Problems solved by technology

However, these dwarf layer chickens all have light-colored shanks (feet), and there are no reports of dark-colored shanks (such as black, cyan) dwarf broiler chickens, which can simultaneously distinguish between male and female.

Embodiment Construction

[0014] For three-series matching, see figure 1 , the seed production mode is as follows (symbols "♂" and "♀" represent cock and hen respectively):

[0015] Material:

[0016] Dark shank (feet) fast feather strain with normal weight is called A line.

[0017] The dark shank (feet) dwarf and slow-feather strain is called the B line.

[0018] Normal body weight with recessive white feathers and light-colored shanks (feet), called the C line.

[0019] step:

[0020] In the first step, use a dark shank (feet) slow-feather dwarf rooster (B line cock) to cross with a normal type recessive white feather hen (C line hen). The hen is a hen, the light-colored hen is a rooster (eliminated), and the dark-colored hen must be a dwarf slow-feather, which is the parental dwarf breeder hen (BC♀).

[0021] In the second step, the remaining parental dwarf breeder hens (BC♀) laid eggs and then crossed with dark-colored fast-feather normal cocks (A♂), and the eggs were collected for hatching. ...

Abstract

The invention relates to a seed production method for a deep-color shin(foot) undersized broiler, comprising the following steps: a deep-color shin(foot) slow feathering undersized cock is hybridized with a recessive white feathering hen with normal weight to breed a deep-color shin undersized slow feathering hen, namely the parent-breeding hen. The parent-breeding hen can, after laying eggs, be mated with the deep-color shin normal weight fast feathering cock to produce a commercial baby boiler. The commercial cock and the commercial hen have deep-color shin and normal weight, and growth speed thereof is not affected. The seed production method provided by the invention reduces breeding costs of the parent-breeding hen and simplifies breeding methods, which improves economic benefit of breeding the breeding hen without impacting the profits in breeding the commercial broiler; in addition, both the parent-breeding and the commercial broilers are capable of automatic sexing.

Description

technical field [0001] The invention relates to a seed production method for broilers Background technique [0002] In the chicken industry, the cost of feed accounts for about 80% of the cost, so reducing the cost of feed is of great significance in the farming industry. [0003] Dwarf chickens caused by the recessive sex-linked dw gene have 30%-40% lighter weight than normal weight chickens, 30% less daily feed intake, and 20% higher economic benefits than normal chickens. The egg production performance of dwarf chickens is close to that of normal chickens, without double yolk eggs, the number of qualified breeding eggs is more than that of normal chickens, and the fertilization rate and hatching rate of fertilized eggs are better than normal chickens. Normal body weight chickens are Dw gene, which is dominant to dw dwarf size, and broiler parent hens are dwarf size, which not only reduces the breeding cost of breeder chickens, but also does not carry out restricted feedi...
