The first forty minutes feel great; the last https://horse-feed-nutrition276.inkharbory.com/posts/9-reasons-hoveler-pur.muskel-supports-a-senior-horse-still-in-work twenty fall apart. When a horse fades late in work, the ration is usually supplying quick fuel that burns out 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 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 carries 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 figures 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 stays even. Starchy feeds can give a burst followed by a dip — the opposite of what a long work session needs.
Who this is for: horses whose energy spikes and dips 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, supporting 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 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 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 to a different plan.
The benefit: the ration tracks the workload instead of guessing at it.
7. Competition safe and FEI-compliant
Trail days, hunter paces, long clinics — the ration remains legal and unchanged. 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 scored, not assumed.
How to feed it
