 Rhabdomyolysis is recognized in horses . Horses can develop a number of muscle disorders , many of which may progress to rhabdomyolysis . Of these , some cause isolated attacks of rhabdomyolysis ( e.g. , dietary deficiency in vitamin E and selenium , poisoning associated with pasture or agricultural poisons such as organophosphates ) , while others predispose to exertional rhabdomyolysis ( e.g. , the hereditary condition equine polysaccharide storage myopathy ) . 5 – 10 % of thoroughbred horses and some <unk> horses suffer from the condition equine exertional rhabdomyolysis ; no specific cause has been identified , but an underlying muscle calcium regulation disorder is suspected .
