Equine Grass Sickness is a disease of horses, ponies and donkeys in which there is damage to parts of the nervous system which control involuntary functions, producing the main symptom of gut paralysis.
In December 2025 a seminar took place in Newmarket, supported by the National Stud, the TBA, Rossdales and Saracen Horse Feeds where speakers updated breeders on the latest research into this devastating disease which not only has a detrimental impact on horse welfare individually and collectively, but also on businesses, land and property values.
Professor Lee Innes and Anne Logan discuss what's being done around the research into EGS to advance understanding of the disease, improve treatment options and reduce incidents of the disease.
