Embodiment 1

[0023] A method for breeding yellow-feathered broiler chickens, selecting fast-growing yellow-feathered broiler breeds as male flocks, and dwarf yellow-feather broiler breeds as female-line flocks, with 4,000 hens in female-line flocks and 600 hens in paternal-line flocks , the second-line cock is 12% of the number of hens, and it is cultivated according to the following steps:

[0024] The first step, 0-6 weeks old brooding period:

[0025] Raised in cages at 28°C, the protein content in the feed is 18%, and the energy is 2000 kcal / kg;

[0026] 0 days old: Eliminate chicks with body weight below average, with variegated feathers, or with cyan foot skin;

[0027] 1 day old: Inject 1.5X Marek liquid vaccine subcutaneously in the neck;

[0028] 3-5 days of age: apply 2X new two-way freeze-dried vaccine by eye drops or nasal drops;

[0029] 7-8 days old: apply 1X Fajilsen freeze-dried vaccine in the form of instillation;

[0030] Age of 10 days: Eliminate individuals who have...

Abstract

The invention relates to a yellow-feathered broiler breeding method which is characterized in that the second generation is bred in the following steps that: 0-day: chicks which are lighter than the average weight, have variegated feathers or blue foot skin are eliminated; 10-day: individuals which do not have tail, and have variegated feathers or blue foot skin are eliminated; 10-week: individuals which are lighter than the average weight, have variegated feathers or blue foot skin are eliminated; and 18-week: cocks which have the crown height lower than 3cm, chest expansion angle smaller than 60 degrees, tibial diameter smaller than 1.2cm or blue foot skin, and hens which have pale face, lack energy, and have the tibial diameter smaller than 1cm and blue foot skin or bend toes are eliminated. The yellow-feathered broiler breeding method can make the chicken performance progress for generations and not degenerate for a long time.

Description

technical field [0001] The invention relates to a method for breeding yellow-feathered broiler chickens, which is used for cultivating and improving new matching chickens, and belongs to the technical field of animal husbandry breeding of livestock and poultry genetics. Background technique [0002] Modern poultry breeding technology, especially chicken breeding, is to use hybrid advantage to continuously select to improve the production performance and body appearance of chicken breeds.
