Problems solved by technology

In particular, hemp-feathered chickens that produce green-shell eggs among local chicken breeds are popular among consumers in many regions. Economic benefits of green-shell laying hens
In addition, the traditional anal turning method to identify male and female hens is not only slow, heavy workload, and low accuracy, but also has certain damage to the chicks, affecting the survival and growth of the chicks

Abstract

The invention discloses a breeding method for speckle-feather laying hens laying green-shell eggs. The breeding method comprises the following steps: firstly, hybridizing cocks of a low-feathering Rhode Island Red strain with Sussex hens to obtain F1-generation chicks, wherein hatched female chicks are red-feather female chicks, hatched male chicks are white-feather female chicks, and the red-feather female chicks are bred into adult hens; 2, mating fast-feathering speckle-feather cocks hatched by green-shell eggs with the F1-generation red-feather hens obtained in the step 1 to obtain F2-geneeration chicks, wherein the hatched male chicks are slow-feathering chicks, the hatched female chicks are fast-feathering chicks, and the adult female chicks are speckle-feather hens laying green-shell eggs. According to the production method, the egg laying quantity is greatly increased while the two characteristics, namely speckle feathers and laying of green-shell eggs are kept; finally, the female chicks and the male chicks are identified by means of the feathering speed, and thus the economic benefit of breeding the speckle-feather laying hens laying the green-shell eggs is increased.

Description

technical field [0001] The invention belongs to the technical field of poultry breed breeding, and in particular relates to a method for producing flax-feathered green-shell hens through the genetic rule of two pairs of sex-associated traits, feather color and feather speed. Background technique [0002] my country's local chicken breeds are rich in resources, with outstanding advantages and distinctive characteristics. For example, green-shell layer hens produce green-shell eggs with high nutritional value, which are rich in lecithin, amino acids, vitamins, and trace elements (iodine, zinc, selenium, etc.) Etc.), is a kind of nutritious good product, the market price is higher. In particular, hemp-feathered chickens that produce green-shell eggs among local chicken breeds are popular among consumers in many regions. Economic benefits of green-shell layer hen farming. In addition, the traditional anal turning method to identify male and female hens is not only slow, heavy w...
