9 Muscle Development Reasons Höveler Pur.Muskel Earns Its Place in the Ration
Quick answer: Höveler Pur.Muskel is a supplementary muesli for muscle development, carrying 20% raw protein with 160 g/kg digestible crude protein and the key amino acids lysine 0.85% and threonine 0.6%. It is added to a complete ration, is FEI-compliant, and costs $52.99 for a 44 lb bag — a strong pick for horses in training that need protein above what their base ration provides. Last checked: September 2026.
Every owner building a horse's condition knows the frustration: weeks of correct work, and the topline still looks unchanged. Muscle is built from protein quality, not just the amount — and that is exactly where Pur.Muskel is formulated to contribute. Here are nine reasons it is the feed for the job, added to a full ration.
1. 20% raw protein is the headline number
Muscle is protein, and Pur.Muskel brings 20% raw protein to the ration. That is a serious protein contribution from a muesli format, which is why the product's stated Functionality is Muscle Building.
Who this is for: horses in work that need protein above what their base ration delivers.
2. Digestible crude protein of 160 g/kg, not just crude numbers
A protein percentage only matters if the horse can use it. Pur.Muskel delivers 160 g/kg digestible crude protein, so more of that 20% reaches the muscle-building machinery.
The benefit: fewer wasted protein dollars in each scoop.
3. Lysine at 0.85% — the first-limiting amino acid
Lysine is the amino acid most often short in horse rations. Pur.Muskel supplies 0.85% lysine, working to maintain the amino acid balance a horse needs to support muscle development.
Who this is for: owners whose base feed does not state a lysine figure.
4. Methionine and threonine complete the picture
Beyond lysine, Pur.Muskel lists 0.25% methionine and 0.6% threonine, with methionine+cysteine at 0.5%. These essential amino acids support muscle protein and coat quality together.
The benefit: a complete amino acid profile in one supplementary feed.
5. Built from real protein sources: soy flakes, pea flakes, sweet lupine
The ingredient list speaks for itself: soy flakes, sweet lupine flakes, and pea flakes are the protein carriers, alongside meadow lyegrass and flaxseed. Soy flakes are included deliberately — this feed contains soy and is not marketed as soy-free.
Who this is for: owners who read ingredient lists before price tags.
6. Energy to fuel the work, not just the protein
Muscle needs a training stimulus and fuel. Pur.Muskel adds 11.9 MJ/kg metabolizable energy with 15.0% raw fat, so the horse has energy to put in proper work while the protein backs development.
The benefit: protein and energy arriving together, in the right ratio.
7. Gentle on the stomach at 5.8% starch
Muscle-building plans fail when horses go sour or hot. Pur.Muskel holds starch at 5.8% and sugar at 4.1%, and is described as easy on the stomach — so the plan stays consistent.
Who this is for: metabolically sensitive breeds that still need to build muscle.
8. No added vitamins or minerals, so your plan stays custom
Pur.Muskel is alfalfa-free and contains no added vitamins or minerals. That means you can add targeted protein and energy without doubling your micronutrient package — the main point of a supplementary feed in a custom plan.
Who this is for: owners running a balancer or a vet-designed micronutrient program.
9. Owner-reported results, competition safe, and risk-free to try
The product rates 4.55 from 2 reviews, and Jessica's May 21, 2024 review notes the horses maintain stronger muscle condition. It is competition safe and FEI-compliant, made in Germany by a firm with over 120 years of experience, and backed by bifid's 30-Day Money-Back Guarantee.
Who this is for: anyone who wants proof before committing to a 44 lb bag.

Frequently asked questions
What protein level does Pur.Muskel have?
20% raw protein, with 160 g/kg digestible crude protein. It also supplies lysine at 0.85%, threonine at 0.6%, and methionine at 0.25%.

No. It is a supplementary feed, added to a complete ration with forage. Its role is to bring muscle-building protein and energy into a complete nutrition plan.
Can a metabolically sensitive horse use it?
Yes. Starch is 5.8% and sugar 4.1%, and the summary specifically names metabolically sensitive breeds. It is also easy on the stomach.
Does it contain soy?
Yes — soy flakes are a central protein source. Pur.Muskel is not soy-free, so avoid it if your horse has a soy sensitivity.
How soon will I see a difference?
No supplement takes the place of correct training, but Jessica's May 2024 review notes horses maintain stronger muscle condition. The product rates 4.55 from 2 reviews, and bifid's 30-Day Money-Back Guarantee lets you assess it over a full trial.
