Problems solved by technology

At present, the main feather color strains in the production of egg quail in my country are Korean quail (wild chestnut feather), Beijing white feather and Chinese yellow feather. The strains are relatively single, and there are problems of lack of genetic resources and unreasonable production group structure. There are still problems in quail breeding, such as complicated means of male and female identification, low management efficiency, etc.

Embodiment 1

[0017] The breeding method of gray feather quail strain for eggs of the present invention comprises the following steps:

[0018] (1) use the male quail of the black-feathered quail mutant to hybridize with the female quail of the yellow-feathered quail for laying eggs, and produce the first generation of hybridization, namely the F1 generation, which will produce 1 / 4 light gray-feathered quail;

[0019] (2) selfing of male and female quails with light gray feathers is selected from the F1 generation, and the second generation of offspring is the F2 generation, which will produce 1 / 4 gray feather quails in the F2 generation;

[0020] (3) Select individuals with gray feather characteristics in the F2 generation;

[0021] (4) The gray male and female quails selected in step (3) are used for cross-fixation, and through colony expansion and breeding, the gray quail strain for laying eggs can be bred after 5 to 6 generations.

[0022] Its inheritance pattern is as follows:

Embodiment 2

[0032] The breeding method of gray feather quail strain for eggs of the present invention comprises the following steps:

[0033] (1) use the male quail of the black-feathered quail mutant to hybridize with the female quail of the yellow-feathered quail for laying eggs, and produce the first generation of hybridization, namely the F1 generation, which will produce 1 / 4 light gray-feathered quail;

[0034] (2) Select the female quail with light gray feathers from the F1 generation and carry out backcrossing with its male parent to produce the first generation of backcrossing, namely the BF1 generation, which will produce 1 / 8 gray feather quails in the BF1 generation;

[0035] (3) Select individuals with gray feather characteristics from the BF1 generation;

[0036] (4) The gray male and female quails selected in step (3) are used for cross-fixation, and through colony expansion and breeding, the gray quail strain for laying eggs can be bred after 5 to 6 generations.

Embodiment 3

[0047] The breeding method of gray feather quail strain for eggs of the present invention comprises the following steps:

[0048] (1) The male quail of the black-feathered quail mutant and the female quail of the Beijing white-feathered quail are used to hybridize to produce a hybrid generation, namely the F1 generation, and the F1 generation will produce 1 / 8 light gray feather hen;

[0049] (2) Select the female quail with light gray feathers from the F1 generation and carry out backcrossing with the male quail of another black feather quail mutant to produce the backcross generation, namely the BF1 generation, which will produce 1 / 8 gray feather quails in the BF1 generation;

[0050] (3) Select individuals with gray feather characteristics from the BF1 generation;

[0051] (4) The gray male and female quails selected in step (3) are used for cross-fixation, and through colony expansion and breeding, the gray quail strain for laying eggs can be bred after 5 to 6 generations. ...

Abstract

The invention discloses a cultivation method of a gray feather quail strain for laying eggs. The gray feather quail strain can be cultivated by taking a black feather color mutant naturally generated by a Korean quail hybrid colony for laying eggs and inducing genes of Korean quails, Beijing white feather quails, yellow feather quails and other strains. The cultivation method has short time and high speed. The strain cultivated by the method maintains the advantages of high yield, strong disease resistance, easy management and the like of the Korean quails for laying eggs, overcomes the defects of photophobia and weak viability at the early stage of the Beijing white feather quails and has feather color characteristics different from quails with other feather colors. In addition, the gray feather quail for laying eggs forms a self-distinguished male and female mating strain together with the Beijing white quails, and the genders of the quails can be immediately distinguished through feather color difference when the quails are hatched, thereby simplifying the procedures for distinguishing males and females, not only saving the cost for feeding male quails at the early state, but also improving the management efficiency and having important significance on large-scale cultivation of the quails.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a method for breeding gray quail strains for eggs. Background technique [0002] Quail for eggs is a special economic poultry, which has the advantages of fast growth, early maturity, more eggs, less material consumption, and short production cycle. Quail eggs are rich in lecithin, cephalin and hormones, and have special curative effects on allergies and gastrointestinal diseases , has a special nutritional effect on the human nervous system, and the protein molecular particles of quail eggs are smaller than those of egg protein molecules, which are easier to digest and absorb. At present, the main feather color strains in the production of egg quail in my country are Korean quail (wild chestnut feather), Beijing white feather and Chinese yellow feather. The strains are relatively single, and there are problems of lack of genetic resources and unreasonable pro...
