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, not fed by itself. $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 fast fuel that burns off instead of slow fuel that holds. Pur.Muskel was built around the steady kind. Seven ways it backs 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 delivers slow-release energy — 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 carries 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 come 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 stays even. Starchy feeds can give a spike followed by a slump — the opposite 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 provides 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine, supporting muscle development across repeated long sessions. Its stated Functionality is Muscle Building.
The benefit: the engine stays together from start to finish.
5. Real-world staying power, reported by an owner
A verified review from Jessica, dated 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 trust 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 matches the workload rather than guessing at it.
7. Competition safe and FEI-compliant
Trail days, hunter paces, long clinics — the ration stays legal https://low-starch-horse-feed-zrqg932.sagecurrent.com/posts/switching-to-hoveler-pur.muskel-safely-9-steps-for-the-transition 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.
