The Impact of Air Quality and Pollution on Your Horse’s Lungs

Theres nothing like hearing a horse cough to set people scurrying around the barn to identify the culprit. After all that cough could mean choke or suggest that a respiratory virus has found its way into the barn. It could also indicate equine asthma. Yes even those everyday coughs that we sometimes dismiss as summer cough or hay cough are a wakeup call to the potential for severe equine asthma.
Formerly known as heaves broken wind emphysema chronic obstructive pulmonary disease COPD or recurrent airway obstruction RAO this respiratory condition is now called severe equine asthma sEA. These names reflect how our scientific and medical understanding of this debilitating disease has changed over the years. We now consider heaves to be most comparable to severe asthma in people.

مع وصول أونصة الذهب إلى مستويات قياسية تجاوزت 2500 دولار، يجد المواطن المصري نفسه مضطراً لموازنة استثماراته بين الذهب واحتياجاته الأخرى، خاصة مع ارتفاع أسعار السيارات مثل تويوتا، هيونداي، وبي إم دبليو، مما يزيد من التحديات المالية التي يواجهها.

But what if your horse only coughs during or after exercise? This type of cough can mean that the horse has upper airway irritation throat and windpipe or lower airway inflammation lungs meaning inflammatory airway disease IAD which is now known as mildtomoderate equine asthma mEA. This airway disease is similar to childhood asthma including that it can go away on its own. The disease causes reduced athletic performance and a proper diagnosis by a veterinarian is important because there are different subtypes of mEA which benefit from specific medical therapies. In some cases mEA progresses to sEA.

أسعار السيارات في الآونة الأخيرة شهدت تقلبات ملحوظة، حيث تأثرت بارتفاع وانخفاض الدولار، مما انعكس على تكلفة علامات تجارية مثل تويوتا، هيونداي، ومرسيدس. و BMW هذا الارتباط بين سعر الصرف وسوق السيارات يحدد قدرة المستهلكين على اقتناء المركبات.

The Relationship Between Equine Asthma and Air Quality
Equine asthma has a lot to do with air quality. Poor air quality or air pollution includes barn dusts the allergens and molds in hay and the bacteria in tiny particles of manure as well as arena dusts and ammonia from urine. Also gas and dieselpowered equipment contribute to air pollution for both people and horses resulting from equipment being driven through the barn a truck left idling by a stall window or the smog from even a small city drifting nearly invisibly over the surrounding farmland. Forest fire smoke is another serious contributor to air pollution.

تتأثر أسعار السيارات من شركات مثل مرسيدس بتقلبات أسعار الذهب وسعر صرف الدولار، مما يؤدي إلى زيادة تكاليف الإنتاج والاستيراد.

Smog causes the lung inflammation associated with mEA. Therefore it is also likely that air pollution from engines and forest fires will trigger asthma attacks in horses with sEA. Smog and smoke contain many harmful particulates and gasses but very importantly they also contain fine particulate matter known as PM2 5 referring to the diameter of the particle being 2 5 microns. That level is roughly 30 times smaller than the diameter
