Almost 250 delegates from 20 countries attended the 9th edition of the European Equine Health & Nutrition Congress (EEHNC). The 9th EEHNC was hosted by Utrecht University, the Netherlands (February 15-17). Internationally recognised specialists in nutrition, veterinary scientists, veterinarians, industry representatives and equine professionals attended this meeting. Participants could also follow precongress mini-symposia and practical hands-on workshops at the Faculty of Veterinary Medicine, Utrecht University. The congress theme was “Small things”, inspired by Van Gogh’s statement “For the great doesn’t happen through impulse alone and is a succession of little things that are brought together”. In the context of this theme ‘small things’ were represented amongst others by nutrients, microbiota, fungi, mycotoxins and dust particles. All these small things can have a big impact on a horse’s health.
