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 invention relates to the field of genetic breeding of domestic fowls and particularly relates to a selective breeding method for high-uniformity slaughter type high-quality spotted-brown chickens.The method comprises the steps: establishing three specialized lines, wherein a line A is a rapid-big spotted-brown chicken assorted terminal paternal line, is a normal type spotted chicken and is medium or relatively high in growth speed; a line B is a DW-linked-gene spotted-brown chicken pure line, is a dwarf type spotted chicken, is medium or relatively low in growth speed and contains an ultrarapid-big AA chicken blood line; and a line C is a normal type brown chicken and is medium or relatively high in growth speed; producing a parent-generation BC line by taking a cultured line C as a first female parent and taking a cultured line B as a first male parent; and producing commodity chickens ABC by taking a cultured line AA as a terminal male parent and taking selected and reserved hens of the parent-generation BC line as a terminal female parent. Through the method, the high-quality chickens, which are suitable for being subjected to factory slaughter processing and are obvious inslaughter property advantages, can be cultured; and through a mode of matching of three lines, a new variety of high-uniformity slaughter type high-quality cold-fresh chickens, which are stable in genetics, meet requirements of a live chicken market and can be directly applied to product, is bred.

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. ...
