As cold weather approaches, this is a good time to consider ventilation needs in livestock and poultry housing. The objective in ventilation of an animal shelter is to maintain a healthy environment for animals and workers in the facility. Excessive dusts, odors, and harmful gases may threaten health and safety of animals and humans.
Temperature extremes reduce animal and worker productivity.
Latent heat is removed through ventilation. Additionally, ventilation should provide sufficient air exchange to provide clean air for animals and remove potentially harmful gases. These gases, as well as other harmful gases and dusts, should be removed in order to maintain a healthy environment for animals and workers. Sensible heat balance is likely to be the determining factor in ventilation design. However, ventilation is still very important.
