Proper ventilation in animal rooms is essential primarily to prevent the accumulation of waste gases, which can be detrimental to the health and well-being of the animals housed within these environments. Waste gases, such as ammonia and carbon dioxide, can result from animal excreta and can significantly impact air quality. High levels of these gases can lead to respiratory issues, stress, and overall poor health in the animals, which can hinder research outcomes and the animals' quality of life.

While reducing noise levels can contribute to a positive environment, it is not the primary function of ventilation. Enhancing animal growth and maintaining animal color are more related to factors such as nutrition, genetics, and environmental conditions rather than directly influenced by ventilation systems. Thus, the main purpose of proper ventilation is to ensure a clean, breathable atmosphere by effectively managing waste gases and maintaining safe air quality for the animals.
