Problems solved by technology

Since the degenerated external genitalia of chickens are hidden in the anus, the difference in the external genitalia of chicks just out of the shell is very small. This method is difficult to master, requires special training, and requires high vision for the operator. It must be identified within 24 hours, otherwise the accuracy rate is not high, and it is easy to cause damage to the chicks, and the mortality rate of the chicks is high

Embodiment 1

[0019] A method for cultivating broilers with two self-sexed male and female broilers in parent generation and commercial generation, comprising the following steps:

[0020] A, get the cock whose phenotype is blue shank slow feather and does not contain the barbed feather gene as the female parent, the phenotype is the yellow shank, and the hen containing the barbed feather gene is used as the female parent, and crosses, and the obtained female Chicken is as parent generation female parent, and described parent generation female parent is the individuality of blue shank slow feather, non-horizontal spotted feather;

[0021] B. Get the cock whose phenotype is blue shank fast feather and does not contain the barbed feather gene as the terminal male parent, and cross with the parent generation female parent obtained in step A to obtain commercial generation chickens. In the commercial generation chickens, the expression Those whose phenotype is slow feathering are all roosters, ...

Embodiment 2

[0024] Because the appearance of white-feathered chicken can affect the discrimination of barbed feathers and non-barred feathers, in order to overcome the above-mentioned defects, the present embodiment is:

[0025] A method for cultivating broilers with two self-sexed male and female broilers in parent generation and commercial generation, comprising the following steps:

[0026] A. Take the rooster whose phenotype is blue-shank slow feather, does not contain horizontal-spotted feather, and does not contain recessive white-feather gene as the female male parent, and the phenotype is yellow-shank, which contains the horizontal-spotted feather gene and the recessive white-feather gene. The chicken is used as the female parent, and the hybridization is carried out, and the hen is used as the parent generation female parent in the offspring obtained, and the parent generation female parent is an individual with blue shanks and non-barred feathers;

[0027] B. Get the cock whose ...

Embodiment 3

[0030] On the basis of embodiment 2, in order to ensure that the final commercial generation chicken is a jute feather broiler, as figure 1 As shown, this embodiment is:

[0031] A method for cultivating broilers with two self-sexed male and female broilers in parent generation and commercial generation, comprising the following steps:

[0032] A. Take the rooster whose phenotype is blue-shank slow feather, does not contain horizontal-spotted feather, and does not contain recessive white-feather gene as the female male parent, and the phenotype is yellow-shank, which contains the horizontal-spotted feather gene and the recessive white-feather gene. The chicken is used as the female parent, and the hybridization is carried out, and the hen is used as the parent generation female parent in the offspring obtained, and the parent generation female parent is an individual with blue shanks and non-barred feathers;

[0033] B, get the cock whose phenotype is blue shank fast feather,...

Abstract

The invention provides a cultivating method of a parent generation and commodity generation dual auto-sexing male and female meat chicken. According to the cultivating method, three pairs of sex-linkage traits of the chicken dark color shank and the chicken light color shank, the transverse spot feather and the non-transverse spot feather, the quick feather and the slow feather are utilized to design the parent genotype and the hybridization process, in the cultivating process, whether the chicken is male or female can be directly authenticated according to the phenotype of the commodity generation and the parent generation of the chicken, the authentication accuracy of the parent generation can reach up to 99.8%, and the authentication accuracy of the commodity generation can reach up to99.5%. The cultivating method is simple and easy to operate, training special authentication personnel is not needed, a large amount of cost is saved, the authentication speed and the accuracy are high, the chickens are not injured, and the survival rate of the chickens is increased.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for breeding yellow-feathered broiler chickens with parental and commercial generations. Background technique [0002] It is of great significance to distinguish the sex of newborn chicks: it can save feed. Commercial layer farms only raise female chicks, and raising male chicks is of little value; raising male and female chicks separately is beneficial to the growth and development of female chicks, and avoids the rapid development of male chicks and the risk of food grabbing. Affecting the development of female chicks can improve the survival rate and uniformity of chicks; due to different consumption habits, some areas need male seedlings, while some places need female seedlings. [0003] The traditional method of turning the anus to distinguish between male and female is to distinguish between male and female according to the shape and color of t...
