In the mitochondria, complexes I and III of the electron transport system (ETS) generate reactive oxygen species (ROS) during exercise that are reduced by antioxidants to mitigate oxidative stress. Among these antioxidants are thiol-based antioxidants such as glutathione as well as coenzyme Q10 (CoQ10), which also transports electrons from complex I and II to complex […]

In combination with exercise, nutrition is an essential component of managing horses with myopathies. The optimal feeding program for an individual is tailored to the diagnosis of a specific underlying myopathy. Exertional myopathies are defined by muscle pain and impaired performance during or after exercise. Exertional rhabdomyolysis (ER) represents a subset of exertional myopathies characterized […]

Assembled by the nutritionists and veterinarians at Kentucky Equine Research (KER), this easy-to-use guide includes practical feeding and management recommendations for the following diseases: Pituitary pars intermedia dysfunction (PPID) Equine metabolic syndrome (EMS) Exertional rhabdomyolysis (RER) Polysaccharide storage myopathy (PSSM) Malignant hyperthermia (MH) Hyperkalemic periodic paralysis (HYPP)

To determine the effect of dietary starch, bicarbonate, and fat content on metabolic responses and serum creatine kinase (CK) activity in exercising Thoroughbreds with recurrent exertional rhabdomyolysis (RER), 5 RER horses were fed 3 isocaloric diets (28.8 Mcal/d [120.5 MJ/d]) for 3 weeks in a crossover design and exercised for 30 minutes on a treadmill 5 days/wk.

To determine whether plasma, urine, and fecal electrolyte and mineral concentrations differ between clinically normal horses and Thoroughbreds with recurrent exertional rhabdomyolysis (RER) after consumption of diets varying in cation-anion balance.

Previous studies have associated recurrent exertional rhabdomyolysis (RER) with a diet high in soluble carbohydrate (CHO). The purpose of this study was to investigate the effect of 3 diets on clinical and metabolic parameters in 5 Thoroughbred horses with RER and 3 healthy Thoroughbreds performing a standardised exercise test (SET). Two diets were formulated to meet energy requirements for the amount of exercise being performed in the form of CHO or fat (21.4 Mcal DE/day).
