How much a horse weighs under perfect health conditions can be determined by using the Henneke Body Scoring system. This is the most reliable method of evaluating how much subcutaneous fat exists across six main points on the animal’s body. This includes the neck area, withers, bach, behind the shoulder, tailhead and the ribs area. The system calls for the physical inspection of the horse and rate the body condition on a scale of 1 (extremely weak) to 9 (obese). Ideally, horses with a healthy weight should fall in the 4 to 6 range. Any score more or less then this, points at the need for immediate attention on the equine’s health.
