USE OF CLINICAL MEASUREMENTS TO PREDICT THE OUTCOME IN CHRONIC CASES OF GRASS SICKNESS (EQUINE DYSAUTONOMIA)

Forty-five cases of chronic grass sickness were given scores for selec ted clinical measurements when they were first examined, to assess the ir value in predicting survival. Sixteen cases survived. The clinical scores for the degree of dysphagia, appetite, colic and the degree of reduction in gut sounds were significantly lower in the survivors than in the non-survivors. In addition, only the non-survivors had severe rhinitis. Ponies were significantly less likely to survive than cob ty pes.
