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 feel 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 steady fuel that lasts. Pur.Muskel was built around the steady kind. Seven ways it supports staying power.

1. Fat-fueled energy: 15.0% raw fat

Pur.Muskel lists 15.0% raw fat, drawn from linseed oil, flaxseed, and sunflower seed. Fat provides energy that releases slowly — the kind a horse still carries 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 carries 14.1 MJ/kg of digestible energy and 11.9 MJ/kg metabolizable energy. Stamina work depends on measured energy, and this is where the figures come 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 stays even. 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 demands muscle that goes the distance. Pur.Muskel provides 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine, backing muscle development across repeated long sessions. Its stated Functionality is Muscle Building.

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

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

A real owner 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 trust 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 to a different plan.

The benefit: the ration tracks the workload rather than guessing at it.

7. Competition safe and FEI-compliant

Trail 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 stands behind 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 measured, not assumed.

How to feed it

Pur.Muskel is a supplementary feed mixed into a complete ration — never a standalone complete feed. Rates per 220 lb (100 kg) of body weight per day:
