Proper ventilation in barns plays a vital role in maintaining animal health by reducing humidity and ammonia levels. When ventilation is adequate, it helps to circulate fresh air throughout the barn while removing stale air. This process is essential in preventing the accumulation of moisture, which can lead to respiratory issues in livestock. High humidity levels can create an environment conducive to the growth of pathogens and mold, which negatively impact the health of the animals.

Additionally, ammonia is a compound that can be released from animal waste, and when it builds up in poorly ventilated barns, it can lead to respiratory irritation and other health concerns for livestock. Therefore, effective ventilation helps to mitigate these risks, ensuring that animals are housed in a healthier environment and are less prone to diseases related to poor air quality.
