Visually and by palpation at six points: neck, behind the shoulder, ribs, back line, hip and tail head. Vet gives the most precise estimate.

What role does the sharer have on BCS?

She sees the horse regularly and can spot changes early. Factual report to owner. Diagnosis and therapy remain with the vet.

Body Condition Score (BCS) in horses explained: understanding the 1 to 9 scale

3 min read

The BCS is a standardized method to assess a horse's nutritional state objectively. Instead of subjective "a bit thin" or "a bit fat", you classify on a 1 to 9 scale. This guide explains the Henneke scale, what the sharer can do with it and the clear boundary to veterinary diagnosis.

This guide stays structural

How to read BCS, palpate precisely and what BCS target for which horse are medical decisions. This guide gives the framework, not individual recommendations. The vet remains the contact for target BCS for a specific horse (GST, SVPM).

The Henneke scale 1 to 9

Developed in the 1980s, today international standard. From 1 (very thin) to 9 (extremely obese).

1 to 3: Underweight to very thin. Ribs, hips and vertebrae visible. Disease suspicion.
4 to 5: Lower half of ideal. Ribs barely visible, vertebrae not protruding.
5 to 6: Ideal range for most leisure and sport horses.
7: A bit too fat. Ribs not palpable without pressure, deposits at neck and tail head.
8 to 9: Obese to extremely obese. Significant deposits. Higher health risk.

Target BCS depends on breed, age, use and life phase.

The six evaluation points

Neck and crest. At low BCS, neck thin. At high, thick crest.
Behind the shoulder. Transition to ribs.
Ribs. At BCS 4 barely visible, at 5 palpable, at 7 only with pressure.
Back line. At low, spine visible. At high, broad and flat.
Hips and pelvis. At low, bony protruding. At high, blurred.
Tail head. Deposits indicate high BCS.

Precise evaluation requires experience. Vets and nutritionists determine accurately.

What the sharer can do with BCS

BCS isn't a diagnostic tool for the sharer. It's an observation frame.

Spot changes. Whoever sees the horse regularly notices over weeks and months.
Factual communication to owner. Without judgment, without diagnosis.
Regular photos. One BCS photo per season makes changes visible without guessing.

See Shared care checklist for structured observation.

Why BCS matters in Switzerland

Energetic Swiss pastures. May to July, much energy, especially after rain. Horses too long on these pastures gain quickly (see Horse in summer).
Swiss ponies and rustic breeds genetically tend to fat gain.
Senior horses often lose muscle and look thin while fat cover is normal.
Sport horses. In active training, BCS often at the lower ideal.

FSVO cites nutritional state as an indicator of compliant keeping.

Reacting to a BCS change

Reaction is structural, not therapeutic.

Inform owner with date and observed points, ideally photo.
Vet on dramatic change. Rapid loss (one point in two weeks) can indicate illness.
No diet or feed change alone. Sharer doesn't change feeding independently.
Movement adjustment in coordination. More or less riding only in agreement.
