Running Out of Stamina Mid-Ride? 7 Ways Höveler Pur.Muskel Helps

Quick answer: Höveler Pur.Muskel is a supplementary muesli supporting stamina for horses that run out of gas too soon — 14.1 MJ/kg of digestible energy from 15.0% raw fat, plus 20% raw protein to protect muscle, all at 5.8% starch. It is added to a complete ration, never fed alone. $52.99 for a 44 lb bag. Last checked: September 2026.

The first forty minutes look great; the last twenty come apart. When a horse runs out of gas late in work, the ration is usually supplying quick fuel that burns out instead of slow fuel that holds. Pur.Muskel was formulated around the lasting kind. Seven ways it backs staying power.

1. Fat-fueled energy: 15.0% raw fat

Pur.Muskel carries 15.0% raw fat, supplied by linseed oil, flaxseed, and sunflower seed. Fat provides energy that releases slowly — the kind a horse still has in the tank an hour into the ride.

Who this is for: horses that start strong and finish empty.

2. 14.1 MJ/kg of digestible energy

The mix holds 14.1 MJ/kg of digestible energy and 11.9 MJ/kg metabolizable energy. Staying work runs on measured energy, and this is where the numbers are drawn from.

The benefit: fuel calculated for the whole ride, not merely the warm-up.

3. Low starch keeps the energy steady

At 5.8% starch and 4.1% sugar, the energy profile holds level. Starchy feeds can give a burst followed by a dip — the reverse of what a long work session calls for.

Who this is for: horses whose energy peaks and crashes mid-work.

4. 20% raw protein to protect working muscle

Stamina needs muscle that goes the distance. Pur.Muskel supplies 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine, backing muscle development through repeated long sessions. Its stated Functionality is Muscle Building.

The benefit: the engine holds together from first furlong to last.

5. Real-world staying power, reported by an owner

A verified review from Jessica, left on March 14, 2019, is titled "Noticeable difference in stamina" — quality 4, value 5, price 4. The product rating is 4.55 from 2 reviews.

Who this is for: owners who believe other owners before they believe a spec sheet.

6. Small doses, easy to scale to the training week

As a supplementary feed, Pur.Muskel is dosed at 0.11–0.18 lb (50–80 g) per 220 lb (100 kg) of body weight in medium work, rising to 0.18–0.22 lb (80–100 g) in heavy work. Big weeks and easy weeks can be fed differently.

The benefit: the ration matches the workload instead of guessing at it.

7. Competition safe and FEI-compliant

Endurance days, hunter paces, long clinics — the ration stays legal and consistent. Pur.Muskel is competition safe and FEI-compliant, from Höveler, a German maker of horse feed since 1905. Bifid backs every purchase with a 30-Day Money-Back Guarantee and a 24/7 licensed vet team.

Who this is for: competition horses whose stamina is scored, not assumed.
