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, never fed alone. $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 heats up or drops the bucket, and the ribs stay. Hard keepers need dense, usable calories that don't arrive wrapped in starch. Pur.Muskel is built to that brief. Nine ways it can help.
1. 15.0% raw fat — calorie-dense, calm-delivering
Pur.Muskel carries 15.0% raw fat from linseed oil, flaxseed, and sunflower seed. Fat holds more than double the energy of starch gram for gram, which is just what a lean horse needs.
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 — figures you can measure, so you can add energy to the ration on purpose rather than by pouring in more grain.
The benefit: calories you can count.
3. Low starch: 5.8%
Plenty of hard keepers also run hot when starch rises. Pur.Muskel keeps starch at 5.8%, so the weight gain plan does not 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, rather than just cover.
5. Essential amino acids named in full
The panel spells out lysine https://soy-free-horse-feed-jimh342.meridiannest.com/posts/7-reasons-barrel-racers-feed-hoveler-pur.muskel 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 frequently the pickiest 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 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 condition and training, the rate can grow with it.
Who this is for: owners rebuilding a horse through an offseason.
8. Fits a custom plan — no added vitamins or minerals
With no added vitamins or minerals, Pur.Muskel integrates into a custom feeding plan without duplicating what your forage or balancer already supplies. For a hard keeper, whose whole ration is usually being managed, that flexibility counts.
The benefit: a single 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 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 planning to invest a season in bringing a horse back into condition.
How to feed it

Frequently asked questions
Will Pur.Muskel put weight on my hard keeper?
It is formulated to back condition inside a full ration: 15.0% raw fat supplies 14.1 MJ/kg of digestible energy, and 20% raw protein builds muscle rather than 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 rather than starch. Fat-fueled weight gain is the profile picked 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 daily 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 added vitamins or minerals.
