Worried About Grain Sensitivity? 7 Ways Höveler Pur.Muskel Helps
Quick answer: Höveler Pur.Muskel is a supplementary muesli formulated for grain-sensitive horses — 5.8% starch, 4.1% sugar, and 18.7% crude fiber, with energy from 15.0% raw fat rather than grain. It muscle building supplement for horses is added to a complete ration, not fed by itself. $52.99 for a 44 lb bag. Last checked: September 2026.
Loose droppings after meals, a sore gut attitude under saddle, manure in the water bucket — grain sensitivity makes itself known in ways no owner misses. The usual advice is straightforward: take the grain out. The trickier part is replacing the energy and protein it was supplying. Pur.Muskel was built for that exchange. Seven ways it can help.
1. Starch at just 5.8%
Grain-sensitive horses react to starch load, and Pur.Muskel holds it at 5.8% — a fraction of what a typical grain concentrate contains.
Who this is for: horses that go sour or get loose when grain goes up.
2. Sugar held at 4.1%
Sugar travels with starch in most quick-carbohydrate problems, so Pur.Muskel keeps that figure at 4.1% as well. The feed fits metabolically sensitive breeds by design.
The benefit: a concentrate you can add without the gut paying for it.
3. Energy from fat, not grain: 15.0% raw fat
The mix provides 15.0% raw fat from linseed oil, flaxseed, and sunflower seed, carrying 14.1 MJ/kg of digestible energy. Fat sidesteps the starch pathway that bothers horses with sensitive guts.
Who this is for: horses that still require full workday energy on a low-grain ration.
4. Fiber-forward at 18.7% crude fiber
Pur.Muskel carries 18.7% crude fiber, with meadow lyegrass in the mix. Fiber is the grain-sensitive horse's natural territory — the gut handles it happily.
The benefit: energy delivered the way the horse's gut likes it.
5. 20% raw protein in a small daily dose
The mix carries 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine, added at 0.07–0.11 lb (30–50 g) per 220 lb (100 kg) of body weight in light work. Small, gentle portions agree with a digestive system that startles easily. (The feed contains soy flakes and is not soy-free; it is alfalfa-free.)
Who this is for: muscle programs running on a reduced-starch ration.
6. Gentle on the stomach — stated, not implied
The fact sheet names Pur.Muskel gentle on the stomach and points out its suitability for metabolically sensitive breeds. With nothing extra added in the way of vitamins or minerals, it joins a custom feeding plan without doubling any input.
Who this is for: owners running a carefully balanced, fully controlled ration.
7. Competition safe and FEI-compliant
The delicate horse still has work to do. Pur.Muskel is competition safe and FEI-compliant, made by Höveler — German horse feed since 1905, over 120 years of expertise. Bifid backs the program with a 24/7 licensed vet team and a 30-Day Money-Back Guarantee.
Who this is for: competition horses whose gut decides how show day turns out.
How to feed it
