PMID 42278060 — The Role of Omega-3 Fatty Acids in Horses' Nutrition-A Review. (Animals : an open access journal from MDPI, 2026). Abstract (opening): This narrative review presents examples of omega-3 fatty acids supplementation in horse nutrition. Fats are essential in equine nutrition, serving not only as an energy source but \n2. PMID 40923556 — Steamed hay for the prevention of severe equine asthma exacerbations. (Equine veterinary journal, 2026). Abstract (opening): Steaming hay reduces respirable particles and is commonly used to feed horses with asthma. However, it showed inconsistent benefits in clinical studies. (1) To assess the effects o\n3. PMID 41187975 — Field-applicable low-intensity exercise induces bronchodilation in horses with severe asthma. (Equine veterinary journal, 2025). Abstract (opening): Airway dysfunction in severe equine asthma (SEA) often results in early retirement or euthanasia of affected horses. Exercise-induced bronchodilation occurs in horses with SEA afte\n4. PMID 42207732 — ASTHMA PHENOTYPES AND COMORBID DISEASES. (International archives of allergy and immunology, 2026).
