Embodiment 1

[0028] A method for breeding high-quality slaughtered ephedra chickens with high uniformity, characterized in that the breeding method is:

[0029] In step (1), three specialized strains are established: the A line is the terminal male line of the fast ephedra chicken, the normal type hemp feather chicken, and the growth rate is medium to fast; the B line is the pure line of the ephedra chicken containing the DW sex-linked gene, Dwarf hemp-feathered chicken with medium-to-slow growth rate, containing bloodline of extra-fast large AA chicken; C line is normal yellow-feathered chicken with medium-to-fast growth rate;

[0030] Step (2), using the cultivated C line as the first female parent and the cultivated B line as the first male parent to produce the parent generation BC line;

[0031] In step (3), the A line cultivated in step (1) is used as the terminal male parent, and the hen of the parent generation BC line selected in step (2) is used as the terminal female parent to p...

Embodiment 2

[0043] A method for breeding high-quality slaughtered ephedra chickens with high uniformity, characterized in that the breeding method is:

[0044] In step (1), three specialized strains are established: the A line is the terminal male line of the fast ephedra chicken, the normal type hemp feather chicken, and the growth rate is medium to fast; the B line is the pure line of the ephedra chicken containing the DW sex-linked gene, Dwarf hemp-feathered chicken with medium-to-slow growth rate, containing bloodline of extra-fast large AA chicken; C line is normal yellow-feathered chicken with medium-to-fast growth rate;

[0045] Step (2), using the cultivated C line as the first female parent and the cultivated B line as the first male parent to produce the parent generation BC line;

[0046] In step (3), the A line cultivated in step (1) is used as the terminal male parent, and the hen of the parent generation BC line selected in step (2) is used as the terminal female parent to p...

Embodiment 3

[0057] A method for breeding high-quality slaughtered ephedra chickens with high uniformity, characterized in that the breeding method is:

[0058] In step (1), three specialized strains are established: the A line is the terminal male line of the fast ephedra chicken, the normal type hemp feather chicken, and the growth rate is medium to fast; the B line is the pure line of the ephedra chicken containing the DW sex-linked gene, Dwarf hemp-feathered chicken with medium-to-slow growth rate, containing bloodline of extra-fast large AA chicken; C line is normal yellow-feathered chicken with medium-to-fast growth rate;

[0059] Step (2), using the cultivated C line as the first female parent and the cultivated B line as the first male parent to produce the parent generation BC line;

[0060] In step (3), the A line cultivated in step (1) is used as the terminal male parent, and the hen of the parent generation BC line selected in step (2) is used as the terminal female parent to p...

Abstract

The present invention relates to the field of poultry genetics and breeding, in particular to a method for breeding high-quality ephedra chickens with high uniformity of slaughter, including: establishing three specialized strains: the A line is the terminal male line of the fast ephedra chicken, and the normal type ephedra chicken Chicken, the growth speed is medium to fast; the B line is the pure line of ephedra chicken containing the DW sex-linked gene, the dwarf hemp feather chicken, the growth speed is medium to slow, and contains the blood of the super fast large AA chicken; the C line is the normal yellow feather chicken, the growth The speed is medium to fast; the cultivated C line is used as the first female parent, the cultivated B line is used as the first male parent, and the parent generation BC line is produced; the cultivated A line is used as the terminal male parent, and the parent generation is selected and retained The hen of BC line is used as the terminal female parent to produce commercial chicken ABC. Through the present invention, a high-quality chicken that is suitable for industrial slaughtering and processing and has obvious advantages in slaughtering traits can be bred, and a high-uniform slaughter-type high-quality cold chicken that is genetically stable, meets the market demand of live chickens, and can be directly used in production can be bred through a three-line matching model. New breed of fresh chicken.

Description

technical field [0001] The invention relates to the field of poultry genetics and breeding, in particular to a breeding method for high-uniform slaughter type high-quality ephedra chickens. Background technique [0002] Due to China's special eating habits, the sales of high-quality chickens will still be dominated by live chickens in the next few years, but the sales of chilled chickens will be driven by the general trend and become an inevitable development trend. In Guangdong, Zhejiang and other provinces and cities, restrictive measures such as no live poultry sales in cities above the municipal level have been implemented, and will gradually be expanded to other regions. Slaughtering and listing will gradually replace high-quality live chickens for listing. Faced with the urgent situation that governments at all levels are gradually closing down the live poultry market, the yellow-feather broiler industry has entered a critical period of transformation and upgrading.
