Ventilation During the development of embryos, it is necessary to continuously inhale oxygen and expel carbon dioxide.
hatch The oxygen demand of 1-4 day old embryos is low and gradually increases after 4 days.
Ventilation should pay attention to the following points. hatch The height of the chemical chamber directly affects the ventilation.
The height of the modern chicken farm hatchery should be above 3.5 meters. Or the top of the incubator should be at least 1 meter away from the roof.
The air should be fresh, and the indoor air cannot be recycled. It is best to set up fresh air passages or inlets and exhaust gas discharge passages in the incubator.
Altitude has an effect on hatchability. Ventilation, temperature and humidity affect each other, and attention should be paid to the coordination between the three.
Gradually increase ventilation with embryo age, 1-4 days, 5-11 days and 12-21 days of embryo age Open 1/3, 2/3 and full opening of the intake and exhaust vents in sequence.
There are many more conditions, see the next article.
