Embodiment 1

[0024] A method for cultivating a yellow-feather high-yield laying hen strain comprises the following steps:

[0025] 100 adult roosters of Royal Concubine Chicken, 2,000 adult hens of Luodao White Chicken, artificial insemination and mating with mixed semen, 10,000 breeding eggs were collected for several days, hatched, and 8,500 chicks were obtained, gender identification by anal turning method, and 300 male chicks were retained Only, the mother and chicks are all kept;

[0026] Conventional feeding until 28 weeks old, select 150 healthy roosters, 3000 hens, artificial insemination and mating, collect breeding eggs for several days, obtain 20000 breeding eggs, hatch, and obtain 16000 chicks; the appearance characteristics of chicks will be separated, preliminary selection For chicks, dark brown, brown, and white chicks with plumage color were eliminated, and anal sex identification was carried out, leaving 500 male chicks and 2,000 female chicks that met the requirements.

Abstract

The invention provides a cultivation method of yellow feathered high-laying chicken strain. The method comprises the following steps that (1) a hybridized combination is selected by taking a royal chicken a male parameter and a Rhode Island white chicken as a female parent, copulation is carried out by large-group artificial insemination, hatching eggs are collected, and chicks are obtained by hatching; (2) after that the chicks obtained in the step (1) are bred normally to sexual maturity, large-group intercrossing hybridization is carried out on hens and cocks, hatching eggs are collected, and chicks are obtained by hatching; (3) after that the chicks obtained in the step (2) are normally bred to 10 weeks, breeding hens are selected according to appearances, and chicks are obtained by hatching; and (4) after that the chicks obtained in the step (3) are normally bred to 10 weeks, breeding hens are selected according to appearances and are marked as a generation F0. The new laying hensystem with stable laying performance is cultivated, the high laying amount is ensured, the high equality of eggs is also ensured, and the chickens are yellow-feathered and small in size.

Description

technical field [0001] The invention relates to the field of breeding new breeds of chickens, in particular to a method for cultivating a yellow-feathered high-yielding laying hen strain. Background technique [0002] my country's annual egg output is more than 20 million tons, ranking first in the world, and its per capita egg consumption ranks among the top in the world. There are two main types of laying hens in my country. One is the high-yield laying hens introduced from abroad or independently cultivated in my country. The annual egg production is high, the egg weight is more than 60 grams, and the eggshell is brown or light brown, commonly known as "foreign eggs". The other is our country's special layer hens, which are bred by using the genetic resources of local chickens. The egg weight is about 50 grams, and the eggshell is pink, commonly known as "native eggs". According to estimates, the annual output of special eggs in my country is about 3 million tons, with a...
