Problems solved by technology

[0003] With the gradual increase in the demand for eggs, the demand for laying hens is also increasing. However, the storage time of laying hen eggs is at most 12 days, and the hatching rate of laying hens will be significantly reduced in 10-12 days, and can only reach 60~ 65%, if the eggs cannot be hatched in time, it will cause great economic losses. Therefore, an effective method for storing eggs of laying hens is needed to prolong the storage time of breeding eggs of laying hens

Embodiment 1

[0019] A method for preserving eggs of laying hens, comprising the following steps:

[0020] (1) Breeding egg selection: select fresh laying hen eggs with uniform color, uniform size, and smooth surface, with an egg shape index of 0.76~0.78, to obtain breeding eggs;

[0021] (2) Egg washing: place the egg with the big end down, let the eluent flow to the big end slowly, place it on the hollow egg board, spray the eluent on the egg board, and the amount of each spray is 10ml according to the weight of the egg / kg, spray once every 5 hours, spray 3 times in a row, turn the eggs over, with the big head up, and let it stand for 3 days to make the big head dry quickly, avoid the eluent from directly impacting the big head, and avoid a large amount of liquid from quickly penetrating into the eggshell. Maintain the shrinkage and integrity of the air sac, prolong the storage time of the eggs, and rinse the eggs;

[0022] (3) Egg spray film: evenly spray the egg protection solution on...

Embodiment 2

[0031] A method for preserving eggs of laying hens, comprising the following steps:

[0032] (1) Breeding egg selection: select fresh laying hen eggs with uniform color, uniform size, and smooth surface, with an egg shape index of 0.76~0.78, to obtain breeding eggs;

[0033] (2) Egg washing: place the eggs with the big end down, let the eluent slowly flow to the big end, place it on the hollow egg board, spray the eluent on the egg board, and the amount of each spray is 11ml based on the weight of the egg / kg, spray once every 6 hours, spray 3 times in a row, turn the eggs over, with the big head up, and let it stand for 3~4 days to dry the big head quickly, avoid the direct impact of the eluent on the big head, and avoid a large amount of liquid quickly penetrating into the egg shell, maintain the shrinkage and integrity of the air sac, prolong the storage time of the eggs, and wash the eggs;

Embodiment 3

[0043] A method for preserving eggs of laying hens, comprising the following steps:

[0044] (1) Breeding egg selection: select fresh laying hen eggs with uniform color, uniform size, and smooth surface, with an egg shape index of 0.76~0.78, to obtain breeding eggs;

[0045] (2) Egg washing: place the egg with the big end down, let the eluent slowly flow to the big end, place it on the hollow egg board, and spray the egg washing liquid on the egg board, based on the weight of the egg, the amount of each spray is 12ml / kg, spray once every 7 hours, spray 4 times in a row, turn the eggs over, with the big head up, and let it stand for 3~4 days to dry the big head quickly, avoid the direct impact of the eluent on the big head, and avoid a large amount of liquid quickly penetrating into the egg shell, maintain the shrinkage and integrity of the air sac, prolong the storage time of the eggs, and wash the eggs;

Abstract

The invention mainly relates to the technical field of breeding, and discloses a method for preserving laying hen hatching eggs. The method comprises the steps of hatching egg selection, hatching egg elution and hatching egg film spraying. The method is simple and convenient to operate, the preservation time of the hatching eggs is prolonged to 18-20 days, the hatchability reaches 90.8%, and economic income is increased by 16.8%. The fresh hatching eggs are placed in a hollowed egg plate, elution liquid is sprayed, dirt on the surfaces of the hatching eggs is washed away, bacterium inhibition and bacterium resistance are achieved, pathogenic microorganism infection is avoided, nutritional ingredients are increased, and embryo activity is kept. The elution liquid is rich in calcium, the thickness of egg shells can be increased, the large ends are downwards during spraying, the large ends are upwards after spraying is completed, the large ends are fast dried, it is avoided that the elution liquid directly impacting on the large ends, the contractility and completeness of airbags are kept, and the preservation time of the hatching eggs is prolonged. Protection liquid is sprayed to the hatching eggs, germs on the surfaces of the hatching eggs are killed, protection films are formed on the surfaces of the hatching eggs, yolk carries out dormancy, more nutritional ingredients and high activity are reserved, and the preservation time is prolonged.

Description

technical field [0001] The invention mainly relates to the field of breeding technology, in particular to a method for preserving breeding eggs of laying hens. Background technique [0002] Laying hens refer to chickens that are raised to lay eggs to supply eggs. Unlike broiler chickens, eggs are the main source of income for raising laying hens. Eggs are rich in nutrition, contain a lot of vitamins and minerals and protein with high biological value, very suitable for human physiological needs, easy to be absorbed by the body, the utilization rate is as high as more than 98%, and the nutritional value is very high. It is one of the people's favorite foods . [0003] With the gradual increase in the demand for eggs, the demand for laying hens is also increasing. However, the storage time of laying hen eggs is at most 12 days, and the hatching rate of laying hens will be significantly reduced in 10-12 days, and can only reach 60~ 65%, if the breeding eggs cannot be hatched ...
