Hard Keeper in the Barn? 9 Ways Höveler Pur.Muskel Helps
Presented by @grainfree-completewauq669
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 go through feed like a furnace through kindling. You raise the grain, the horse heats up or quits the bucket, and the ribs stay. 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 exactly what a thin horse requires.
Who this is for: horses that lose weight on any 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 — 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 run hot when starch goes up. Pur.Muskel keeps starch at 5.8%, so the weight gain plan does not cost you a rideable horse.
Who this is for: thin horses that turn explosive 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, not just cover.
5. Essential amino acids named in full
The panel spells out lysine at 0.85%, threonine at https://hoveler-performance-horse-feed-zleo075.clarionvale.com/posts/hoveler-pur.muskel-9-reasons-grape-seed-flour-earns-its-place-in-this-muscle-muesli 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 gentle on the stomach, and it fits metabolically sensitive breeds. Hard keepers are often the pickiest eaters, so a feed that gets finished matters as much as what is in 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 work and condition, 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 provides. For a hard keeper, whose whole ration is usually being managed, that flexibility matters.
The benefit: a single 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 planning to invest a whole season in bringing a horse back.
How to feed it
Pur.Muskel is a supplementary feed mixed into a complete ration — never a standalone complete feed. Rates per 220 lb (100 kg) of body weight per day:
Work levelDaily rate per 220 lb (100 kg) body weight Light work0.07–0.11 lb (30–50 g) Medium work0.11–0.18 lb (50–80 g) Heavy work0.18–0.22 lb (80–100 g)Example: a 1,000 lb horse in medium work gets 50–80 g per day. Tune 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 full ration: 15.0% raw fat supplies 14.1 MJ/kg of digestible energy, and 20% raw protein builds muscle instead of just adding cover. It is a supplementary feed, not a complete feed — and persistent weight loss should be checked by a vet.
Will it make my horse hot?
The energy comes at 5.8% starch and 4.1% sugar, from fat rather than starch. 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 one of the core protein sources. It is not soy-free. It is alfalfa-free, with no vitamins or minerals added.
