Problems solved by technology

At present, the method of turning the anus is mostly used to identify the sex of chickens. The disadvantages of this method are mainly infectiousness, cross-infection of diseases, greater stress to animals, and high labor costs. Therefore, it is convenient to distinguish the sex of chicks by feather color An effective method of gender identification

Embodiment Construction

[0032] The implementation of the present invention will be described in detail below with examples, so as to fully understand and implement the implementation process of how the present invention uses technical means to solve technical problems and achieve technical effects.

[0033] The invention provides a method for producing green-shell laying hens with deep and light shell colors in matching combination, such as figure 1 shown, including the following steps:

[0034] (1) The breeding materials are 300 chickens of the JY series (second generation) of the old courtyard black chicken and the LK series (the third generation) of the green-shell layer raised by the poultry breeding farm of Sichuan Agricultural University; 60 strong old chickens were screened out. Yard black chicken JY line roosters are used for the detection of green shell genes.

[0035](2) After collecting blood from 60 healthy and disease-free old hospital black chicken JY line roosters, take 25 μL of blood...

Abstract

The invention discloses a method for combination production of green-shelled chickens with dark and light shell colors. The method comprises the following steps that on the basis of direction seed introduction or molecular seed selection, Jiuyuan black chicken (JY), Dongxiang green-shelled chicken (LK) and Luhua chicken (LH) basic groups are constructed, the 300-day old egg yield is increased through family selection, the combination mode is determined through reciprocal cross experiments, commodity generations can product green-shelled eggs of different green degrees, and auto-sexing of chicken can be achieved. The breeding method can be popularized and used for other variety selection of green-shelled chicken; the chicken hybridized combination JK which achieves the five blacks (black feather, black skin, black crown, black shin and black meat) appearance features and the total good production performance and is capable of producing green-shelled eggs is obtained; the LK line is adopted as the female parent to be hyrbided with the JY line to obtain the chicken hybridization combination LL which achieves auto-sexing through chick feather color and the excellent total production performance and is capable of producing atrovirens-shelled eggs. The combination method and technology reach the advanced level in China.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for matching and combining green-shell laying hens with dark and light shell colors. Background technique [0002] The eggs of the unique green-shell layer breeds in my country have the characteristics of low cholesterol and low fat, and are rich in various trace elements such as selenium, iodine, iron and zinc, and consumers often have a preference for eggs of a certain color. In line with market demand, the market prospect is broad. At present, there are few mature varieties of green-shell hens, and the stock is low, so the supply exceeds demand; and green-shell eggs have higher economic value than ordinary eggs. Therefore, it is necessary to do in-depth research and development work on the matching breeding of green-shell layer hens. [0003] The green shell trait is controlled by the No. 1 autosomal dominant green shell gene (Oocyan, O), which i...
