Description

Technical Field

[0001] The present application relates to the technical field of poultry breeding, and in particular to a breeding method for Fengxiang Ma chicken. Background Art

[0002] Southern my country, especially the Guangdong and Guangxi regions, values ​​the color, aroma, and flavor of chicken. Thousands of years of culinary tradition have shaped a unique culture of chicken consumption. Currently, the main broiler breeds produced in China are fast-growing broilers, medium-growing broilers, and premium-quality broilers. Fast-growing broilers are primarily imported white-feathered broilers, while medium-growing and premium-quality broilers are primarily high-quality breeds developed by Chinese broiler breeding companies through crossbreeding of new and local varieties.

[0003] Guangxi boasts a long history of breeding high-quality local chicken breeds. Through both natural and artificial selection, a diverse and distinctive breed of chicken has emerged, forming a vital gene pool for high-quality local chickens in my country. Currently, three-yellow chickens and skewered chickens dominate the domestic market, with an annual commercial supply exceeding one billion. Changing market demands have led to higher quality skewered chickens. The current plethora of skewered and yellow chicken varieties creates intense market competition, making selection difficult for customers. Standardized cuisines lack universal applicability, and chicken ingredients, inaccurately targeted by regional and consumer preferences, lead to waste. Summary of the Invention

[0004] In order to solve the above technical problems, the present application provides a method for breeding Fengxiang Ma chicken, which comprises:

[0005] The F1 generation was obtained by hybridization using Guangxi Longsheng Feng chicken as male parent and Guangdong Qingyuan Ma chicken as female parent.

[0012] The chicken feet of the commercial generation Fengxiang Ma chicken chicks are provided in a combination of three or more different foot colors: green feet, mung bean feet and yellow feet;

[0013] The feather color of all the commercial roosters is single-color dark red hemp feathers; all the hens are a mixture of double-color hemp feathers and rice flower feathers when they are paired together, and are pure color hemp feathers and pure color rice flower feathers when they are paired together.

[0014] Optionally, the paternal parents of the Fengxiang Ma chicken lines A and B, the paternal parents of the lines C and D, the paternal parents of the lines E and F, and the female parents of the first generation of the Fengxiang Ma chicken are subjected to directional cross-hybridization to obtain a plurality of single-matched and double-matched Fengxiang Ma chicken commercial chicks, including:

[0015] Optionally, the male parent of the Fengxiang Ma chicken A line is hybridized with the female parent of the Fengxiang Ma chicken generation B1 to obtain a new breed of Fengxiang Ma chicken with full anesthesia feathers in both male and female Qingjiao lines;

[0016] Optionally, the Fengxiang Ma Chicken B-line male parent and the Fengxiang Ma Chicken A1 female parent of the second generation are hybridized to obtain a new breed of Fengxiang Ma Chicken with deep red hemp feathers for the Qingjiao roosters and pure rice-colored feathers for the hens.

[0017] The roosters in the two green-footed matching Fengxiang Ma chicken chicks have the same single feather color of dark red hemp feathers, while the hens have hemp feathers and rice flower feathers respectively. The two matching sets can be freely combined to obtain a new breed of green-footed double-matching Fengxiang Ma chicken.

[0018] Optionally, the male parent of the Fengxiang Ma chicken C line and the female parent of the second generation D1 of the Fengxiang Ma chicken are hybridized to obtain a new breed of Fengxiang Ma chicken with full anesthesia feathers for both males and females of the mung bean foot line.

[0019] Optionally, the Fengxiang Ma Chicken D-line male parent and the Fengxiang Ma Chicken first generation C1 female parent are hybridized to obtain a new breed of Fengxiang Ma Chicken in which the males have mung bean foot feathers and the females have rice flower feathers.

[0020] The breeding method of the mung bean foot series Fengxiang hemp chicken is characterized in that the roosters in the two mung bean foot series Fengxiang hemp chicken chicks have the same single feather color of dark red hemp feathers, and the hens have hemp feathers and rice flower feathers. The two sets can be freely combined to obtain a new variety of mung bean foot series double-matching Fengxiang hemp chicken.

[0021] Optionally, one of the two paired combinations of the AB series, CD series, and EF series has the sex-linked golden feather gene s, and the other has the silver feather gene S.

[0022] It can be seen from the above technical solutions that this application has the following advantages:

[0023] The Fengxiang Ma chicken bred with this technology has its own characteristics and varieties.

[0024] The method provided by the present application solves the problem of regional differences in foot color selection between yellow-footed and green-footed chickens, and obtains multiple single-matched and double-matched new varieties of Fengxiang hemp chicken commercial chicks, wherein the chicken foot colors of the Fengxiang hemp chicken commercial chicks are matched with more than three different foot colors, namely green feet, mung bean feet and yellow feet. Through this method, commercial male and female chickens can be customized in foot color and proportion of different feather colors according to customer market demand, and are more adaptable to market demand. In addition, they grow faster than Longsheng Feng chickens, have better precocity, more consistent crest formation, well-developed breast and leg muscles, and have greatly improved skin and meat color compared to Longsheng Feng chickens. The chicken flavor and nutrition are similar to those of the original Qingyuan chicken, while maintaining some of the appearance characteristics of Longsheng Feng chickens and Qingyuan chickens. Some individuals have foot hair, and the mung bean-footed Fengxiang hemp chickens have green feet and yellow skin after slaughter. This variety is more extensive and versatile in terms of utilization value in the broiler food market. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 This is a schematic diagram of the ancestral stock cultivation stages in this application;

[0026] Figure 2 This is the family and product generation stage in this application. DETAILED DESCRIPTION

[0027] The method provided in this application is used to breed Fengxiang Ma chicken. The following examples describe the method in detail:

[0028] The cultivation process in this application can be divided into the ancestral stock cultivation stage and the family synthesis stage. The cultivation process is described below:

[0029] The breeding process needs to be divided into two parts, the grandparent stock breeding stage and the family synthesis stage.

[0030] First, the genetic symbols involved in this application are explained:

[0031] ♀——Maternal parent

[0032] ♂——male parent

[0033] ×——Hybridization

[0034] k——Fast Feather Gene

[0035] S——Silver Feather Gene

[0036] s——Golden Feather Gene

[0037] Foot color - shin color

[0038] Rice Flower Feathers - The rice flower feathers in this application are similar in color to the feathers of Guangdong Rice Flower Chicken, Colorful Phoenix Chicken, and Longsheng Phoenix Chicken hens. The color is slightly darker and slightly more hempy than the back feathers of Guangdong Rice Flower Chicken and Colorful Phoenix Chicken hens, and the chest hair is red. The breast hair of Rice Flower Chicken and Colorful Phoenix Chicken is mostly white, slightly lighter than the colorful feathers of Longsheng Phoenix Chicken. The chest hair of the colorful feather chickens in Longsheng Phoenix Chicken is mostly black.

[0039] Mung bean feet - In this application, mung bean feet are also called mung bean shanks. The color of the shanks is between light green and dark yellow. The outer shanks are the color of mung beans. After slaughter, the inner shanks are the color of the green shanks. The skin is slightly yellower than that of the green shank chicken. This is defined as mung bean feet in this application.

[0040] Since the silver feather (deep red hemp feather) and golden feather (rice flower feather) genes are both located on the sex chromosomes, and the silver feather (S) is dominant to the golden feather (s), that is, using the principle of sex-linked inheritance, the female parent is selected from the strain with the dominant silver gene (S), and the male parent is selected from the strain with the recessive golden gene (s). After the two are hybridized, the first generation of male chicks have the silver feather gene (deep red hemp feather) and the female chicks have the golden feather gene (rice flower feather). As soon as the chicks hatch, the gender can be identified by the color of the feathers, which is clear at a glance and more convenient than using fast and slow feathers to identify the gender.
