Problems solved by technology

[0003] Based on the public health security in the post-H7N9 era, the live poultry market is hindered, resulting in large fluctuations in the broiler market. In addition, high-quality chicken companies are difficult to cope with the plight of market fluctuations due to single products and high seed production costs, resulting in serious losses, and companies are forced to reduce production scale. , and once the market conditions get better, it is unable to replenish the flocks in time or expand the production scale, resulting in the high-quality poultry industry struggling to cope with difficulties in recent years

Embodiment 1

[0029] In this example, the plumage color is self-separated female and male hens, which are bred by the following method. The male parent is the Yunong D-series laying hen that is short, blue-legged, white in eggshell color, and yellow in appearance. , The feather color of the appearance is white, and the wing tips, tail, shoulders, and neck feathers are black. The female parent of the Yunong H line is crossed to produce a DH matching line of yellow feathers, green shanks, and powder-producing layer hens. . The cultivation mode picture is as follows figure 1 shown.

[0030] The appearance of feathers is white, and the feathers on the wing tip, tail, shoulder and neck are black for roosters, and the appearance of yellow feathers is for hens. Hens produce high-quality native eggs with powder shells. The annual egg production of the DH series is 240. Compared with the annual egg production of 150-180 eggs in the current market, the average annual egg production of the DH series...

Embodiment 2

[0032] The supporting use method of the "four lines and three uses" of the chicken matching system of this embodiment: the specific operation steps are as follows:

[0033] 1) Use a dwarf chicken with white eggshell and yellow feathers as the male parent, use normal sex, white feathers, wing tip, tail, shoulder and neck The Yunong H line with black feathers is used as the female parent to cross to produce the DH matching line, which is yellow feather, yellow shank powder shell layer hen.

[0034] 2) When the market economic benefits of laying hens are higher than or equal to the economic benefits of broiler chickens, the DH matching system in step 1) is used to produce powder-shell soil eggs;

[0035] When the market economic benefit of laying hens is lower than the market economic benefit of broiler chickens, the DH matching line in step 1) is used as the female parent, and the No. 1 paternal rooster (A) of the yellow shank medium-speed type Nanhai jute chicken (A) is used as...

Embodiment 3

[0039] The supporting use method of the "four lines and three uses" of the chicken matching system of this embodiment: the specific operation steps are as follows:

[0040] 1) The male parent is the Qingshan Yunong D-series laying hen, which is short in size, white in eggshell, and yellow in appearance. The Yunong H line with black feathers was used as the female parent for crossing to produce DH matching line with yellow feathers and green shank powder shell layer hens.

[0041] 2) When the market economic benefits of laying hens are higher than or equal to the economic benefits of broiler chickens, the DH matching system in step 1) is used to produce powder-shell soil eggs;

[0042]When the market economic benefits of laying hens are lower than the market economic benefits of broilers, the DH matching line in step 1) is used as the female parent, and the male parent of the Jinling Ma chicken (A') of the Qingshan medium-speed type is used as the male parent to carry out cross...

Abstract

The invention discloses a feather color automatic sexing hen mating strain and a hen mating strain four-strain-three-purpose mating using method, and belongs to the technical field of poultry breed production. According to the hen mating strain, a dwarf hen strain with the white eggshell and the yellow appearance feather color serves as a male parent, a normal brown laying hen strain with the white appearance feather color and the wing tips, the tail, the shoulders and the neck with the black feather color serves as a female parent, a pink shell soil specie laying hen mating strain is obtained through hybridization, the appearance feather color of a cock is mainly white, the feather color of the hen is jute feather, and automatic sexing can be carried out according to the feather colors. According to the using method, the white eggshell hen strain, the brown shell hen strain, the middle-speed yellow feather hen strain and the slow-speed yellow feather hen strain are used for breed production, a pink shell soil specie laying hen, a middle-speed type broiler hen and a low-speed type broiler hen are produced, organic fusion of the three kinds of hens is achieved, the high-quality hen four-strain-three-purpose breed production is achieved, the product diversification is achieved, the product structure can be flexibly adjusted according conditions, the risk resisting capacity is strengthened, and the economic benefit is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of poultry seed production, and in particular relates to a matching method of "four lines and three functions" of a mating line of male and female chickens with automatic feather color separation and a matching line of chickens. Background technique [0002] my country's local poultry species are rich in resources, with distinctive appearance characteristics, high-quality products, and strong stress resistance. Correspondingly, my country has formed a long-standing poultry food culture that pays equal attention to quality and appearance of "color, freshness, taste, and shape" for thousands of years. , and with the improvement of people's living standards, people's consumption concept has changed from the past quantitative type to the quality type, and people's requirements for chicken meat quality and egg quality are also getting higher and higher. Local chickens in my country have the characteristics of good...
