Embodiment 1

[0025] A method for improving the fertilization rate of native chicken breeding eggs, comprising the following steps:

[0026] (1) Selection of breeder chickens: choose well-proportioned, healthy and strong, mature young chickens, the ratio of roosters to hens is 1:14, increase the number of hens in the distribution of semen, increase the fertilization rate of breeding eggs, and obtain breeders;

[0027] (2) Mixed breeding of breeders: 10-12 days before the breeding period, the roosters and hens are mixed and raised, and the breeding density is 2-3 birds / m 2 , the temperature is 24°C, the humidity is 74%, the light is 1350lx, the light is 5 hours, and the darkness is 3 hours, and the mixed breeder chickens are obtained;

[0028] (3) Separation of breeding chickens: 4~5 days before the breeding period, eliminate unqualified breeding chickens, keep the ratio of cocks and hens at 1:14, and separate the cocks and hens of mixed breeding chickens, Breeding density is 4~5 / m 2 , the...

Embodiment 2

[0042] A method for improving the fertilization rate of native chicken breeding eggs, comprising the following steps:

[0043] (1) Breeder chicken selection: choose well-proportioned, healthy, strong, and mature young chickens, and the ratio of roosters to hens is 1:15, so as to increase the distribution of semen and the number of hens, increase the fertilization rate of breeding eggs, and obtain breeding chickens;

[0044] (2) Mixed breeding of breeders: 10-12 days before the breeding period, the roosters and hens are mixed and raised, and the breeding density is 2-3 birds / m 2 , the temperature is 24.5°C, the humidity is 74%, the light is 1300lx, the light is 5 hours, and the darkness is 3 hours, and the mixed breeder chickens are obtained;

[0045] (3) Separate breeder chickens: 4-5 days before the breeding period, eliminate unqualified breeder chickens, keep the ratio of roosters and hens at 1:15, and separate the roosters and hens of mixed breeder chickens. Breeding densi...

Embodiment 3

[0059] A method for improving the fertilization rate of native chicken breeding eggs, comprising the following steps:

[0060] (1) Selection of breeder chickens: choose well-proportioned, healthy, strong, and mature young chickens, the ratio of roosters to hens is 1:16, increase the number of hens in the distribution of semen, increase the fertilization rate of breeding eggs, and obtain breeder chickens;

[0061] (2) Mixed breeding of breeders: 10-12 days before the breeding period, the roosters and hens are mixed and raised, and the breeding density is 2-3 birds / m 2 , the temperature is 25°C, the humidity is 75%, the light is 1400lx, the light is 5 hours, and the darkness is 3 hours, and the mixed breeder chickens are obtained;

[0062] (3) Separation of breeding chickens: 4~5 days before the breeding period, eliminate unqualified breeding chickens, keep the ratio of cocks and hens at 1:16, and separate the cocks and hens of mixed breeding chickens, Breeding density is 4~5 / m...

Abstract

The invention mainly relates to the field of breeding technology and discloses a native chicken hatching egg fertility rate increasing method. The native chicken hatching egg fertility rate increasing method comprises breeder chicken selection, breeder chicken polyculture, breeder chicken separated culturing, breeder cock semen collection, breeder hen semen deposition, breeder chicken rearing and protection and hen feeding. The native chicken hatching egg fertility rate increasing method is simple and improves the percentage of fertilized eggs of native chicken hatching eggs to 97.6% and the economic income by 10.3%; 10-12 days before the application period, cocks and hens are cultured in a mixed mode at appropriate temperature with intermittent lighting to enhance the environmental adaptability of breeder chicken, to accelerate heat of the native chicken, to facilitate collective semen collection and deposition and accordingly to save the breeding cost; 4-5 days before the application period, the cocks and the hens are cultured in a separated mode and fed with different feedstuff to adjust the pH of the environment that chicken germ cells live, the temperature is reduced, weak intermittent lighting is applied, the lighting time is prolonged, metabolism of the breeder chicken is accelerated, the environmental adaptability and the stress resistance can be enhanced, maturation of the germ cells of the cocks and the hens can be promoted, viability of the germ cells can be improved and increase of percentage of the fertilized eggs can be achieved.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a method for improving the fertilization rate of chicken breeding eggs. Background technique [0002] Local chickens are also called grass chickens and stupid chickens. They refer to broilers raised in mountains, forests and orchards. They have the characteristics of being resistant to rough feeding, strong nesting ability and strong disease resistance. Chicken eggs are rich in nutrition, taste delicious and tender. Chicken meat is tender, delicious and nutritious, rich in protein, amino acids, vitamins, phosphorus, iron, copper and zinc, which can strengthen the body, improve immunity and promote intelligence Growth, tonifying kidney and essence, and relieving fatigue. With the enhancement of people's awareness of health care, native chickens are becoming more and more popular, and the scale of breeding is also expanding. [0003] In the current breeding method of nati...
