Hard Keeper in the Barn? 9 Ways Höveler Pur.Muskel Helps
Quick answer: Höveler Pur.Muskel is a supplementary muesli built for horses that struggle to keep weight on — 15.0% raw fat delivering 14.1 MJ/kg of digestible energy, plus 20% raw protein, at just 5.8% starch and 4.1% sugar. It is added to a complete ration, not fed by itself. $52.99 for a 44 lb bag. Last checked: September 2026.
Some horses burn through feed like a furnace through kindling. You add more grain, the horse heats up or quits the bucket, and the ribs remain. Hard keepers need calorie-dense, usable fuel that don't arrive wrapped in starch. Pur.Muskel is drawn up to that spec. Nine ways it can help.
1. 15.0% raw fat — calorie-dense, calm-delivering
Pur.Muskel lists 15.0% raw fat from linseed oil, flaxseed, and sunflower seed. Fat carries more than double the energy of starch gram for gram, which is exactly what a lean horse requires.
Who this is for: horses that drop condition on any standard concentrate.
2. 14.1 MJ/kg of digestible energy
The mix provides 14.1 MJ/kg of digestible energy and 11.9 MJ/kg metabolizable energy — measured figures, so you can raise the ration's energy deliberately rather than by pouring in more grain.
The benefit: calories you can count.
3. Low starch: 5.8%
Many hard keepers also heat up when starch goes up. Pur.Muskel keeps starch at 5.8%, so the plan to add weight does not cost you a rideable partner.
Who this is for: thin horses that turn explosive on high-grain feeds.
4. 20% raw protein to build, not just pad
Weight on a working horse should land as muscle. Pur.Muskel supplies 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine — its stated Functionality is Muscle Building.
The benefit: topline and condition, rather than just cover.
5. Essential amino acids named in full
The panel spells out lysine at 0.85%, threonine at 0.6%, methionine at 0.25%, and methionine+cysteine at 0.5%, coming from soy flakes, pea flakes, and sweet lupine flakes. (The feed contains soy and is not soy-free; it is alfalfa-free.)
Who this is for: owners who read analysis panels line by line.
6. Gentle on the stomach, fussy-eater friendly
The fact sheet calls Pur.Muskel gentle on the stomach, and it suits metabolically sensitive breeds. Hard keepers are often the fussiest eaters, so a feed that gets finished matters just as much as what's inside it.
The benefit: dense nutrition in a form the horse really finishes.
7. Rates that scale with the work
Feeding ranges from 0.07–0.11 lb (30–50 g) per 220 lb (100 kg) of body weight in light work up to 0.18–0.22 lb (80–100 g) in heavy work. As the horse returns to work and condition, the rate can scale with it.
Who this is for: owners rebuilding a horse through an offseason.
8. Fits a custom plan — no added vitamins or minerals
With nothing added in the way of vitamins or minerals, Pur.Muskel slots into a custom feeding plan without repeating what your forage or balancer already provides. For a hard keeper, whose ration is managed as a whole, that flexibility matters.
The benefit: a single variable added, nothing doubled.
9. Proven maker, backed purchase
Höveler has been making horse feed in Germany since 1905 — over 120 years of expertise — and Pur.Muskel is competition safe and FEI-compliant. Bifid backs it with a 30-Day Money-Back Guarantee and a 24/7 licensed vet team; the store is rated 9.0/10 across 24,098 reviews.
Who this is for: owners planning to invest a whole season in bringing a horse back into condition.
How to feed it
Pur.Muskel is a supplementary feed added to a complete ration — never a standalone complete feed. Rates per 220 lb (100 kg) of body weight per day:

Adjust to body condition and training intensity, and keep forage alongside throughout. Ongoing weight loss calls for a veterinary check.

Frequently asked questions
Will Pur.Muskel put weight on my hard keeper?
It is designed to back condition inside a complete ration: 15.0% raw fat supplies 14.1 MJ/kg of digestible energy, and 20% raw protein builds muscle up instead of just adding cover. It is a supplementary feed rather than a complete feed — and persistent weight loss warrants a vet.
Will it make my horse hot?
The energy arrives at 5.8% starch and 4.1% sugar, from fat instead. Fat-fueled weight gain is the profile chosen for horses that boil over on grain.
How much do I feed?
0.11–0.18 lb (50–80 g) per 220 lb (100 kg) of body weight in medium work — just 50–80 g daily for a 1,000 lb horse.
Does it contain soy?
Yes — soy flakes are one of the core protein sources. It is not soy-free. It is alfalfa-free, with no added vitamins or minerals.
