Hard Keeper in the Barn? 9 Ways Höveler Pur.Muskel Helps
Quick answer: Höveler Pur.Muskel is a supplementary muesli built for horses that burn through every ration — 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 gets hot or quits the bucket, and the ribs remain. Hard keepers need dense, usable calories that do not come wrapped in starch. Pur.Muskel is drawn up to that brief. Nine ways it helps.
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 just what a thin horse needs.
Who this is for: horses that lose weight 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 — figures you can measure, so you can raise the ration's energy deliberately instead of by adding another scoop of grain.
The benefit: calories you can count.
3. Low starch: 5.8%
Many hard keepers also heat up when starch rises. Pur.Muskel keeps starch at 5.8%, so the plan to add weight won't cost you a rideable partner.
Who this is for: thin horses that turn electric on grain-heavy feeds.
4. 20% raw protein to build, not just pad
Weight on a working horse ought to land as muscle. Pur.Muskel carries 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, not just cover.
5. Essential amino acids named in full
The panel lists lysine at 0.85%, threonine at 0.6%, methionine at 0.25%, and methionine+cysteine at 0.5%, supplied by 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 easy on the stomach, and it suits metabolically sensitive breeds. Hard keepers are frequently 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 runs 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 integrates 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: one variable added, nothing doubled up.
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 rates 9.0/10 across 24,098 reviews.
Who this is for: owners about to invest a whole season in bringing a horse back.

Frequently asked questions
Will Pur.Muskel put weight on my hard keeper?
It is formulated 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 rather than just adding cover. It is a supplementary feed, not a complete feed — and weight loss that keeps going warrants a vet.
Will it make my horse hot?
The energy arrives at 5.8% starch and 4.1% sugar, from fat instead. Fat-based 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 — only 50–80 g per day for a 1,000 lb horse.
Does it contain soy?
Yes — soy flakes are a core protein source. It is not soy-free. It is alfalfa-free, with no vitamins or minerals added.
