EQUINE GRASS SICKNESS.

Equine grass sickness is fatal condition in horses on pasture, the condition results in colic and prognosis is guarded.The condition affects all age groups,can occur at any time but very common in wet conditions/seasons. The cause of the condition has been pinned as Clostridium botulinum,this bacteria lives in moist soil and when it spreads on grass its eaten by the horse,resulting in severe poisoning. The bacteria toxins affect the horses's intestinal tract which affects the nerves causing a dysfunction resulting in severe colic. The onset of the equine grass sickness could be per acute, acute and chronic.In per acute cases the horses are found dead.The prognosis in the chronic and acute cases are guarded. The acute case, the onset is sudden, with severe abdominal discomfort, high pulse rate and restlessness. The treatment is colic surgery.While the chronic case ,the horse slowly develops a persistent low grade colic with rapid weight loss.The upper eye lid is droopy and there is sticky nasal discharge, and fecal balls are hard and small.The treatment is pain relief and supportive therapy. Equine grass sickness can be prevented with pasture identification; if an area has record of such sickness avoid letting horses in area.Where there has been recent work lately, that involves soil works or turning should be avoided.Areas where dead animals are commonly found in pasture should be avoided.Horses that do not depend solely on grasses for nutrition hardly come down with grass sickness,thus feeding hay at pasture and bringing horses in to stable at night may help reduce its occurrence.
