EQUINE GRASS SICKNESS
Equine grass sickness (EGS) is a debilitating and predominantly fatal disease affecting grazing horses, ponies and donkeys, which was first described in eastern Scotland in the early 1900s. The disease affects the nervous system that controls involuntary functions, (the autonomic nervous system) and most clinical signs are attributable to nerve damage within the horse’s gastrointestinal tract. Despite more than a century of research in to the condition, we do not know definitively what causes EGS. There is increasing scientific evidence indicating that the bacterium Clostridium botulinum may be the cause of EGS, and it is likely that multiple factors are involved, with pasture-associated or dietary risk factors also playing a role in causing the disease.
