Summer Pasture-Associated Recurrent Airway Obstruction (SPARAO), often referred to as heaves or equine asthma, is one of the most significant chronic respiratory conditions affecting horses. While it can occur year round, a seasonal variation known as Summer Pasture-Associated Recurrent Airway Obstruction presents challenges during warmer months. For horse owners, understanding this condition is key to supporting their horses with effective and relevant solutions Jump to:What is SPARAO?Recognising the SignsSPARAO ManagementAdditional Respiratory SupportWhat is SPARAO?SPARAO is triggered by increased exposure to allergens commonly found in pastureenvironments during spring and summer. These include pollen from grasses and trees, airborne mould spores, and dust, all of which can cause hypersensitive reactions in affected horses. This immune overreaction results in inflammation, narrowing of the airways (broncho constriction), and mucus production, compromising the horses ability to breathe effectively.Recognising the SignsClinical signs of SPARAO vary in severity but typically include persistent coughing (often worse during or after exercise), nasal discharge, and laboured breathing. A visibleheave linemay develop along the horses abdominal muscles due to the increased effort required to exhale. Other signs include reduced performance, exercise intolerance, and, in chronic cases, a poor coat condition.Owners may not always associate these signs with pasture exposure, making education around this seasonal variant essential. A horse that performs well in winter may suddenly begin showing signs of respiratory stress when turned out during peak pollen times. Veterinary assessment is vital for accurate diagnosis. This often involves a clinical history, endoscopy, and diagnostic procedures such as broncho alveolar lavage (BAL),tracheal wash (TW) and blood tests. These help identify airway inflammation and exclude other potential causes. Treatment plans typically combine medical intervention with targeted management strategies.SPARAO ManagementManagement is the cornerstone of controlling SPARAO. Practical steps include:Limiting turnout during high pollen or dusty periodsProviding dust free forage, such as soaked or steamed hayAvoiding straw bedding and choosing low dust alternativesKeeping stables ventilated and cleanUsing air purifiers or misting systems to reduce airborne allergensModifying exercise regimes to avoid peak allergen timesWhile these steps help reduce allergen exposure, they can be difficult to implement consistently, particularly during dry, high risk periods.Additional Respiratory SupportAlongside the above recommendations and with veterinary assistance, it can also be beneficial to support your horses health during the summer with nutritional solutions. NAFs range of supplements can help horses breathe easier and perform at their best, even during the most challenging seasons.Consider adding NAF Easy Breathing in either a liquid or powder form, to your horses daily feed, a herbal support for the lungs. Or for more intense respiratory relief, NAF 5 Star Respirator Boost can be fed to help support both the lungs and immune system.
