Cultivation method of yellow feathered high-laying chicken strain

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...

Problems solved by technology

However, the egg production performance of local yellow-feather chicken breeds in my country is not high, and the egg production at 72 weeks is only 150-200, which is far lower than the level of 300 at 72 weeks for high-yield layer chickens. Therefore, the market’s demand for high egg production Yellow feather chickens are in urgent need
