Recurrent Exertional Rhabdomyolysis
Chronic Exertional Rhabdomyolysis
Recurrent Exertional Rhabdomyolysis (RER) is one of the most common muscle disorders in horses, affecting over 10% of Thoroughbred racehorses; 75% of these horses having monthly tying-up episodes.
Results from a clinical trial conducted by the University of Minnesota, and research studies showed evidence that a horse's susceptibility to RER is inherited as an autosomal dominant trait; caused by an abnormality in intracellular calcium regulation.
Diet: Feed horses a low sugar, low starch (NSC) grain with plenty of high quality hay. If needed, such as for performance horses, extra energy can be obtained by fat supplementation, in order to increase their carbohydrate intake.
Activity level: Ensure horses have daily turnout and consistent exercise.
Minimize stress and excitability: Turn out, feed, or exercising RER horses before other horses and providing pasture mates for comfort
Do not over supplement horses with more than the recommended amount of selenium in their diet
