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 added to 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 shout about 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 https://sites.google.com/view/horse-muscle-supplement/ 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 program. The feed is formulated for muscle building and is added to a full ration.

The benefit: the muscle-development building blocks spelled out and measured, so the ration can be built 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 full 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 grain: 15.0% raw fat and 14.1 MJ/kg of digestible energy carry while starch sits at 5.8% and sugar at 4.1%. That suits 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 eats it comfortably 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 design, with magnesium at 0.8%. It slots into a custom feeding plan alongside your balancer without repeating micronutrients — clean integration, as a supplementary feed is meant to 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 buys a 44 lb bag, and gram dosing makes it go 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 priced by the 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:

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)

A 1,000 lb horse in medium work gets 50–80 g daily. The ranges are tight in gram terms, so measure rather than scoop. The bifid feeding calculator returns your horse's exact daily rate.

Key specs at a glance: lysine 0.85%, threonine 0.6%, methionine+cysteine 0.5%, 20% raw protein, 160 g/kg digestible crude protein, 5.8% starch, 44 lb bag, $52.99.

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 runs short, the rest of the protein goes to waste. Pur.Muskel states it at 0.85% so you can see the level rather than guess.

Are methionine and cysteine counted separately?

The label gives methionine at 0.25% and the combined methionine+cysteine figure at 0.5%, alongside 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 of the core ingredients, which is part of how the amino-acid profile is built. It is alfalfa-free, not 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 complete the picture.
