Embodiment 1

[0046] The present invention is a method for improving the laying rate of Guizhou local chicken breeds by adopting the recessive white feather new strain bred by the above method, the implementation steps of the method can be found in figure 2 ,which is:

[0047] (1) F 1 Breeding of generation chickens: Recessive white feather chickens are selected as the male parent, which is characterized by stable genetic performance, obvious breed characteristics, neat appearance, good growth performance, and a 7-month-old rooster weighing 1.2 Kg.

[0048] Medium-sized high-yield laying hens are used as female parents (generally produce brown-shell eggs), which are characterized by relatively pure genetic foundation and good egg production performance. At 72 weeks old, the egg production can reach more than 270 eggs, and the average egg weight is more than 55 g.

[0049] Using artificial insemination technology, the above-mentioned parents were paired with two lines to pr...

Embodiment 2

[0055] The present invention is a method for improving the meat quality and flavor of foreign chicken breeds by adopting the new recessive white feather strain bred by the above method, and the implementation steps of the method can be found in image 3 ,which is:

[0056] (1) Recessive white-feathered chickens are selected as the male parent, which is characterized by stable genetic performance, obvious breed characteristics, neat appearance, good growth performance, and a 7-month-old rooster with a weight of 1.2 Kg.

[0057] The fast-growing broiler chicken is used as the female parent, which is characterized by a relatively pure genetic basis and a fast growth rate, but the meat quality is poor and the taste is rough.

[0058] (2) Using artificial insemination technology, the above-mentioned parents were paired with the second line to produce F 1 Substitute chicken.

[0059] bred F 1 The generation chicken contains 50% of recessive white feather chick...

Abstract

The invention discloses a cultivation method and application of a recessive white feather new strain of Xiaoxiang chicken in southeast of Guizhou province. The method includes the following steps: (1) selfcrossing breeding is carried out on white feather chicken separated from the Xiaoxiang chicken in southeast of Guizhou province to obtain a F1 generation; (2) according to molecule marker-assisted selection, individuals of recessive homozygosis allelic genotypes of II are screened from the F1 generation; (3) test mating between a sanhuang chicken pure line or other colored feather chicken pure lines and the F1 is carried out, the dominance white feather individual and the colored feather individual which are separated from the F1 are rejected, recessive pure individual cock and hen are bred in cooperation with detection results in the step (2), and then self-reproducing is carried out to obtain B; according to the method in the step (3), repeated test mating and breeding are carried out on W in the step (3), and the separated dominance white feather individual and the separated colored feather individual are rejected continuously; selfcrossing breeding and group extending are carried out on the selected dominance white feather individual, a family is formed, and the recessive white feather new strain is cultivated.

Description

technical field [0001] The invention relates to a breeding method and application of a new recessive white feather strain of Qiandongnan small fragrant chicken, which belongs to the field of breeding technology. Background technique [0002] Qiandongnan small fragrant chicken is one of the excellent local poultry breed resources in Guizhou. It is mainly produced in Congjiang, Rongjiang and Liping counties and adjacent areas of Guizhou Province. It is famous for its "smallness, earthiness and fragrance". In the process of breed selection and germplasm innovation for many years, white feather individuals were found, accounting for about 3-5% of the total chicken flock. The breed characteristics of this group are obvious, the whole body is covered with pure white feathers, most of them are flat head and single crown, and the beak and shank are black Brown, with white or black flesh, a few individuals have shin feathers, commonly known as hakama chicken; this chicken has the adv...
