Frequently Asked Questions
What is the ideal temperature in chicken sheds and poultry hatcheries?
The optimal climate in the first few days of chickens’ lives should stabilize in between 30°C to 32°C and be uniform throughout the environment. Above all, the shed must already be warm and at constant temperature before the chicks arrive. It is also necessary to pay the utmost attention to air speed, which in this phase must be less than 0.15m/s at ground level or at least as low as possible.
What are the advantages of gas heating in poultry farming and how can I save money?
Gas-fired hot air generators (LPG or natural gas) are very efficient and quick to heat, and in the case of direct exchange burners with air recirculation their efficiency is close to 100%. In order to significantly reduce heating costs, it is necessary that the hall is well insulated and that the climate control is managed by a control unit that monitors all important parameters, internal and external temperature and relative humidity, and carbon dioxide.
What are the advantages of hot water heating in poultry farming and how to save money?
Hot water unit heaters heat uniformly and without pollutants, it is very important to use models that guarantee optimal air circulation.
In order to significantly reduce heating costs, the building must be well insulated and the climate control must be managed by a control unit capable of monitoring all the important parameters, temperature, internal and external relative humidity and carbon dioxide.
What is the ideal relative humidity in chickens? And how important is it in the chick's first days of life?
During the first three days of life it is necessary to keep the relative humidity between 60% and 70% and in any case above 50% until the end of weaning.
This value is very important because if the relative humidity is higher or lower, you will have to adjust the internal temperature, raising the set temperature if the relative humidity is lower than 60% and lowering it if it is lower.
What to do if the climate in chicken farm is too dry?
The actual temperature felt by the animals depends on the dry bulb temperature and relative humidity, and a lower value of the latter decreases the apparent temperature. For this reason, increasing the overall temperature of the space would be a great solution to a climate that is too dry. During weaning, RH values in the 10% – 20% lower range than ideal may require an increase in room temperature of 2÷3°C.
How can I humidify my chickens house?
If there are nebulizers in the shed for summer cooling, they can be used for humidification of the chickens, otherwise some misting units with centrifugal humidifiers with integrated fan can easily achieve the goal.
What is the purpose of minimum ventilation and how to effectively control it?
Minimum ventilation is used during the weaning period and, regardless of the outside temperature, the shed must be ventilated for a minimum period of time.
It is essential to bring in sufficient fresh air from outside to remove harmful gases, excess humidity and thus ensure the correct quality of the indoor air.
For uniform air flow at the right speed it is necessary that the climate control is managed by a control unit that is able to monitor not only all the most important parameters but also the control of the internal negative pressure.
What is tunnel ventilation and how can I calculate the number of extractor fans required?
In tunnel ventilation, the fans are placed at the end head of the hall, while the air intakes are placed on the opposite side, near the front head. The direction of the air flow is consequently longitudinal.
As the speed increases, the effective temperature perceived by the broilers decreases significantly and this type of ventilation is best suited to achieving the target of 2.5÷3.0m/s.
To obtain the required air flow rate, and consequently the type and number of fans, it is sufficient to multiply the section of the hall by at least 9000 (9000m³/h/m²).
Which cooling systems can I use on my farm?
With a tunnel ventilation system, with high air velocity and high air exchange rates, it is possible to add an evaporative cooling system (adiabatic) that decreases the temperature inside the hall.
There are basically two systems, with cellulose evaporative panels, which cool the incoming air, or with low or high pressure nebulizers, generally distributed longitudinally along the hall.
It is however a good rule to condition the operation of adiabatic cooling to the external relative humidity, in the case of excessive values the system must not operate at temperatures below 27°C.
