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 is added to a complete ration, never fed alone. $52.99 for a 44 lb bag. Last checked: September 2026.
Loose droppings after meals, a sore-belly attitude under saddle, manure in the water bucket — grain sensitivity announces itself in ways no owner misses. The usual advice is simple: take the grain out. The trickier part is replacing the energy and protein it was supplying. Pur.Muskel was formulated for that swap. Seven ways it helps.
1. Starch at just 5.8%
Grain-sensitive muscle building feed for horses horses react to the starch load, and Pur.Muskel holds it at 5.8% — only a horse feed to increase muscle mass fraction of what a typical grain concentrate carries.
Who this is for: horses that go sour or loosen when grain increases.
2. Sugar held at 4.1%
Sugar travels with starch in most quick-carbohydrate complaints, so Pur.Muskel holds that figure at 4.1% too. The feed fits metabolically sensitive breeds on purpose.
The benefit: a concentrate you can include 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 bypasses the starch route that bothers sensitive horses.
Who this is for: horses that still need 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 among its ingredients. Fiber is the grain-sensitive horse's natural territory — the gut processes it with ease.
The benefit: energy delivered the way the horse's gut likes it.
5. 20% raw protein in a small daily dose
The mix supplies 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, easy portions suit a sensitive digestive system. (The feed contains soy flakes and is not soy-free; it is alfalfa-free.)
Who this is for: muscle-building programs running on a reduced-starch ration.
6. Gentle on the stomach — stated, not implied
The fact sheet calls Pur.Muskel gentle on the stomach and notes its suitability for metabolically sensitive breeds. With no added vitamins or minerals, it slots into a custom feeding plan without repeating a single input.
Who this is for: owners managing a fully balanced, carefully 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 supports 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 goes.
How to feed it
Pur.Muskel is a supplementary feed added to a complete ration — never a standalone complete feed. Rates per 220 lb (100 kg) of 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)Example: a 1,000 lb horse in medium work gets 50–80 g per day. Introduce any new feed gradually, tune to condition and training intensity, and keep forage always alongside. Persistent digestive upset warrants a veterinary check.
