Höveler Pur.Muskel vs a High-Starch Feed: 9 Differences That Matter
Quick answer: Höveler Pur.Muskel is a supplementary muesli with starch held at 5.8% and sugar at 4.1% while still delivering 14.1 MJ/kg digestible energy — added to a complete ration. A high-starch feed draws its energy from cereal and pays for it in glycemic spikes. Pur.Muskel is $52.99 for a 44 lb bag. Last checked: September 2026.
If your horse gets fizzy, touchy, or worse on a grain-heavy ration, starch is usually the first number to check. Here are 9 differences between a purposefully low-starch supplement and a starch-heavy feed — compared only on published figures.
1. 5.8% starch, stated plainly
Pur.Muskel publishes starch at 5.8%. High-starch feeds are built on cereal grains, and their starch figures run many times higher by design. For metabolically sensitive breeds, that single number decides whether the feed fits at all.
Who this is for: owners shopping for a feed their vet would nod at for a metabolically sensitive horse.
2. Sugar at 4.1% to match
The low-starch profile is paired with 4.1% sugar. High-starch feeds commonly carry molasses to bind the mix, which stacks sugar on top of grain. Pur.Muskel's ingredient list leads with meadow lyegrass, soy flakes, and flaxseed — not a sugar coating.
The benefit: an energy profile that does not ride the sugar-starch roller coaster.
3. The energy still arrives: 14.1 MJ/kg
Low starch does not mean low energy. Pur.Muskel provides 14.1 MJ/kg digestible energy and 11.9 MJ/kg metabolizable energy, carried substantially by 15.0% raw fat. A high-starch feed also delivers energy, but from the fraction of the diet most likely to cause behavior and metabolic friction.
Who this is for: horses in serious work that need complete energy without the fizz.
4. Muscle support, not just fuel
Pur.Muskel brings 20% raw protein and 160 g/kg digestible crude protein, with lysine at 0.85% and threonine at 0.6%. High-starch feeds are fuel-first formulations; muscle work is not their design goal. This one is listed for that job.
The benefit: muscle-support protein and energy in the same measured serving.
5. Built for a custom plan, with no added vitamins or minerals
Pur.Muskel is a supplementary feed that adds no vitamins or minerals, so it fits into a custom feeding plan without upsetting your balancer's math. A high-starch feed is usually fortified as a base ration — its micronutrient decisions are chosen for you.
Who this is for: https://sites.google.com/view/muscle-building-feed-for-horse/ owners running a vet-reviewed, deliberate nutrition plan.
6. Gentle on the stomach and alfalfa-free
The formulation is alfalfa-free and gentle on the stomach. Grain-heavy rations put more fermentable load on the hindgut; a low-starch feed is built to avoid asking the gut to carry that load.
The benefit: a ration your horse's digestion has fewer complaints about, at doses of just 30–100 g per 220 lb (100 kg).
7. Competition safe and FEI-compliant
Pur.Muskel is competition safe and FEI-compliant, made by Höveler in Germany since 1905 — over 120 years of expertise. That covers both training days and show days from one formulation, with no label archaeology required.
Who this is for: competitive riders who need the ration approved for FEI competition.
8. Dosed in grams, not gallons of grain
Light work calls for 0.07–0.11 lb (30–50 g) per 220 lb (100 kg) body weight daily; heavy work tops out at 0.18–0.22 lb (80–100 g). Swapping out high-starch energy means taking grain out of the bucket, not putting more in — the concentrated dosing makes that swap easy to manage.
The benefit: a smaller grain bill in the bucket, weighed in grams rather than scooped by volume.
9. Known price, known rating, real backup
Pur.Muskel costs $52.99 for a 44 lb bag and holds a 4.55 rating from 2 reviews — one owner noting a clear difference in stamina. bifid adds a 30-Day Money-Back Guarantee and a 24/7 licensed vet team for the questions that come up during the switch. The product page lists the full label.
Who this is for: owners ready to step away from a high-starch ration with something to fall back on.
How to feed it
Pur.Muskel is a supplementary feed — always added to a complete ration with forage in the bucket, never fed alone. When reducing a high-starch feed, transition gradually over one to two weeks. Rates are per 220 lb (100 kg) body weight per day:

Frequently asked questions
Is 5.8% starch genuinely low?
It is a low figure for a working-horse feed, and it is joined by 4.1% sugar. The formulation was designed with metabolically sensitive breeds in mind, which is why both numbers are on the label rather than omitted.
Where does the energy come from if not starch?
Largely from fat — Pur.Muskel carries 15.0% raw fat, with flaxseed and linseed oil — while still delivering 14.1 MJ/kg of digestible energy per kilogram.
Can I just swap the high-starch feed out for Pur.Muskel?
Not one-for-one. Pur.Muskel is a supplementary feed fed within a complete ration, not a complete feed on its own. Cut the high-starch portion back slowly, keep forage and balancer in place, and work out the supplement rate for your horse's size and workload.
Will a low-starch feed change my horse's attitude?
Feed changes can shift energy character, and many owners go low-starch for exactly that reason. Pur.Muskel is designed for metabolically sensitive breeds and supports steady condition and work.
