What is a recommended initial management approach for PSSM Type 1?

• A. Diet and exercise modifications
• B. Surgery
• C. High-fat diet
• D. Vaccination

Answer: (A)

PSSM Type 1 is a metabolic muscle disorder in horses, where altering the energy source the muscles rely on is the key to reducing episodes of muscle stiffness and damage. The recommended initial approach focuses on diet and conditioning because these directly influence glycogen storage and muscle fuel use. Reducing starch intake lowers the glucose substrate driving glycogen accumulation in muscles, while increasing fat as the primary energy source provides a steady, more energy-efficient fuel for workouts. Regular, moderate exercise helps improve muscle oxidative capacity and conditioning, reducing the risk of tying up during exertion. So starting with diet and exercise modifications addresses the underlying energy balance issue without invasive procedures or irrelevant measures. A high-fat diet is part of the dietary strategy, but the first step is the overall plan of adjusting both diet and exercise. Surgery and vaccination do not address this metabolic problem and aren’t part of the initial management.
