What effect does an increase in air and ventilation in a barn have?

Increasing air and ventilation in a barn primarily decreases the levels of anaerobic bacteria. Efficient ventilation allows fresh air to circulate, which helps to remove excess moisture, odors, and harmful gases, thereby reducing the overall humidity in the environment. When air quality is improved with adequate ventilation, it creates an inhospitable environment for anaerobic bacteria, which thrive in low-oxygen conditions. As fresh air replaces stagnant air, it minimizes the buildup of waste products and promotes the growth of aerobic microorganisms that are less harmful. This is crucial for the health and well-being of the animals housed in the barn, as poor air quality can lead to respiratory issues and other health problems. Improving air quality ultimately contributes to better animal welfare and productivity.
