First, the appropriate temperature for temperature-control eggs hatching is 22 °C ~ 37 °C, the optimum temperature is 28 °C ~ 35 °C. 38 °C is a critical high temperature, more than 38 °C will cause the death of all embryos, the critical temperature is 22 °C, below 22 °C embryonic development has stopped. The best temperature control during incubation is between 30°C and 35°C. In addition, the number of days needed for hatching is related to the temperature. The accumulated temperature of incubation (incubation temperature incubation time) is generally 36,000 degrees. Within the suitable temperature range, the higher the temperature, the shorter the incubation time. In the incubation process, the temperature should be stable, and the temperature difference should not exceed 3°C. The change is too great and it will affect hatching. It is best to use a hothouse for hatching, and you can also install a high-power bulb in the room to adjust the room temperature and maintain the optimum temperature for hatching.
Second, control of humidity, embryonic development must have a certain amount of water as a hatching bed to normal development. The moisture content of sand is preferably 7% to 8%, and the relative humidity is 81% to 82%. When the sand bed surface is dry. Sprinkle water, but do not spray too much water.é³– Incubation is resistant to low humidity and weak to high humidity. The optimal humidity standard is that the hand grips sand without water and can form a mass, but the touch is loose.
Third, to control the thickness of sand coated eggs, the thickness of eggs covered with sand also directly affect the hatching rate of eggs. When you put the quail eggs, you should lay 2~3cm thick sand on the bottom of the incubator. The distance between the eggs and the eggs is about 1cm. You can put 2~3 layers and lay 1~2cm between each layer. Thick sand, the top layer of sand 3 to 4 cm thick, this treatment is easy to control the temperature and humidity, is conducive to the hatching eggs.
Fourth, to prevent human interference and predators in the hatching eggs, should maintain a quiet environment. The first 30 days of the egg hatching process are sensitive to vibration and are prone to necrosis. So don't flip the eggs during this time. In addition, it is necessary to prevent snakes and rats from invading during hatching and steal eggs. The odor of the oyster shell is extremely strong, and it is dangerous for the ant to bite it and drag it away. So prevent ants from entering the hatchery.
Key points for improving the hatchability of quail eggs
In recent years, the artificial breeding of alfalfa has developed rapidly, and how to increase the artificial hatching rate of alfalfa eggs is a problem faced by a large number of specialized breeding families. Improve the hatching rate of quail eggs. During the incubation process, be sure to grasp the following points:
