Embodiment Construction

[0014] The hatching site is Shanmuhe Avenue, Chengguan Town, Shibing County, among the green mountains and green waters of Miaoling Mountains, which is a low hilly area with a pleasant climate.

[0015] (1) Put 1 rooster and 12 hens in a chicken coop for natural mating, choose eggs with glossy appearance, small air chamber, clean eggshell, suitable egg weight, oval shape;

[0016] (2) The storage period of breeding eggs shall not exceed 1 week, the storage temperature shall be 15-18°C, the relative humidity shall be maintained at 75%-80%, and the storage of breeding eggs shall be ventilated;

[0017] (3) After each collection of eggs, put them in the nearby disinfection room or send them to the incubator for disinfection immediately. After detoxification, put them in the egg bank for storage. After the water droplets on the surface of the breeding eggs disappear, fumigate the tip poison for 20 minutes. After the surface temperature of the eggs reaches room temperature, the egg...

Abstract

The invention discloses an improved variety breeding method of green-eggshell chicken, wherein the method comprises mating, selecting eggs, naturally pre-heating in a hatching house and arranging a hatching machine sensor; after hatching from the first day to the twentieth day, the eggs should be turned over at every two hours and the turned angle is 90 degree so as to make each part of the embryo be heated uniformly and avoid the embryo stick to the shell; after hatching, at the seventh say, shell less eggs and addle eggs are elected out through lighting; after hatching to the eighteenth day, living breed eggs should be placed on a disc; at the twentieth day, the breed eggs begin to give berth to young chicken and finish at the twenty-first day; and after the young chicken coming out of the eggshells, the young chickens should be selected out every two hours. According to the invention, each process from selecting eggs to hatching is effectively controlled; part of bad quality eggs can be prevented from hatching by the selection of eggs at the first step, so the continuation of good quality green-eggshell chicken is ensured; at the same time, the hatching process is effectively controlled and the humidity requirement of the breed eggs during the hatching process is satisfied, thus the hatching rate of the green-shell eggs are improved and the hatched young chicken are healthy.

Description

technical field [0001] The invention relates to a method for breeding fine breeds of green-shell laying hens. Background technique [0002] There are many varieties of local chickens in my country, and some varieties of local chickens in China have the characteristics of producing green-shell eggs, which are called green-shell eggs. Green-shell chicken has the characteristics of strong disease resistance, roughage resistance and good feeding. Its meat is tender, delicious, and the soup is mellow. Green, egg yolk is big, orange-yellow, egg white is thick, protein is thick, delicate, easy to be digested and absorbed by the human body, contains a lot of lecithin, vitamins A, B, E and trace elements iodine, zinc, selenium, the content of amino acids is higher than ordinary The egg yolk is 7-10 times higher, the yolk is 8% larger than the grass egg yolk, and the yolk pigment can reach Roche grade 13. The yolk pigment of ordinary eggs is generally Roche grade 4-5, which is high i...
