Atypical myopathy case studies
New information on the atypical myopathy (AM) disease, affecting grazing horses, is to be published, following 600 case studies.
Between 2006 and 2009, Dr Gaby Van Galen and her colleagues studied cases reported to the Atypical Myopathy Alert Group across Europe. Their findings are to be published in the next issue of Equine Veterinary Journal by the British Equine Veterinary Association (BEVA).
Out of 600 reported AM cases, 354 were identified. Overall survival of the disease is a low 26 percent, with successful cases including those that remained standing and antioxidant therapy.
It is not yet known what causes the disease, which has been recognised since 1984 and appears during the spring and/or autumn; however, risk factors include the presence of dead leaves, sloping pastures and full-time pasture access, to name a few.
