What Is The Most Common Cause Of Recurrent Obstructive Pulmonary Disease In Horses?

As previously mentioned, the most common triggers for RAO are organic dusts, mold, and endotoxin present in hay and straw. Round bale hay is high in endotoxin and organic dust content, and the presence of round bale hay is a potential cause of treatment failure in horses on pasture.

What causes COPD in horses?

The horse’s immune system responds to the particles causing constriction of the airway and increased secretion of thick mucous.

What is recurrent airway obstruction horses?

What is recurrent airway obstruction (RAO) in the horse? RAO, also known as heaves, broken wind, and chronic airway reactivity, is a common respiratory disease of horses characterized by airway narrowing (bronchoconstriction), mucus production, and bronchospasm.

What causes Rao in horses?

RAO is a disease of the smaller airways (bronchioles) of the lungs and is caused by an allergy to small dust particles and spores that are inhaled by the horse when it breathes. Fungal spores and/or pollen are most important in terms of allergic ‘trigger’ factors.

Is COPD common in horses?

COPD is an allergic reaction to certain otherwise innocuous substances – allergens. These allergens are typically dust, mould and fungal spores (e.g. Aspergillus). It is therefore most common in horses fed hay and bedded on straw. It is similar to asthma and farmer’s lung in humans.

What is the best treatment for horses with COPD?

However, horses with moderate to severe signs of COPD will also require medical treatment, at least initially. Treatment will often involve combined use of bronchodilator and corticosteroid drugs.

How do you treat recurrent airway obstruction in horses?

Systemic corticosteroids and aerosolized bronchodilators are the most immediately helpful therapy for a horse in respiratory distress. Intravenous administration of Dexamethasone should improve lung function within 2 hours of administration.

Can a horse live with EIA?

Horses that survive the acute phase of infection become lifelong carriers that pose a transmission risk to other horses. EIA-positive horses must be identified and isolated (at least 200 yards) from other horses or euthanized to prevent the spread of the virus.

Is EIA in horses contagious?

Infected horses, whether showing symptoms or not, remain chronically infected with EIA virus and their blood remains infectious to other horses for the remainder of their lives. This means that the horse is a persistent viremic carrier and can potentially transmit the infection to other horses.

What is the most common GIT disorder of horses?

gastric ulcers
The most commonly described intestinal disease in horses is probably gastric ulcers and colic but other diseases such as colitis and inflammatory bowel disease also play an important role. The article describes selected recent developments in aetiology, diagnosis and treatment of equine gastrointestinal diseases.

How do you treat Rao in horses?

Horses with mild to moderate airway inflammation can be treated with aerosolized corticosteroids and aerosolized or systemic (clenbuterol) bronchodilators.

Can IAD in horses be cured?

What is the prognosis for a horse with IAD? The prognosis for full recovery is good with most horses with IAD responding well to management changes aimed at decreasing exposure to irritants, but signs of improvement may take one to two months. Treatment with anti-inflammatories and bronchodilators will speed recovery.

What are the 3 causes of COPD?

Risk factors for COPD include:

• Exposure to tobacco smoke. The most significant risk factor for COPD is long-term cigarette smoking.
