Titel
Gewässertes Heu, bedampftes Heu oder Heulage bei equinem Asthma – und was ist dran am schlechten Ruf der Heulage?
Beschreibung
Equines Asthma ist die häufigste chronische Atemwegserkrankung des adulten Pferdes. In dieser Folge des Podcasts Equine Vet News sprechen Dr. Anja Gabe und Dr. Caroline Wirth über die aktuelle Studienlage zu drei Raufutter-Alternativen – bedampftem, gewässertem Heu und Heulage – und deren Wirkung auf Klinik, Lungenfunktion und Atemwegsentzündung bei Pferden mit equinem Asthma. Im letzten Teil des Podcasts diskutieren Dr. Anja Gabe und Dr. Caroline Wirth die im Internet und in der Praxis beschriebenen negativen Auswirkungen von Heulage, wie zum Beispiel Botulismus, Dysbiose, Übersäuerung, Hufrehe und Karies, auf Grundlage veröffentlichter Studienergebnisse zu diesen Themen.
In dieser Folge werden vier aktuelle Studien detailliert vorgestellt:
Steamed hay for the prevention of severe equine asthma exacerbations; Raïsky C et al. 2026. Equine Veterinary Journal. – Steamed hay and alfalfa pellets for the management of severe equine asthma; Symoens A et al. 2025. Equine Veterinary Journal.- Effects of soaked hay on lung function and airway inflammation in horses with severe asthma, Westerfeld R et al. 2024. Journal of Veterinary Internal Medicine. – Effects of low-dust forages on dust exposure, airway cytology, and plasma omega-3 concentrations in Thoroughbred racehorses: A randomized Clinical trial; Olave CJ et al. 2023. Journal of Veterinary Internal Medicine.
