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 raise the grain, the horse gets hot or drops the bucket, and the ribs stay. Hard keepers need calorie-dense, usable fuel that don't arrive 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 twice the energy of starch per gram, which is just what a thin horse needs.
Who this is for: horses that lose weight on every standard concentrate.
2. 14.1 MJ/kg of digestible energy
The mix supplies 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 plan around.
3. Low starch: 5.8%
Plenty of hard keepers also heat up when starch rises. Pur.Muskel holds starch at 5.8%, so the weight gain plan won't cost you a rideable horse.
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 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 lists 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 names Pur.Muskel easy 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 actually eats.
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 comes back into condition and training, the rate can grow with it.
Who this is for: owners rebuilding a horse over an offseason.
8. Fits a custom plan — no added vitamins or minerals
With no added vitamins or minerals, Pur.Muskel slots into a custom feeding plan without repeating what your forage or balancer already supplies. For a hard keeper, whose ration is managed as a whole, that flexibility matters.
The benefit: one variable added, nothing doubled.
9. Proven maker, backed purchase
Höveler has made horse feed in Germany since 1905 — over 120 years of expertise — and Pur.Muskel is competition safe and FEI-compliant. Bifid pairs 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. Weight loss that continues calls for a veterinary check.
