For its 8th edition, the European Workshop on Equine Nutrition will once again bring you the latest research in horse nutrition and health.

A special focus will be offered on gut microbiology and its relation to health, welfare and performance.

Dijon being a world leader center in taste and sensory science, EWEN will also present an innovative approach to horse feeding preferences.
