Where the Protein Comes From in Höveler Original Sport: 5 Sources Behind 15.1%

Quick answer: Höveler Original Sport delivers 15.1% crude protein and 122 g digestible crude protein per kg DM from alfalfa, sunflower extraction meal, pea flakes, and linseed cake — soy-free, with added amino acids (lysine 1.0%, threonine 1.0%). Best for owners building topline and muscle on a soy-free ration. Price: $49.99. Last checked: September 2026.

Not all protein is created equal, and increasingly, not all protein is wanted: soy sensitivity and soy-free preferences have become mainstream in the barn. The question that matters is https://ameblo.jp/horse-feed-brands694/entry-12979879858.html not just "how much protein" but "from where". Original Sport answers both questions, with declared numbers and no soy in sight. Here are the five sources doing the work.

1. Alfalfa — the forage protein foundation

Alfalfa sits first on the ingredient list, and leafy alfalfa is one of the most dependable plant protein sources in horse feeding. In Original Sport it anchors a formula that tests at 15.1% crude protein and 122 g of digestible crude protein per kg of dry matter. Protein from forage comes wrapped in the fiber a working horse's gut is built to process. The benefit: the largest protein contribution arriving as forage, not powder.

2. Sunflower extraction meal — the soy-free workhorse

Sunflower extraction meal is a traditional European protein ingredient, and it is just the kind of source that lets a premium formula go soy-free without losing protein quality. It sits alongside alfalfa in the ingredient list, adding to the ration's protein contribution at 15.1% crude protein. Who this is for: owners who have removed soy out of the ration and need it properly replaced, not as a token.

3. Pea flakes — recognizable protein in a visible form

Pea flakes are right there in the muesli, visible in the bucket — a recognizable protein and starch source that also brings texture variety. Along with their protein contribution, they make the feed more inviting to eat, which helps a horse in work keep finishing its ration day after day. The benefit: protein you can see, from an ingredient with a good reputation.

4. Linseed cake — protein and fat in one ingredient

Linseed cake, the seed after oil extraction, contributes protein alongside its share of the formula's 9.0% crude fat. That dual role is elegant formulation: one ingredient supporting both the 15.1% crude protein figure and the energy density behind regular work. Who this is for: anyone who appreciates a formula where ingredients pull double weight.

5. Added amino acids make the protein count

Raw protein percentage is only half the story — the essential amino acids determine how usable it is. Original Sport adds lysine at 1.0%, threonine at 1.0%, and methionine plus cysteine at 0.93%, on top of the ingredient-base protein. That is why the feed can state 15.1% crude protein alongside a recovery-focused, muscle-function formulation with a straight face. The benefit: declared quality markers on top of a declared quantity — the complete protein picture.

Frequently asked questions

Is 15.1% crude protein too much for my horse?

For a horse in regular work, that level helps maintain muscle — it is a performance feed by design. It is not intended as the only ration for idle horses or growing stock; feed to the rate for the work level your horse is in.

Is the feed fully soy-free?

Yes — Original Sport is explicitly soy-free. Its protein comes from alfalfa, sunflower extraction meal, pea flakes, and linseed cake — the full panel is on the product page — with added lysine, threonine, and methionine plus cysteine.

What does "122 g digestible crude protein" mean?

It is the digestible crude protein per kg of dry matter — the part of the 15.1% the horse can actually absorb and use. It is a stricter, more honest number than crude protein alone.

Will this protein help build topline?

It supplies the building blocks — including lysine at 1.0% and threonine at 1.0% — to help muscle function alongside correct work and feeding at 0.88 lb (400 g) per 220 lb (100 kg) at medium work. This is nutritional support; the training does the building.

Can I combine it with a protein supplement?

Assess the complete ration first. The 24/7 licensed vet team is glad to help you figure out whether anything should be added to the declared protein and amino acids.

Is it competition-safe?

Yes — competition-safe and FEI-compliant. Verify specific rules with your event organizer.
