Problems solved by technology

It has the advantages of rough feeding resistance, wide adaptability, stress resistance and strong disease resistance of tile-gray chicken. However, tile-gray chicken has the following disadvantages: smaller body size, longer growth cycle, and lower egg production rate. It is necessary to improve
However, the growth rate of Sichuan mountain silky is relatively slow, the survival rate is low, and its adult size is small. Therefore, when large-scale commercial production is carried out, the cost is too high, resulting in its price higher than other chicken species in the market. , has a certain restrictive effect on both the breeder and the consumer, and affects the development scale of the chicken breed

Embodiment 1

[0019] A method for cultivating gray feather silky chickens, comprising the following steps:

[0020] (1). The tile-gray chicken was established as a female line and raised in a single cage. The sperm of the tile-gray chicken was artificially collected for insemination, and the group was multiplied according to the pure feather color as the zero generation. The family breeding method is used to carry out pure line breeding to obtain purebred tile gray chickens that have passed through more than 3 generations, and select individuals with better feather color than gray varieties for breeding;

[0021] (2). Select the black-feathered Sichuan mountain black-bone chicken with pure black feather color, dark skin color and good growth performance from the original breed of Sichuan mountain silky chickens that have been purely bred for more than five generations, and the steps (1 The purebred tile-gray chicken screened in ) was used as the female parent for crossbreeding to obtain o...

Embodiment 2

[0030] The performance contrast of new variety of the present invention

[0031] Respectively select 100 "traditional Sichuan mountain silkies", "tile gray chickens" and the "gray feather silkies" obtained in embodiment 1, which are called A group, B group, and C group successively;

[0032] 2.1 Count the number of eggs laid, the weight of eggs and the number of broken eggs of the three groups of chickens within 30 days of laying eggs, and the results are shown in Table 1:

[0033] Table 1 Comparison table of egg laying conditions

[0034] Group No Number of eggs laid (pcs) Average egg weight (g / piece) Number of broken eggs (pieces) Number of broken eggs / eggs laid (%) Group A 1872 47.12 38 2.03 Group B 1785 47.96 37 2.07 Group C 2234 55.78 28 1.25

[0035] 2.2 Count the number of hatched and mature chickens in the three groups respectively, see Table 2

Abstract

The invention discloses a cultivation method of gray plumage black-bone chicken. The cultivation method includes the steps that a tile-like gray chicken and a Sichuan mountain dark-bone chicken intersect to serve as a male parent and a female parent and are hybridized to obtain A and B, A is backcrossed with the Sichuan mountain dark-bone chicken to obtain B1, B is backcrossed with the tile-like gray chicken to obtain B2, B1 and B2 intersect to serve as a male parent and a female parent and are hybridized to obtain C and D, C and D are hybridized to obtain F1, A and F1 are hybridized to obtain E, and E and F1 are hybridized to obtain F2. Compared with the traditional tile-like gray chicken, the gray plumage black-bone chicken has brighter plumage color and a purer gray plumage degree, the bodily form is increased by 15% or more, the growth period is shortened by 35% or more, the laying rate is increased by 20%, the production cost is reduced, which is beneficial for enlarging the development scale of the gray plumage black-bone chicken, the advantage of high nutrition value of the Sichuan mountain dark-bone chicken is kept, the mouthfeel, flavor and nourishing functions are good, and the effect of nourishment for vitality is achieved; compared with the traditional Sichuan mountain dark-bone chicken, the bodily form is increased by 20% or more, the growth period is shortened by 30% or more, and the survival rate is increased by 10% or more.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for breeding gray feather silkies. Background technique [0002] Tile gray chicken, also known as Anyi chicken, is characterized by gray color. It is a unique and excellent local poultry breed resource formed after long-term natural selection and artificial selection by the people of Anyi. The tile gray chicken not only has gray feathers, but also has the characteristics of "five grays" of gray skin, gray (hair) feet, gray beak and gray crown. It has the advantages of rough feeding resistance, wide adaptability, stress resistance and strong disease resistance of tile-gray chicken. However, tile-gray chicken has the following disadvantages: smaller body size, longer growth cycle, and lower egg production rate. There is a need for improvement. [0003] On the other hand, Sichuan mountain black-bone chicken is bred from Xingwen local black-bone chicken, which has a history of...
