In combination with exercise, nutrition is an essential component of managing horses with myopathies. The optimal feeding program for an individual horse is tailored to the diagnosis of a specific underlying myopathy.
The key points of this article include:
- Horses with exertional rhabdomyolysis caused by types 1 and 2 polysaccharide storage myopathy (PSSM1 and PSSM2-ER) benefit from low nonstructural carbohydrate (NSC) diets and supplementary fat as a metabolizable form of energy.
- Horses with recurrent exertional rhabdomyolysis can be managed by lowering NSC, but not to the extreme of PSSM, and then replacing needed calories with fat.
- Arabian horses with myofibrillar myopathy (MFM-ER) can be managed with moderate NSC, supplementary fat, amino acids, and antioxidants N-acetylcysteine and coenzyme Q10.
- Warmblood horses with MFM benefit from a similar diet to MFM-ER horses but with less additional fat.
