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 fall apart. When a horse fades late in work, the ration is usually delivering 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 in.
Who this is for: horses that come out firing and end up 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 depends on energy you can measure, and this is where the numbers are drawn from.
The benefit: fuel planned 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. Starch-heavy feeds can give a spike followed by a slump — the opposite of what a long session needs.
Who this is for: horses whose energy spikes and dips mid-work.
4. 20% raw protein to protect working muscle
Stamina needs muscle that lasts the distance. Pur.Muskel provides 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine, supporting muscle development through 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 believe other owners before they trust a spec sheet.
6. Small doses, easy to scale to the training week
As a supplementary feed, Pur.Muskel is served 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
Trail days, hunter paces, long clinics — the ration stays legal and consistent. https://equine-nutrition986.lowescouponn.com/building-a-custom-ration-5-boxes-hoveler-pur-muskel-ticks-for-the-micronutrient-planner Pur.Muskel is competition safe and FEI-compliant, from Höveler, a German maker of horse feed since 1905.

Pur.Muskel is formulated to back staying power with 14.1 MJ/kg of digestible energy delivered mostly as 15.0% raw fat rather than starch. A verified review from March 14, 2019 is titled "Noticeable difference in stamina."
How does low starch help endurance?
At 5.8% starch and 4.1% sugar, the energy comes in slowly from fat and fiber rather than as a fast starchy spike — which is the profile steady work runs on.
How much should I feed for a heavy training week?
0.18–0.22 lb (80–100 g) per 220 lb (100 kg) of body weight daily in heavy work. The gram ranges are small, so changes are simple to make.
