Embodiment 1

[0024] A method for cultivating a high-yielding laying hen strain with black and white flower feathers 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, leaving There are 500 male chicks and 2,000 female chicks that meet the requirements.

[0027] After conventional feeding until 15 weeks old, the seeds are selected according to the appearance character...

Abstract

The invention provides a cultivation method of black and white feathered high-laying chicken strain. The method comprises the following steps that (1) a hybridized combination is selected by taking aroyal chicken a male parameter and a Rhode Island white chicken as a female parent on the basis of hybridized combination test and data analysis and screening, copulation is carried out by large-groupartificial 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, a new laying hen system with stable laying performance is cultivated. The high laying amount is ensured, the high equality of eggs is also ensured, and the hens whose appearance is featured as native laying hens are wed out.

Description

technical field [0001] The invention relates to the field of breeding new breeds of chickens, in particular to a method for cultivating a black-and-white flower feather 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 mainly two types of laying hens in my country. One is the high-yield laying hens introduced from abroad or independently cultivated in my country. The egg weight is more than 60 grams, and the eggshell is brown or light brown, commonly known as "foreign eggs". The other is the layer hen with Chinese characteristics, which is bred by using the genetic resources of local chickens in our country. The egg weighs 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 ...
