Chronic lower airway diseases, such as recurrent airway obstruction (RAO) and inflammatory airway disease (IAD), are all too common in horses today. Reducing dust in the diet and environment can benefit these horses, but Purdue University researchers found that omega-3 fatty acid supplementation will reduce signs even further.

For the purpose of their study, the researchers used an algae-based omega-3 supplement that also contained vitamin C, methylsulfonylmethane (MSM), and a mushroom complex.

ACVIM, a professor in the Purdue University Department of Veterinary Clinical Sciences, in West Lafayette, Indiana.

Specifically, the team aimed to evaluate the algae supplement’s impact on horses with RAO or IAD housed in a low-dust environment, based on changes in visual analog scores (VAS) for cough, lung function, and bronchoalveolar lavage fluid (BALF)
