Embodiment Construction

[0067] The specific varieties involved in the present invention are for example only, and should not be interpreted as limiting the protection scope of the present invention.

[0068] The breeds used are all public breeds. Among them, the green-shell black-feathered laying hens can be purchased from Dongxiang County, Jiangxi Province, and the Jinghai Yellow Chicken can be purchased from Jiangsu Jinghai Poultry Group Co., Ltd. in Haimen, Jiangsu.

[0069] Below with Jinghai yellow chicken as precocious strain, Dongxiang green-shell hen is example to specifically set forth the method of the present invention:

[0070] Breeding steps of early-maturing strains of Jinghai yellow chicken:

[0071] (1) 6120 hens and 6218 cocks of Jinghai Yellow Chicken were selected for hatching as the basic group, and the pedigree record files were established;

[0072] (2) Determination: Male and female chickens are measured at 1, 56, 84, 112, and 300 days old, and the data are processed and selec...

Abstract

The invention relates to a rapid egg production method of laying hens with black feather and green egg shells. According to the method, firstly, bred chickens with black feather and green egg shells are used as male parents and a high-yield early maturing line is used as female parents; laying hens with the black feather and laying green-shell eggs are selected from produced chickens for reserving eggs to be used as parental generation female parents; the bred chickens with the black feather and the green egg shells are hybridized with the parental generation female parents, and produced later generations are the laying hens with the black feather and the green egg shells. The rapid egg production method has the advantages that (1) the high-yield early maturing line has early sexual maturity and a great laying quantity so that more young chickens can be provided when the high-yield early maturing line is used as the maternal line female parents; (2) commercial eggs are green-shell eggs and the nutritional value of the eggs is high; (3) the uniformity of commercial laying hens is high and the average egg weight variable coefficient of the commercial laying hens with 40 weeks age is smaller than 10%; (4) the laying quantity is improved, and the hen-housed egg production quantity of commercial laying hens with 66 weeks age is more than 200 which is improved by more than 10% in comparison with that of common green-egg-shell laying hens with green egg shells and 66 weeks age.

Description

technical field [0001] The invention relates to a seed production method for chickens, in particular to a rapid seed production method for black-feathered and green-shell layer hens. Background technique [0002] The eggshells of green-shelled eggs are natural turquoise (emerald green), and are not affected by pigments, additives and environmental changes. Green-shelled eggs are rich in various trace elements such as zinc, iodine, selenium, iron, and organic calcium content It is higher than ordinary eggs and has extremely low cholesterol. It has therapeutic and health effects on promoting children's growth and development, enhancing memory, nourishing pregnant women, and middle-aged and elderly cardiovascular diseases. Moreover, because of its unique color, green eggs are deeply loved by high-end consumers. However, the yield of green-shell hens is low, the sexual maturity is late, and the economic benefits are not ideal. At present, white-shell eggs, brown-shell eggs, an...
