Cultivation method of black and white feathered high-laying chicken strain

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 ...

Problems solved by technology

[0004] In order to solve the above-mentioned shortcomings, the present invention provides a method for cultivating a high-yielding laying hen strain with black and white flower feathers, aiming at solving the contradiction between egg yield, egg quality and quality of eliminated chickens, and cultivating a new strain of laying hens with stable production performance , can not only maintain a high egg production but also ensure the high quality of the eggs, and the appearance of the eliminated hens has the characteristics of native layer chickens
