In the incubation management of growth, although the storage time of eggs after production is relatively short, it is also impossible to hatch immediately after production. Therefore, seed eggs should be stored for a certain time before being hatched. Even if the breeding eggs come from excellent duck flocks; After strict selection, the seed eggs with good quality, Xuguobao Amur Tiger service parts are poor, and the storage method is improper, which has a negative impact on the incubation effect. Especially in winter and summer. Therefore, it is necessary to create a suitable storage condition and methods for seed eggs.

（1） Requirements for egg storage room

Large hatcheries should have special egg storage rooms. The storage room shall be well insulated. A windowless closed room.

In addition, the storage room shall also be equipped with thermostatically controlled heating equipment and refrigeration equipment, as well as automatic humidity controller. The distance between the egg storage room and the barn should be as far as possible, and it should be convenient for cleaning and disinfection.

（2） Suitable temperature and humidity

The ideal temperature for storage of seed eggs is 13-16 ℃, but the storage time is not different. It is better to keep the eggs within 7 days and control them at 15 ℃; 11 ℃ is appropriate for more than 7 days. High temperature has a great impact on the hatchability of breeding eggs. When the storage temperature is higher than 23 ℃, the embryo begins to develop slowly. Although the development degree is limited, the cell metabolism will gradually lead to the aging and death of the embryo; On the contrary, if the temperature is too low, it will also cause the death of the embryo and affect the hatching rate. When the temperature is lower than 0 ℃, the seed egg will lose its hatching ability due to freezing. It should be noted that under any circumstances, the seed eggs should be stored in a relatively stable temperature environment.

Therefore, before storage, if the temperature of the seed egg is higher than the dry storage temperature, it should be gradually cooled to make the egg temperature close to the temperature of the storage room, and then put it into the storage room. If the temperature is too high, the egg surface will regain moisture, and the seed egg will easily become moldy and deteriorated; If the humidity is too low, the water in the egg is evaporating, which will inevitably affect the hatching effect. The moisture content of the preserved egg is the best. Generally, the relative humidity in the storage room is within the range of 75-80%.
