Effect of the administration of a nutraceutical supplement in racehorses
Study finds beneficial effects on lower airway inflammation
Results showed the beneficial effect of the supplement on mild-moderate lower airway inflammation
Mild-moderate equine asthma (MEA) is a chronic inflammatory disorder of the lower airways of the horse, characterized by tracheal mucus accumulation, cough and deficient performance. The therapeutic approach is based on pharmacological treatment and environmental management. Moreover, the efficacy of the administration of antioxidant molecules has been reported in other studies. The aim of the present study was to evaluate the effect of the administration of a commercial nutraceutical supplement, composed of herbal extracts, on lower airway inflammation in racehorses.
Twelve thoroughbreds affected by MEA were selected for this study. All horses underwent a clinical examination with assignment of a clinical score, airway endoscopy and cytological examination of bronchoalveolar lavage fluid. In seven horses, the supplement was administered for 21 days in association with environmental changes, while in five horses only environmental changes were performed. All procedures were repeated by the researchers at the end of the study. Data concerning the clinical score, the endoscopic scores and the cytology at the beginning and at the end of the study were compared as part of the research.
Data showed a significant reduction (p < 0.0156) of the clinical score and a significant reduction (p < 0.0156) of the tracheal mucus score.
In conclusion, the results showed the beneficial effect of the supplement on mild-moderate lower airway inflammation, due to its antioxidant activity.
