Equine Grass Sickness - Welfare and Management

Understanding equine grass sickness (equine dysautonomia), its welfare impacts, and management of chronic cases.

Key Facts

Equine grass sickness (EGS) affects horses, ponies, and donkeys primarily on pasture in Britain
The disease destroys neurons of the autonomic nervous system causing progressive gastrointestinal failure
Acute EGS is invariably fatal and requires rapid euthanasia; chronic EGS has a survival rate of approximately 50%
Nursing care for chronic EGS survivors is intensive requiring hand-feeding, slings, and 24-hour supervision
Pasture management including avoiding high-risk fields in spring significantly reduces incidence
