Embodiment

[0034] A method for cultivating reed feather green-shell laying hens, comprising the following steps:

[0035] (1) Determining the breeding goal: the bred new line has the appearance characteristics of reed flower feathers, the number of eggs laid at 72 weeks old is more than 200, the eggshell color is green, the average egg weight is 45-50g, and the egg quality is good.

[0036] (2) Selection of breeding materials: The rooster comes from Wenshang Luhua chicken. This breed has the appearance characteristics of reed flower feathers. At 72 weeks old, the egg production is 180, the average egg weight is 45g, the eggshell color is pink, and the egg quality is good. The hens come from Xinyang green-shell layer hens (supporting line) commercial generation hens. The egg production of this breed is 230 at the age of 72 weeks, the average egg weight is 50g, and the eggshell color is light green. By crossing the above two chicken breeds, the reed flower feather and green shell genes are...

Abstract

The invention relates to the technical field of layer breeding, and specifically provides a breeding method for layers with the characteristics of reed feathers and green shell eggs. According to the method, through a breeding technology combining optimization selection of parent strains, a modern conventional breeding technology and a molecular detection technology, the new high-quality layers with the characteristics of the reed feathers and the green shell eggs are quickly bred, the new strain has obvious characteristics and excellent performance, and the breeding benefits are high; the obtained strain has the appearance characteristics of a single comb, reed feathers, green shell eggs, flesh-colored shanks and beautiful body shapes; the obtained strain has the performance characteristics that the age at first egg is 155 days old, the average weight at first egg of the hens is 1.35 kg, the number of eggs laid by each 72-week-old hen in a hen cage is 210, the average weight of eggs of the 43-week-old hens is 28 g, and the quality of the eggs is excellent; on the premise of keeping excellent egg quality, the annual egg yield of the new strain is increased by 20% or above compared with ordinary local chickens.

Description

technical field [0001] The invention relates to the field of biotechnology, and specifically provides a method for cultivating reed feather green-shell laying hens. Background technique [0002] Outer packaging traits and egg quality are the direction of high-quality laying hen breeding. Cultivating new strains of high-quality laying hens with beautiful body shape and good egg quality can meet the market's demand for high-end egg products. In recent years, eggs with the green shell logo have been favored by consumers because of their beautiful appearance and comprehensive nutrition, and their market share has increased year by year. Wenshang reed chicken with barred feathers is an excellent local chicken breed in my country. It has a beautiful body and good egg quality, and enjoys a high reputation in China. [0003] Reed flower gene B is a dominant genetic gene located on the Z sex chromosome. At present, there is no effective genetic detection method, but the principle o...
