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 fade late in work — 14.1 MJ/kg of digestible energy from 15.0% raw fat, plus 20% raw protein to hold 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 fades late in work, the ration is usually delivering quick fuel that burns out instead of slow fuel that holds. Pur.Muskel was built around the steady kind. Seven ways it supports staying power.
1. Fat-fueled energy: 15.0% raw fat
Pur.Muskel carries 15.0% raw fat, drawn from linseed oil, flaxseed, and sunflower seed. Fat delivers slow-release energy — the kind a horse still has 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. Stamina work runs on measured energy, and this is where the numbers come from.
The benefit: fuel calculated for the whole ride, not just the warm-up.
3. Low starch keeps the energy steady
At 5.8% starch and 4.1% sugar, the energy profile stays even. Starch-heavy feeds can give a spike followed by a slump — the reverse of what a long work session calls for.
Who this is for: horses whose energy spikes and dips 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, supporting 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 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 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. Long-ride weeks and easy weeks can be fed differently.
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 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 taken on faith.
