Which statement best describes a key function of ventilation in livestock buildings?

• A. Water quality
• B. Disease and parasites
• C. Temperature and humidity
• D. Light and feed intake

Answer: (C)

Ventilation’s main job is to regulate the air environment in livestock buildings, especially temperature and humidity. By exchanging stale air for fresh air, it helps remove excess heat and moisture, preventing heat stress and condensation that can worsen respiratory conditions and reduce performance. Clean, well-humidified air also lowers the buildup of harmful gases and dust that can affect health. While good air flow can influence disease risk and overall air quality, water quality, lighting, and feed intake are controlled by other systems and management practices, not by ventilation itself.
