Problems solved by technology

What is even more rare is that white feather chickens have low hugability, and the average annual egg production is 40-50% higher than that of colored feather chickens of the same breed. The disadvantages are small size, slow growth, low egg production, and small egg weight.

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 produce F 1 Substi...

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 chicken blood, which can ...

Abstract

The invention discloses a cultivation method and application of a new recessive white-feather strain of Qiandongnan Xiaoxiang chicken. The method is carried out according to the following steps: (1) F1 generation is self-bred with white-feathered chicken isolated from Qiandongnan Xiaoxiang chicken; (2) According to molecular marker-assisted selection, select individuals with the recessive homozygous allele of ii from the F1 generation; (3) Testcross the F1 with the Sanhuang chicken pure line or other colored feather chicken pure lines, and eliminate the F1 The dominant white-feather individuals and colored-feather individuals separated from , combined with the detection results of step (2) to select recessive homozygous individual male and female chickens, and then self-propagation to produce B; (4) according to the method of step (3) , carry out repeated test crossing and breeding for W in step (3), and continuously eliminate and isolate dominant white feather individuals and colored feather individuals; carry out self-propagation and expansion of the selected recessive white feather individuals, form families, and breed recessive white feather individuals. A new strain of white feathers.

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...
