Dear friends! We decided to touch on an important question that interests many poultry farmers: what should be the humidity in the incubator and what is it needed for?
There are a number of factors that affect the output of birds, one of them is the microclimate in the incubator. Humidity is a certain parameter, lowering or increasing, which can achieve the best results.
Humidity is determined by the amount of water vapor. You can measure the humidity in the incubator using special devices-a hygrometer or a psychrometer.
What humidity in the incubator is necessary for fruit maturation depends on the period of egg maturation. So:
in the first week, the organs of the future chick are formed, the humidity should be 50-60%;
from 8 to 11 days humidity is increased to 60-65%, during this period the respiratory and circulatory system and its skeleton are formed. This level of humidity contributes to the optimal formation of the embryo;
from 12 to 17 days reduce to 50%. During this period, the claws and beak become hard, fluff appears and the first outlines of the chick are formed under the shell. Then they reduce it to 45% for two days. After that, the humidity is increased to 66% and the last days of incubation are maintained at this level
After the Chicks are released from the shell, they are left in the chamber until they are completely dry. At the same time, it is necessary to turn on the fan in the chamber at full power and open the lid 3 times a day to completely ventilate the incubator.
As we have already said, humidity in the incubator affects the percentage of offspring output. When do I need to adjust indicators?
1. When the ovoscoping revealed a large amount of adhesive amniotic fluid
2. In the chamber there is mold
3. Later, and simultaneously starts the PIP dense shell eggs
4. When biting, a substance appears that prevents the appearance of the chick.
These signs indicate errors during incubation that need to be identified and corrected!
ERRORS DURING INCUBATION?!
Often farmers allow an overabundance of water putting, baths in the incubator, hoping that the humidity will only have a positive effect on the output. But this is a misconception that leads to problems in the development of embryos.
The dryness of air. In the last days of incubation, the air should not be dry, as this can create solidification of the shells inside the egg and the shell itself. Future Chicks will have to make more effort to hatch, and those that are not so strong will not be able to get out of the egg at all. Conversely, excessive humidity can cause mold and bacteria to appear on the inner surfaces of the incubator, as well as on the eggshells.
CONCLUSION
Do you want to achieve a high percentage of output and get high-quality young? It is necessary to monitor and maintain the humidity level in the incubator chamber. Stimul Inc incubators are easy to use and maintain the humidity level according to the parameters that are defined on the control unit.a clear and convenient microclimate control system will help to achieve a high % when hatching Chicks.
