Pollen Allergy in Horses: Causes, Symptoms and Pollen Calendar

Everything About Pollen Allergies in Horses

Causes of Pollen Allergies in Horses

Horses can be allergic to various types of pollen, including that of grasses, trees, and weeds. When a horse comes into contact with these allergens, the immune system may exhibit an excessive reaction, releasing specific antibodies that trigger an allergic response.

Symptoms of Pollen Allergy in Horses

1. Coughing

A dry or allergic cough is one of the most common symptoms. The horse may start coughing during or after exercise or under certain weather conditions.

2. Nostril discharge:

Watery or mucus-like nasal discharge can occur, making breathing difficult and leading to increased sneezing.

3. Difficulty Breathing:

Horses with pollen allergies may be susceptible to respiratory difficulties, breathing faster, laboured breathing or wheezing.

4. Itchiness:

Some horses with pollen allergies may develop itchiness, resulting in increased head shaking, rubbing against objects, or scratching the body.

What to Do in Case of Pollen Allergies?

1. Identification of allergens:

The first step in managing pollen allergies is to identify the specific allergens to which the horse reacts. This can be done through skin tests or blood examinations. A veterinarian can assist in determining the allergens.

2. Pollen Radar:

Tracking pollen levels, minimises the exposure for affected horses. It shows the times and types of pollen that are most prevalent in a particular region. A pollen radar can help adjust outdoor activities accordingly and keep the horse in protected areas when specific pollen levels are high.

3. Environmental management:

Creating an allergen-free environment for the horse is crucial. This may involve removing allergy-triggering plants near the stable, limiting pasture time during peak pollen periods, and maintaining a clean and dust-free stable.

4. Medications and therapy:

In severe cases of pollen allergy, veterinarians may prescribe medications such as antihistamines or corticosteroids to alleviate symptoms. Immunotherapy, where the horse is gradually exposed to increasing amounts of allergenic substances, can also be an option. Including a pollen season, which displays the times and types of pollen in a specific region, can help monitor the pollen exposure for allergic horses and facilitate allergy management. Below is an example of a pollen season:
