Comparing Amino-Acid Profiles? 7 Boxes Höveler Pur.Muskel Ticks for the Label-Reader
Quick answer: Höveler Pur.Muskel is a supplementary muesli formulated to support muscle development, with lysine at 0.85%, threonine at 0.6%, and methionine+cysteine at 0.5% on top of 20% raw protein. It is competition safe, alfalfa-free, and folded into a complete ration. At $52.99 for a 44 lb bag, it rewards label-readers who start with the amino-acid line. Last checked: September 2026.
Label-readers understand the frustration: most feeds lead with crude protein and go quiet on amino acids. Here are the seven boxes Pur.Muskel ticks when the amino-acid line is the first thing you look for on a bag.
1. The amino-acid box: the limiting amino acids, stated in print
Pur.Muskel states lysine at 0.85%, threonine at 0.6%, and methionine+cysteine at 0.5%, with methionine alone at 0.25%. Lysine is the first-limiting amino acid for muscle development, so finding it in print at 0.85% is what turns a protein claim into a plan. The feed is formulated for muscle building and is part of a full ration.
The benefit: the muscle-development building blocks named and measured, so the ration can be planned around them.
2. The protein box: 20% raw protein with 160 g/kg digestible
Amino acids only matter if the protein behind them is real. Pur.Muskel carries 20% raw protein and 160 g of digestible crude protein per kg — what the horse absorbs, not just the label total. Together with the stated amino acids, that is a complete protein story.
Who this is for: buyers who want amount and quality on the same line of the label.
3. The starch box: 5.8% starch, 4.1% sugar
The energy driving work in Pur.Muskel is not coming from grain: 15.0% raw fat and 14.1 MJ/kg of digestible energy do the work while starch sits at 5.8% and sugar at 4.1%. That fits metabolically sensitive breeds and keeps the amino-acid program working without a starch surge.
The benefit: a protein-forward ration that skips the grain load.
4. The gut-support box: 18.7% crude fiber and gentle on the stomach
Pur.Muskel brings 18.7% crude fiber and is formulated to be easy on the stomach, and it is alfalfa-free. A high-protein plan only works if the horse takes it willingly day after day.
Who this is for: owners whose high-protein ambitions keep getting undone by a fussy gut.
5. The micronutrient box: no added vitamins or minerals
There are no added vitamins or minerals in Pur.Muskel, by intent, with magnesium at 0.8%. It slots into a custom feeding plan next to your balancer without repeating micronutrients — clean integration, as a supplementary feed should work.
The benefit: a targeted protein-and-amino component inside a plan you control.
6. The competition box: competition safe and FEI-compliant
Pur.Muskel is competition safe and FEI-compliant. Buyers in competitive barns can tick this box without a phone call: the amino-acid program you feed in training is legal at recognized competition, so there is no last-minute ration shuffle before a show.
Who this is for: riders whose season runs from the training barn to the show ring.
7. The value box: $52.99 for a 44 lb bag
Stated amino acids at a stated price: $52.99 gets you a 44 lb bag, and gram dosing stretches it far. A 1,000 lb horse in medium work gets 50–80 g daily, so the per-day cost of that 0.85% lysine is modest. The 44 lb bag listing is on bifid's product page.
The benefit: a named amino-acid program costed per working day, not by the sack.
How to feed it
This is a supplementary feed: always mixed into a complete ration with forage alongside, never fed as the whole diet. Rates per 220 lb (100 kg) body weight per day:

The ranges are tight in gram terms, so weigh rather than scoop. The bifid feeding calculator returns your horse's exact daily rate.

Frequently asked questions
Why does lysine matter so much in a muscle feed?
Lysine is the first-limiting amino acid for muscle development — if it falls short, the rest of the protein goes to waste. Pur.Muskel states it at 0.85% so you can see the level rather than assume.
Are methionine and cysteine counted separately?
The label gives methionine at 0.25% and the combined methionine+cysteine figure at 0.5%, together with threonine at 0.6%. Those are the sulfur amino acids and the second major limiting pair for topline work.
Does it contain soy?
Yes. Soy flakes are one https://horse-feed-nutrition588.scriblorax.com/posts/5-reasons-eventers-reach-for-hoveler-pur.muskel of the core ingredients, which is part of how the amino-acid profile is built. It is alfalfa-free, rather than soy-free.
Is this feed complete on its own?
No. Pur.Muskel is a supplementary feed added to a complete ration. It contains no added vitamins or minerals, so your balancer and forage fill the gap.
