Feeding and supplementation of riding horses with myopathy symptoms
Abstract
Chronic exertional myopathies occur in many breeds worldwide and have a tremendous
negative impact on performance in affected horses. In Warmbloods, myofibrillar myopathy
(PSSM2/MFM) is a newly described disease thought to represent a subset of the
Polysaccharide Type 2 Storage Myopathy. Lack of amylase-resistant polysaccharide storage
was however recently brought to light for PSSM2/MFM, changing the perception of the
disease to protein oxidative and post exercise maladaptive pathophysiologic events. Feeding
strategies and their effects on Warmblood horses suspected to suffer from chronic
myopathies have not been performed so far.
