What is a known effect of ammonia on horses?

Ammonia is a harmful gas that can have severe negative effects on equine health, particularly affecting the respiratory system. Exposure to ammonia in the environment, such as in poorly ventilated stalls or areas with excessive waste, can irritate the mucous membranes in the respiratory tract of horses. This irritation can lead to chronic respiratory problems, decreased lung function, and a higher susceptibility to infections and other serious health conditions.

Maintaining a clean and well-ventilated environment is critical in equine care to minimize ammonia exposure. The presence of ammonia in the air is particularly concerning because it can exacerbate any existing respiratory issues such as heaves or chronic obstructive pulmonary disease (COPD) in horses. Therefore, understanding the detrimental effects of ammonia is essential for the management of equine health and welfare.
