Problems solved by technology

Using Jiuyuan black chickens and Dongxiang green-shell hens as a single breed to produce green-shell hens respectively has the disadvantages of low green-shell egg rate and poor performance of eliminated chickens, and the provenance cannot be controlled
In addition, although the egg production of reed chicken is relatively high, it cannot produce green shell eggs.

Embodiment Construction

[0030] 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.

[0031] The present invention provides a kind of three-series matching black-feathered black-skinned green-shell laying hen seed production method, such as figure 1 shown, including the following steps:

[0032] (1) Construct the basic groups of Jiuyuan black chickens, Dongxiang green-shell hens and reed hens: the JY line of Jiuyuan black chickens, the LK line of Dongxiang green-shell hens and the LH line of Hungarian Heikang layer hens are used as the zero generation, Single-cage rearing, artificial insemination, selection and formation of a generation core group; carry out group subculture, according to the 300-day-old body weight of the rooster (body weight is 2.8kg) and the 300-day-old egg production ...

Abstract

The invention discloses a method for producing three-line matching black-feather black-skin green-shell chickens. The method includes the following steps: constructing a foundation group of a Jiuyuanblack JY line, a Dongxiang green-shell chicken LK line and a Luhua chicken LH line by direct introduction; carrying out group systematic breeding, and establishing multiple generations according to the egg yield of 300-day-weight cocks and 300-day-weight hens; adopting a pure breeding method to implement individual selection and family selection for three pure lines; determining a matching combination JY*(LK*LH) to produce high-quality compatible-type black-feather black-skin green-shell chickens with black appearance features and good overall production performance. The three-line matching combination of black-feather black-skin green-shell chickens produced by the method has the advantages of ideal shape, complete disease purification and excellent production performance. A new green-shell chicken variety with consistent appearance and stable performance can be accurately selected to achieve dual purposes of eggs and chickens of the green-shell chickens and meet the market demand inthe southwest.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a seed production method of three-line mating black-feathered, black-skinned and green-shell laying hens. Background technique [0002] my country's local characteristic laying hens use the blood of local breeds. After systematic selection and cultivation, the appearance characteristics of the commodity generation are improved and the production performance is improved. The eliminated hens can also be used for meat because of their delicious meat quality, satisfying Chinese consumers to eat old hen soup Traditional habits, so that the overall economic value is improved. With the improvement of people's lives, their egg consumption has diversified demands. As an emerging egg product, green-shell eggs have a unique appearance, low cholesterol and fat content, and are rich in various trace elements and amino acids. They can meet the needs of the high-end market ...
