The native chicken marking and mating technique is belongs to the field of domestic bird genetic technique. The Beijing oil chichen has golden genetic genes, phoenix head, hair feet and five toes. Take it as the paternal to cross with the high layer hen which has silver genes, and the main strain is the import high-yield mating female line hen(such as roman egg chicken, halen egg chicken and yisa egg chicken). The hens of the filial generation are having golden feathers, while the cocks are having efflorescence feathers, so the day-old chick's sex can be distinguished by the feather.

It improves the egg-laying property substantially, reduces the cost of production, and has great economic benefit and social benefit.
Description
technical field [0001] The invention relates to a matching technology for high-quality laying hens in poultry production, and belongs to the technical field of poultry genetics. Background technique [0002] Soil eggs have been favored in my country's vegetable market for a long time, and the sales volume has increased year by year, with an annual increase rate of more than 30%. A large number of studies have proved that the egg yolk of soil-raised eggs is large, rich in vitamins and various amino acids, especially the content of lecithin, which is beneficial to human health, is higher than that of ordinary eggs. Therefore, it is very popular among consumers, and the price remains high, and the market has been in a situation of short supply. Soil eggs are produced by local chickens, and their egg production rate is low. For example, Beijing oil chicken is a world-famous chicken breed, which is widely used in production due to its unique high quality. However, the number of...
