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 muscle and topline on a soy-free ration. Price: $49.99. Last checked: September 2026.

Not all protein is equal, and increasingly, not all protein is welcome: soy sensitivity and soy-free preferences have gone mainstream in the barn. The question that matters is not just https://sites.google.com/view/high-energy-horse-feed/ "how much protein" but "from what source". Original Sport answers both, with declared figures and no soy in sight. Here are the five sources doing the work.

1. Alfalfa — the forage protein foundation

Alfalfa leads the ingredient list, and leafy alfalfa is among 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 packaged in the fiber a working horse's gut is built to process. The benefit: the biggest protein contribution arriving as forage, not powder.

2. Sunflower extraction meal — the soy-free workhorse

Sunflower extraction meal is a classic European protein ingredient, and it is just the kind of source that lets a premium formula go soy-free without giving up protein quality. It sits next to alfalfa in the ingredient list, adding to the ration's protein contribution at 15.1% crude protein. Who this is for: owners who have taken 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 whole-food-style protein and starch source that also adds texture variety. Along with their protein contribution, they make the feed more inviting to eat, which helps a horse in work actually finish its ration day after day. The benefit: protein visible in the bucket, from an ingredient with a clean 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 part of 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 protein from the ingredient base. That is why the feed can state 15.1% crude protein and a muscle-function, recovery-focused 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 sole 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 fully 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 really absorb and put to 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. We describe nutritional support; the training does the building.

Can I combine it with a protein supplement?

Look at the complete ration first. The 24/7 licensed vet team is happy to help you work out whether anything extra is needed on top of the declared protein and amino acids.

Is it competition-safe?

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