Technology, such as pit fans, curtains, and heaters, is being implemented into husbandry ventilation today in an effort to become more efficient at providing an optimal environment for pigs or chickens.
Husbandry Ventilation can be defined as a process for controlling several environmental factors by diluting inside air with the mixing of fresh outside air (The Service, 1990). Basically, ventilation brings in oxygen and expels or dilutes harmful dusts, gases, and undesirable odors, as well as airborne organisms and moisture from the hogs or broilers.
Negative pressure systems are the most widely used husbandry ventilation systems today. They have air inlets located at the top of the walls and the air comes out through extractors located in the ceiling. Another configuration of this system is characterized by extractors located in the lower parts of the walls or under slats, and in this way a better control of harmful gases is achieved, especially ammonia.
