The chart covers six major parts of the horse; neck; withers, (where the neck ends and the back begins) the shoulder area; ribs, loins, and the tailhead area. The chart rates the horses on a scale of 1 to 9. A score of 1 is considered poor or emaciated with no body fat. A nine is extremely fat or obese. A horse that is rated a 1 on the Henneke Chart is often described as a walking skeleton and is in real danger of dying. Courts in the
Observers are trained to visually inspect the horse and also to palpate each part of the horse with their hands to feel for body fat. The observer then assigns each area of the body the numerical score that corresponds with the horse's condition. When a horse has a long haircoat it is imperative that the person scoring the horse use their hands to feel the horse. The horse's long haircoat will hide the protrusion of bones, all except in the most extreme cases.
The scores from each area are then totaled and divided by 6. The resulting number is the horse's rating on the Henneke Body Scoring Condition Chart.
People working in this field will refer to the horse as being a "1 on the Henneke" or a "3 on the Henneke". The Henneke Chart is a standardized scoring system, whereas the terms, "skinny", "thin", "emaciated", or "fat" are all subjective terms that have different meanings to different people.
Defense attorneys cross examining veterinarians and horse experts argue that the chart is not scientific. As one full time equine vet stated, "No it is not scientific, but it is as close as we are going to get."
The Henneke Body Scoring Condition Chart is readily available. The chart is printed on the back of several manufacturer's of horse feed products and is available on numerous universities web sites. The chart has been used in several leading national horse magazines.
Conformational differences between horses may make certain criteria within each score difficult to apply to every animal. In these instances, those areas influenced by conformation should be discounted, but not ignored when determining the condition score.
Conformation also changes in pregnant mares as they approach parturition (birth). Since the weight of the concept us tends to pull the skin and musculature tighter over the back and ribs, emphasis is placed upon fat deposition behind the shoulder, around the tailhead and along the neck and withers in these cases.
Emaciated. Prominent spinous processes, ribs, tailhead and hooks and pins. Noticeable bone structure on withers, shoulders and neck. No fatty tissues can be palpated.
Emaciated. Slight fat covering over base of spinous processes. Transverse processes of lumbar vertebrae feel rounded. Prominent spinous processes, ribs, tailhead and hooks and pins. Withers, shoulders and neck structures faintly discernible.
Fat built up about halfway on spinous processes, transverse processes cannot be felt. Slight fat cover over ribs. Spinous processes and ribs easily discernible. Tailhead prominent, but individual vertebrae cannot be visually identified. Hook bones appear rounded, but easily discernible. Pin bones not distinguishable. Withers, shoulders and neck accentuated.
Negative crease along back. Faint outline of ribs discernible. Tailhead prominence depends on conformation, fat can be felt around it. Hook bones not discernible. Withers, shoulders and neck not obviously thin.
Back is level. Ribs cannot be visually distinguished, but can be easily felt. Fat around tailhead beginning to feel spongy. Withers appear rounded over spinous processes. Shoulders and neck blend smoothly into body.
May have slight crease down back. Fat over ribs feels spongy. Fat around tailhead feels soft. Fat beginning to be deposited along the sides of the withers, behind the shoulders and along the sides of the neck.
May have crease down back. Individual ribs can be felt, but noticeable filling between ribs with fat. Fat around tailhead is soft. Fat deposits along withers, behind shoulders and along the neck.
Crease down back. Difficult to palpate ribs. Fat around tailhead very soft. Area along withers filled with fat. Area behind shoulder filled in flush. Noticeable thickening of neck. Fat deposited along inner buttocks.
Obvious crease down back. Patchy fat appearing over ribs. Bulging fat around tailhead, along withers, behind shoulders and along neck. Fat along inner buttocks may rub together. Flank filled in flush.
