Respiratory Problems
Respiratory problems are second only to lameness as a leading cause of poor
performance in horses. The respiratory system provides the vital function of
supplying oxygen to the blood that then provides energy to the rest of the body.
It also acts to expel waste in the form of carbon dioxide and defends the body
from antigens (germs) or allergens that cause harm to the body and lungs. The
respiratory system is constantly being exposed to infectious agents (viruses,
bacteria, fungi) and noxious stimuli (pollen, dust, ammonia) with every breath.
Though sometimes not evident, respiratory problems can prevent your horse
from performing at their best. If respiratory problems arise and go untreated
they can develop into more serious chronic problems that can cause permanent
changes to the horse’s airway and become difficult to treat.
The most common respiratory diseases in performance horses are due to
viruses, such as influenza and herpes (rhino) and noninfectious diseases such as
heaves and inflammatory airway disease. We recommend vaccinating your horse to
help prevent against influenza and rhino. Heaves is often referred to as chronic
obstructive pulmonary disease (COPD). It is described as equine asthma and
affects older horses (7 years of age and older). These horses appear to be very
sensitive to organic particles that are present in feed and bedding. They often
have increased respiratory rates at rest, varying degrees of respiratory
difficulty, labored breathing, coughing, as well as exercise, heat, and humidity
intolerance. Inflammatory airway
disease (IAD) is different than heaves in that it is thought to be associated
with continuous exposure to high levels of inhaled particles. These particles
include plant fragments, insect parts, dust, pollen, and mold spores that are
common in stall and stable environments. The exposure to these irritants can
cause inflammation and bronchospasms
along with increased production of mucous.
This decreases the airways ability to expel foreign particles and can
cause the airway to become more sensitive to irritation. If IAD goes untreated,
with time, permanent changes to the linings of the lower airways can be
impossible to reverse. If you
suspect that your horse may have some respiratory problems be sure to contact
your Vet so that it can be properly diagnosed and treated.
Respiratory disorders are very manageable and may be vital to the ability
of your horse to perform at its best.
