Nutritional management of muscle atrophy in an underweight horse with mild vitamin E deficiency and mild intestinal malabsorption

---

Abstract

Muscle atrophy in horses can develop insidiously, and often goes unnoticed until significant weight loss occurs. In this case report, the nutritional management is described of an eight-year-old underweight Ardennes draft gelding presenting with severe muscle atrophy, mild vitamin E deficiency, and mild intestinal malabsorption. Diagnostic evaluation revealed hypoalbuminemia, elevated muscle enzyme activity, and a moderate strongyle infestation. Despite an energy-adequate diet, progressive muscle loss persisted, highlighting the need for targeted nutritional intervention. A revised diet, incorporating high-quality forage, protein-rich feedstuffs, synthetic vitamin E supplementation via a roughage balancer, and anthelmintic treatment resulted in substantial weight gain (123kg) and improved muscle condition within five weeks. In this case, the critical role of tailored nutrition is underscored in equine muscle recovery and parasite management. Further research into the interplay between nutrient malabsorption, muscle atrophy and dietary strategies is warranted to optimize equine health outcomes.
