By Mark Andrews - It's not just horseback riders that cough and wheeze at this time of year. Respiratory problems are common in horses as well. Loss of performance may be the first sign that something is wrong. Mildly affected animals may cough occasionally when eating or when starting work. As the condition gets worse they may cough almost continuously.

Horses are more likely to suffer from laminitis in the fall than at any other time of year. Two reasons are the high NSC (non-structural carbohydrates) from cooler nighttime temperatures and increased blood ACTH (adrenocorticotropic hormone) secretion from the pituitary gland. Both of these lead to elevated insulin.

Adults with asthma struggle to breathe when they are exposed to dust and allergens. They can exhale without too much difficulty, but their inflamed lungs with narrowed airways make it hard to inhale enough oxygen, and the mucus in their airways leads to coughing.

Causes, Prevention and Treatment - Gastric ulcers in horses are far more common than many people realize. The condition is very often found in horses kept in stalls, frequently trailered, or undergoing intensive training. The associated anxiety, in addition to artificial and controlled feeding routines alien to a horse’s natural grazing patterns, may put the animal under varying levels of stress.

As horse owners, we are entirely responsible for maintaining the health, safety, and well-being of our animals. This includes protecting our horses against the diseases that have the potential to cause them pain, suffering, or even death. One of the most effective ways that an owner can guard their horse against such a fate is by ensuring an appropriate vaccination program. In the words of Benjamin Franklin, “An ounce of prevention is worth a pound of cure.”

Western College of Veterinary Medicine WCVM horse bacteria equine asthma, equine chronic obstructive pulmonary disease (COPD), horse heaves

Veterinary researchers at the Western College of Veterinary Medicine (WCVM) in Saskatoon, Saskatchewan are investigating whether certain bacterial populations in a horse’s windpipe can contribute to RAO, or heaves. Motivated by human research on asthma and chronic obstructive pulmonary disease (COPD), large animal internal medicine specialist Dr. Katharina Lohmann has developed the airway microbiome project.

horse heaves, equine heaves, horse lungs, equine lung disease

Heaves is a chronic, non-infectious lung disease that primarily affects mature horses and can have a significant effect on a horse’s well-being and performance ability. Heaves is also referred to as recurrent airway obstruction (RAO) and is often compared to human asthma. The primary pathologic mechanisms leading to clinical signs in affected horses are bronchospasm, inflammation and thickening of the lower airways (small bronchi), and accumulation of mucus and inflammatory exudates in the airway lumen. The term RAO indicates that the disease is chronic and recurrent, although “remission” from clinical signs can be achieved through treatment and proper management of affected horses.
