HAPPINESS IS IN THE FIELD: PREVENTING ATYPICAL MYOPATHY IN GRAZING HORSES WITH RATIONAL MANAGEMENT OF PASTURES AND HORSES DRAWN ON THE BASIS OF THE IDENTIFICATION OF RISK FACTORS FOR DISEASE - Agricultural Research Updates - page 161

C ONCLUSION
Prevention of AM is primordial since no specific therapy is available
against AM and supportive treatment often is unrewarding. Preventive
measures are determined based on descriptive data and on risk and protective
factors identified by statistical risk analysis. Specific countries, seasons and
climatic conditions are at risk for AM and parameters concerning the
signalement, horse management and pasture characteristics were previously
determined as risk or protective factor. Co-grazers of AM affected horses are
severely at risk to develop the condition (clinical or subclinical) and thus
demand special attention concerning prevention.
