title: Calculation of ventilation needs for confined cattle.
abstract: Fundamental to maintaining a healthy environment in a mechanically ventilated livestock building is a continuous flow of air, with at least 4 exchanges per hour to remove moisture and aerosol contaminants. A correctly designed fresh air intake system is mandatory for uniform air distribution. Proper insulation is essential. Supplemental heat may be required to permit continuous ventilation while maintaining an ambient temperature suitable for preserving animal health.
