Embodiment 1

[0013] The breeding method of black feather powder-shell hens is cultivated through the following steps:

[0014] (1) Select the A-line cock of the great-grandfather of the brown-shell hen as the male parent, and extract the semen manually;

[0015] (2) Select the pure line hen of imperial concubine chicken as female parent, and carry out artificial insemination;

[0016] (3) Collect the breeding eggs produced by the imperial concubine chicken hen after 2 days of fertilization, and hatch;

[0017] (4) The hatched male and female chicks are all black feathers, and the eggs laid by the female chicks are powder-shelled, that is, they are bred into black-feathered powder-shell hens.

Embodiment 2

[0019] The breeding method of black feather powder-shell hens is cultivated through the following steps:

[0020] (1) Select the B-line cock of the great-grandfather of brown-shell hens as the male parent, and extract the semen manually;

[0021] (2) Select the pure line hen of imperial concubine chicken as female parent, and carry out artificial insemination;

[0022] (3) Collect the breeding eggs produced by the imperial concubine chicken hen after 2 days of fertilization, and hatch;

[0023] (4) The hatched male and female chicks are all black feathers, and the eggs laid by the female chicks are powder-shelled, that is, they are bred into black-feathered powder-shell hens.

Embodiment 3

[0025] The breeding method of black feather powder-shell hens is cultivated through the following steps:

[0026] (1) Select the A-line cock of the brown-shell hen progenitor as the male parent, and extract the semen artificially;

[0027] (2) Select the pure line hen of imperial concubine chicken as female parent, and carry out artificial insemination;

[0028] (3) Collect the breeding eggs produced by the imperial concubine chicken hen after 2 days of fertilization, and hatch;

[0029] (4) The hatched male and female chicks are all black feathers, and the eggs laid by the female chicks are powder-shelled, that is, they are bred into black-feathered powder-shell hens.

Abstract

The invention discloses a cultivation method of black-feather pink-egg layer chickens. The cultivation method comprises the following steps of: (1) selecting a brown-egg layer chicken great-grandparent A series cock, a brown-egg layer chicken great-grandparent B series cock, a brown-egg layer chicken grandparent A series cock, a brown-egg layer chicken grandparent B series cock or a brown-egg layer chicken parent AB series cock as male parents and extracting seminal fluid by using a manual mode; (2) selecting a highest ranking imperial concubine hen as a female parent to carry out artificial fertilization; (3) collecting hatching eggs laid by the highest ranking imperial concubine hen in two days after the fertilization and hatching the eggs; and (4) obtaining hatched hens namely the black-feather pink-egg layer chickens. The body shape, the weight and the appearance of the cultivated black-feather pink-egg layer chicken are similar to that of a native chicken, the color of the feathers of the cultivated layer chicken is black, and laid eggs have pink shells. The egg laying property of the cultivated layer chicken is good, the annual egg yield can reach 210-230, and the later egg weight is about 50g. The black-feather pink-egg layer chickens can be raised in cages or stocking, have high spent chicken price and are suitable for large-scale cultivation.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for cultivating black-feather powder-shell laying hens. Background technique [0002] China's traditional food culture has a very important influence on the food structure. Food consumption not only pays attention to nutrition and flavor, but also has high requirements on the appearance of food. Eggs are one of the important animal protein sources for people’s daily consumption. With the development of the economy and the improvement of living conditions, consumers’ requirements for the quality of eggs are also gradually increasing. Especially in recent years, the market demand for native eggs has continued to expand. Profits also attract more farmers. However, due to the poor egg-laying performance of native chickens, in general, the maximum number of eggs laid per year is no more than 180, which affects the industrialization of native chickens. ...
