Hybrid matching method for red-feathered chickens to produce pink-pink shell eggs

Abstract

The invention relates to a hybridization matching method for red-feathered chickens to produce pink-pink shell eggs, comprising the following steps: Step S1: taking Luodao red roosters and Luodao red hens as the male parent line and the male parental line, and cultivating the male parent Luodao red Rooster; Step S2: Use Luodao White Rooster and Bailai Aircraft Carrier Chicken as the female parent and female parent, and cultivate the female parent; Step S3: Use the male parent Luodao Red Rooster and the female parent hen with colored spots to cultivate commercial egg substitutes Chicken, a new breed of red-pink eggs, realizes male and female differentiation through feather color. Among them, red feathers are hens, and non-red feathers are roosters. The egg shell color of the commercial substitute hen of the present invention is red pink, and the feather color is red feather, which can fill the blank of this kind of laying hen breed in my country, and because the egg shell color is between brown shell eggs and pink shell eggs, it further enriches the The eggshell color type of domestic eggs meets the market demand and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of matching breeding of new breeds of laying hens, in particular to a hybrid matching method for red-feathered chickens to produce pink-pink shell eggs. Background technique [0002] Affected by traditional consumption habits, the egg consumption of urban and rural residents in China is mainly fresh eggs, and the eggshell color of eggs is a key concern of consumers. In recent years, the proportion of powder-shell eggs in the market has continued to rise, approaching 40%. At present, high-yielding commercial layers that produce powder-shell eggs are mainly produced by orthogonal or inverse mating of brown-shell and white-shell hens. The eggshell color is between brown and white (the average value of L value in the whole process around 80). With the increase in the market demand for branded eggs, consumers' preference for eggs with red-pink shells has been increasing year by year. The eggshells are darker th...

[0003] At the same time, red-feathered layer hens (commonly known as old hens) have the advantages of easy sale and high price, and the consumer market also favors them. Therefore, this breed of layer hens is favored by breeders. However, there is a lack of such red-feather chickens in the market The variety that produces pink-pink eggs, and the eggshell color heritability of laying hens is medium, the breeding progress is slow, and the effect is not good; therefore, there is an urgent need for a method to guide the cultivation of new varieties of red-feathered chickens that produce red-pink eggs
