Fresh and healthy air is essential for both humans as well as animals to breathe. Ventilation in animal housing provides fresh air by replacing moisture and odors.
It also provides air movement that promotes cooling and improves air quality for the animals. Farm fans (also known as “แฟนฟาร์ม” in the Thai language) are widely used for ventilation purposes.
There are two types of ventilation systems used in animal housing:-

- Passive Ventilation: This ventilation is also known as natural ventilation. It is driven by natural airflow around the building. This ventilation can be used alone with the help of windows and doors or can be combined with some types of mechanical ventilation.
In many cases, natural ventilation is not sufficient since the air exchange rates and inside temperature fluctuate with outside changes and wind conditions.
- Mechanical Ventilation: This ventilation needs equipment like fans, air inlets, and thermostats. This ventilation is needed where natural ventilation is not sufficient.
This ventilation is common in calf housing, milk houses, lambing sheds, nursery buildings, swine farrowing, and calf housing. The most common approach is to use fans to blow air and purify the unwanted smells of the building.
So, ventilation is provided by two ways in animal housing. If the wind is blowing outside of the building then ventilation is done by the doors and windows and if the wind is not blowing then mechanical ventilation is used to control the temperature of the building.
