Hatching eggs with hatching machine

Because of the thick shells of the mountain eggs, the small area of ​​the swept eggs and the strict sealing of the pores directly affect the gas exchange, moisture evaporation, heat conduction, and hatching of the clam shells. Because the hatching rate is low, it becomes a major problem in production. Incubation of hatching poultry since the pheasant hatching, the hatching rate is 10-20% higher than conventional hatchery technology. The new technology for incubating eggs in this equipment is introduced as follows:

First, the composition of horizontal incubator water thermostat

The horizontal incubating bird water tank is made of zinc-iron sheet metal. The outer iron basket is 7cm longer than the inner iron basket, 7cm wide, and 9cm high. The two-layer tin baskets are welded to form a sandwich box. The corners are equipped with thermostats. Surrounding with saw foam insulation, saw foam peripheral brick, cabinet inside the rice, bamboo mats, gauze, mountain eggs with 0.15% solution of Xinjie soaked for 3 minutes after disinfection, can be loaded eggs hatch, through the cabinet sandwich Injecting hot water can accurately control the temperature within the required range, and at the same time, by opening high, reducing, thickening, thinning or lifting the cover of the incubator box, the problems of oxygen supply, cool eggs, and humidification of the embryonic eggs can be solved. It is in a state of good natural hatching, significantly increasing the shelling rate of mountain eggs and the adaptability of the chicks to the natural environment.

Second, the humidity

Pre-incubation eggs preheated 6-8 hours, egg temperature 36-38 °C; 1-7 days 38.8-39.2 °C; 8-14 days 38.5-38-8 °C; 15-20 days 38-38.5 °C; 24 days 38.5-39.2°C. In this way, the embryos are normal, and the allantoic capsules are closed after 14 to 15 days, enclosing all the proteins, ensuring that the embryos fully utilize the proteins after 21 days to increase the hatching rate of the mountain eggs.

Third, the humidity

The humidity of the mountain egg is preferably two high and middle level. The humidity in the early stage is 60-65%, the middle stage is 55-60%, the later period is 60-68%, and the hatching period is 70-75%.

Fourth, turn the egg

Incubate mountain eggs with the horizontal hatching water incubator, turn eggs once every 8 hours for 1-20 days, turn the egg at an angle of 180 degrees; after 21 days, do not turn the eggs in the hatching period, and only adjust the heart to meet the embryo Demand for development, hatching results are ideal.

Fifth, cool eggs

In the early stage, generally do not cool eggs, in accordance with the above Schwing program, the egg temperature in the middle and later period up to 38.8 °C, the egg surface area is relatively small, small pores, heat slowly, this time can cool the eggs can enhance the embryo's gas exchange, remove the egg product Heat, hatched to 14-16 days old, open the lid, cool eggs once a day: 20 days later, the physiological heat, cool eggs 2-4 times a day, cool egg length ranging, flexible according to the situation, when the temperature of the egg Continue to hatch at 35 degrees.

Sixth, hatching

Spraying water is one of the keys to improving the hatching rate of mountain eggs. After 21 days, the embryo sprays warm water of 36-38°C (advanced water spray is unfavorable for closing the allantoic capsule), sprays once a day, and sprays the eggs until it is soaked. After drying, continue to hatch. Under repeated cooling eggs and water spray, the calcium carbonate of the eggshell becomes calcium bicarbonate, and its nature changes from hard to crunchy. The chicks are easy to be broken and the stillbirth during hatching is reduced.
