Embodiment 1

[0030] In the Lingyun black-bone chicken protection field of Ruidong Agriculture and Animal Husbandry Co., Ltd., Lingyun County, Guangxi, the selection and breeding of enhancing the melanin deposition of Lingyun black-bone chicken was carried out. The breeding method for enhancing the melanin deposition of Lingyun black-bone chicken includes the following steps:

[0031] Step 1. Select 60 roosters as male parents and 240 hens as female parents to establish 60 families. The selection conditions for cocks and hens are: skin melanin content heritability is within 0.15-0.22, periosteal melanin content The heritability is in the range of 0.12 to 0.19, the heritability of the melanin content in the intermuscular connective tissue is in the range of 0.17 to 0.20, and the heritability of the melanin content in the muscle fiber tissue is in the range of 0.11 to 0.15, wherein the roosters and hens are bred separately;

[0032] Step 2. Adopt the method of artificial insemination to carry ...

[0037] In the Lingyun black-bone chicken protection field of Ruidong Agriculture and Animal Husbandry Co., Ltd., Lingyun County, Guangxi, the selection and breeding of enhancing the melanin deposition of Lingyun black-bone chicken was carried out. The breeding method for enhancing the melanin deposition of Lingyun black-bone chicken includes the following steps:

[0038] Step 1. Select 60 roosters as male parents, 360 hens as female parents, and establish 60 families. The selection conditions of cocks and hens are: the heritability of skin melanin content is within the range of 0.15 to 0.22, and the black content of periosteal membrane is 0.15-0.22. The heritability of melanin content in intermuscular connective tissue is in the range of 0.12 to 0.19, the heritability of melanin content in intermuscular connective tissue is in the range of 0.17 to 0.20, and the heritability of melanin content in muscle fiber tissue is in the range of 0.11 to 0.15. Among them, roosters and hens a...

Abstract

The invention discloses a selective breeding method for enhancing melanin deposition of Lingyun black-bone chickens. The method comprises the following steps that 1, M cocks are selected as male parents, nM hens are selected as female parents, and M families are established, wherein n is an integer greater than or equal to 4 and smaller than or equal to 10; 2, an artificial insemination method isadopted for performing selective breeding of the next generation of the established families, the melanin accumulation amount of each family is counted, and the families are sorted degressively; 3, members of the families whose melanin accumulation amount is within a set range are selected, cocks and hens are selected from the members, and M new families are established; 4, steps 2 and 3 are repeated until the melanin accumulation amount of the same generation of the black-bone pheasants is higher than a set threshold value, wherein each family includes one cock and n hens, and the male parents and female parents in each family have no blood relationship. According to the method, the melanin accumulation amount of the black-bone chickens is effectively increased through selective breeding.

Description

technical field [0001] The invention relates to the field of breeding technology. More specifically, the present invention relates to a breeding method for enhancing melanin deposition in Lingyun black-bone chicken. Background technique [0002] Lingyun black-bone chicken is named after it was originally produced in Lingyun County, Guangxi. Its beak, crown, shin toe, skin, meat and internal organs are all black, and the local people commonly call it "five black-bone chicken". This variety has the characteristics of resistance to rough feeding, foraging ability, beautiful feathers, tender meat, delicious flavor, and high edible and medicinal value. It is a delicacy and nourishing product on the table. Black-bone chicken is an important characteristic medicine and food resource in my country. Compared with non-silk-bone chicken, the most notable feature is that it is rich in melanin in its body. Melanin is an important material basis for silky chicken to exert its medicinal e...
