken is named after the Beipanjiang River basin in Pu'an County, Qianxinan Prefecture, Guizhou Province, where it is mainly produced. It is also known as the Pu'an Niujiaoshan black-bone chicken and the Pu'an black-gold chicken. After a long period of natural and artificial selection, it has gradually become a special black-bone chicken variety that can be used for both meat and medicine and is resistant to roughage. It has the characteristics of black feathers, black shanks, black skin, black meat, and black bones, as well as strong resistance to adversity and delicious meat and eggs. It has become the main promoted variety of the local ecological poultry industry. However, the current development and utilization of the Pu'an Panjiang black-bone chicken is still very low, and the loss of germplasm resources and the lack of a systematic protection mechanism are becoming increasingly serious. There are problems such as slow growth, long breeding cycle, and low egg production, which seriously restrict the high-quality development of the industry. Therefore, it is very necessary to carry out germplasm innovation on the local resource Pu'an Panjiang black-bone chicken.
[0004] The Bamboo Chicken, named after its origins in Chishui City, Zunyi City, Guizhou Province, known as the "Hometown of Nanzhu," is a local breed used for both meat and eggs. Due to the local preference for black-bone individuals, they were intentionally selected, resulting in a black appearance with black hair, skin, meat, bones, beak, comb, and toes. They exhibit rapid early growth, strong resistance to stress, and tender meat. They also boast high egg-laying performance, producing light brown eggs, with some populations producing green-shelled eggs. They are a highly valuable and versatile breeding material, but their current development and utilization remains limited. The Black-Feathered Chicken, with its excellent meat and egg-laying qualities, grows quickly and weighs heavily. Characterized by red hemp feathers, black bones, black skin, and black shanks, they can be used to improve local breeds, such as slow growth and low weight.
[0005] Therefore, by utilizing the advantages of the above materials, further hybridization and improvement of Pu'an Panjiang black chicken can be carried out. On the basis of retaining its appearance characteristics and market weight, its growth rate can be improved, its market age can be shortened, and its egg production can be increased, so as to cultivate high-quality Pu'an Panjiang black chicken that can meet the needs of the southwest and south China regions.
