Embodiment 1

[0021] The high-efficiency and high-quality static chicken breeding and free-range breeding method of the present embodiment specifically comprise the following steps:

[0022] 1. Purebred breeding: select chickens from Jingning County chicken farmers until 5-6 months old, with good development, fast growth, good meat quality, healthy body, medium physique, high head and neck, towering tail feathers, well-developed chest, broad back and The rooster with a long, strong shin and toe, similar to a rectangular body with both eggs and meat, and a hen with a small head and a wide back and a round belly are used as the male and female parents, respectively, and the male and female parents are kept in isolation. The first generation to the fifth generation Generations were mated according to the male-female ratio of 1:12, 1:11, 1:10, 1:9, and 1:8, and artificial breeding was used to produce breeding eggs. The breeding roosters collected semen every 4 days and rested for 2 days. The he...

Embodiment 2

[0029] Embodiment 2: choose 240 breeding hens that are healthy and disease-free, the same age, and body weight are even, are randomly divided into 2 groups, are divided into a control group and a test group, and each group establishes 3 repetitions (each repeats 40), The control group and the test group were rationed with breeding cocks according to the male-to-female ratio of 1:6. The breeding cocks in the control group were not given special feed fortification before semen collection, and the test group was given special feed one day before the breeding cocks described in Example 1. Intensified, artificial insemination techniques were used in both the control group and the test group; the test period was 60 days, and the number of eggs laid in each group was collected and recorded one week after the start of the test.

[0030] The measurement results are shown in Table 1

[0031] The impact of table 1 special feed fortification on the fertilization rate of breeding eggs (per...

Embodiment 3

[0034] Embodiment 3: Randomly select 1200 fertilized eggs of the test group in Example 2, divide into 2 groups, test group and control group, each group establishes 3 repetitions (each repeats 200 fertilized eggs).

[0035] The treatment method of the control group: spray the surface of the eggs with 0.1% bromogeramine solution for disinfection, and then put them into the hatching room for hatching.

[0036] Treatment method of the test group: according to the egg disinfection and hatching method described in Example 1, the treatment was carried out.

[0037] The measurement results are shown in Table 2:

[0038] Table 2 The influence of hatching and brooding methods on fertilized eggs

[0039]

[0040] As can be seen from Table 2, compared with the control group, the hatching rate of inseminated eggs through the brooding method of the present invention is as high as 95%, which is 13.6% higher than that of the control group, the hatching days are advanced by 3 days, and th...

Abstract

The invention discloses an efficient method for breeding and freely raising high-quality Jing Yuan chickens and belongs to the cultivation technical field. The efficient method for breeding and freely raising high-quality Jing Yuan chickens comprises following steps: purebred seed selecting, purebred propagating, hatching egg disinfecting, hatching, brooding, free raising management and disease preventing and controlling. The breeding time is shortened, the breeding precision, the egg fertilization rate, the hatching rate and the survival rate of broods are increased and the hatching period of chicks is shortened by using the method of artificial breed protection and selection and artificial insemination of the Jing Yuan chicken of the present invention; at the same time, the method of the present invention adopts Chinese herbal medicine to control chicken diseases, improve the resistance of chickens, reduce the incidence of pullorum disease, mycosis and coccidiosis; by means of the method of ecological freely raising Jing Yuan chicken, the output of eggs is increased, the oviposition time is advanced, the slaughtering time is shortened, the body weights of hens and cocks when slaughtering are substantially increased so that the chicken is delicious, there is no residual medicine and the chicken quality of Jing Yuan chicken is increased.

Description

technical field [0001] The invention belongs to the technical field of breeding, and relates to a method for breeding native chickens, in particular to a method for breeding and free-range chickens with high efficiency and high quality. Background technique [0002] Jingyuan chicken, also known as Jingning chicken and Guyuan chicken, is an excellent egg and meat chicken breed that can withstand high cold and arid climate in the Loess Plateau. The main production areas are in Jingning County of Gansu Province and Guyuan County of Ningxia Hui Autonomous Region. This area is located in the west of Liupan Mountain and the southwest of Guan Mountain. It belongs to the hilly and gully landform of the Loess Plateau. , so the local chicken breeding is mainly free-range, because of the unique climatic conditions, geographical environment and soil cultivation methods, coupled with the fact that few foreign species have been introduced for breeding. After years of breeding and breeding...
