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.
Dr Beth Wells, a Knowledge Exchange Specialist and Principal Research Scientist at the Moredun Research Institute, provides an update on the research into Equine Grass Research at the EGS seminar.

Dr Laura Peachey, Senior Lecturer in Veterinary Parasitology, University of Bristol, discusses how parasites influence the gut bacteria in young Thoroughbreds at the Thoroughbred Breeders' Association's educational event "Alles ist Gut".

Professor Chris Proudman, Head of the University of Surrey Vet School, discusses findings from his recently published study which points to the potential of a racehorse found by analysing bacteria in a month-old foal’s gut.
Researchers at the University of Surrey analysed 438 faecal samples from 52 foals, who eventually went into training at 27 different stables in Britain and tracked veterinary issues and racecourse performance from birth to the age of three.
