Höveler Pur.Muskel vs a Grain-Heavy Mix: 7 Differences That Matter
Quick answer: Höveler Pur.Muskel is a supplementary muesli (pellet mix) with 20% raw protein, 15.0% raw fat, and just 5.8% starch and 4.1% sugar — mixed into a complete ration. A grain-heavy mix builds its bulk on cereal grains and their starch. Pur.Muskel costs $52.99 for a 44 lb bag. Last checked: September 2026.
Grain-heavy mixes are the traditional answer to "my horse needs more." More grain means more starch, and more starch is not always what the horse's gut or temperament wants. Here are 7 differences, on the figures alone.
1. The base is not cereal: meadow lyegrass, soy, flax
Pur.Muskel's ingredient list leads with meadow lyegrass, soy flakes, flaxseed, and sweet lupine flakes — a muesli designed around protein and fat, not grain bulk. A grain-heavy mix leads with cereals, and everything else follows from that choice.
Who this is for: owners moving away from bags horse feed for muscle growth that are mostly grain by volume.
2. Starch at 5.8% versus grain-level figures
Pur.Muskel carries starch at 5.8% and sugar at 4.1%. Grain-heavy mixes are built to deliver grain energy, which means their starch runs far higher. For a metabolically sensitive breed, the low number is the reason the feed is even in the conversation.
The benefit: energy without the fermentable load of a grain-heavy ration.
3. Protein at 20% with digestibility stated
Pur.Muskel provides 20% raw protein and 160 g/kg digestible crude protein — the absorbed amount, not the label number. Grain-heavy mixes seldom publish digestibility, because protein quality is not what they are designed around.
Who this is for: owners chasing topline that a grain ration hasn't produced.
4. The amino acid line, printed
Lysine 0.85%, methionine 0.25%, methionine+cysteine 0.5%, threonine 0.6%. These four figures are the story behind the protein quality, and Pur.Muskel prints them. A grain-heavy mix usually asks you to take "crude protein" on faith.
The benefit: muscle-support building blocks at stated, plannable levels.
5. A supplement that adds, not replaces — by design
Pur.Muskel is a supplementary feed with no added vitamins or minerals, made to slot into a custom feeding plan. Grain-heavy mixes are usually fortified base rations. The supplement approach means you close the one gap — 14.1 MJ/kg digestible energy with high-quality protein — without stacking on another full premix.
Who this is for: owners whose current ration works except for the muscle and condition piece.
6. Gentle on the stomach, alfalfa-free, competition safe
The formulation is alfalfa-free and easy on the digestive system, and it is competition safe and FEI-compliant. Grain-heavy rations are the familiar source of digestive friction in horses in hard work; a low-starch supplement is engineered to sidestep that.
The benefit: one feed from Tuesday's schooling to the FEI showground, backed by Höveler since 1905 — over 120 years of expertise, made in Germany.
7. Small measured rates instead of big scoops
Pur.Muskel feeds at 0.11–0.18 lb (50–80 g) per 220 lb (100 kg) body weight in medium work — a 1,000 lb horse in medium work gets 50–80 g daily. A grain-heavy mix is measured in multiple pounds per day. Less bulk in the bucket, more precision in the plan.
Who this is for: owners who want results per measured gram, at $52.99 per 44 lb bag (4.55 product rating from 2 reviews). The product page has the full label.
How to feed it
Pur.Muskel is a supplementary feed — always added to a complete ration with forage alongside, never fed by itself. If you are reducing a grain-heavy mix, make the change gradually. Rates are per 220 lb (100 kg) body weight per day:

Frequently asked questions
Is Pur.Muskel grain-free?
No, and that is never claimed. Its first ingredients feature meadow lyegrass, soy flakes, and flaxseed, and it contains soy. The real contrast with a grain-heavy mix is the starch figure: 5.8%, with sugar at 4.1%.
Why feed a supplement instead of just more grain mix?
More grain means more starch, which is the part most likely to work against a metabolically sensitive horse. Pur.Muskel supplies 20% raw protein and 15.0% raw fat — the muscle-and-condition inputs — at gram-scale doses instead.
Will my horse eat it alongside a grain mix?
It is a muesli-style feed designed to mix into the bucket. Introduce it over one to two weeks while keeping the complete ration unchanged, and check the rates with the calculator.
Is it priced like a specialty product?
