Equine Malnutrition Study Guide
Overview and Clinical Importance
Malnutrition in horses encompasses a spectrum of nutritional disorders ranging from simple energy deficits to complex vitamin and mineral imbalances. Understanding equine malnutrition is essential for the NAVLE because it represents a common clinical presentation with potentially life-threatening complications, particularly during rehabilitation. This topic integrates knowledge of equine physiology, nutrition, metabolism, and emergency medicine.
Malnutrition may result from inadequate feed intake, poor-quality feed, malabsorption syndromes, chronic disease states, dental abnormalities, parasitism, or neglect. The multisystemic nature of malnutrition affects virtually every organ system, making it a high-yield topic for board examinations.
Body Condition Scoring: The Henneke System
The Henneke Body Condition Scoring (BCS) system is the standardized method for assessing equine body fat. Developed by Don Henneke at Texas A&M University in 1983, this system uses a 1-9 scale based on visual appraisal and palpation of fat deposits at six anatomical locations: neck, withers, behind the shoulder, ribs, loin, and tailhead.
