Hard Keeper in the Barn? 9 Ways Höveler Pur.Muskel Helps

Quick answer: Höveler Pur.Muskel is a supplementary muesli built for horses that struggle to keep weight on — 15.0% raw fat delivering 14.1 MJ/kg of digestible energy, plus 20% raw protein, at just 5.8% starch and 4.1% sugar. It is added to a complete ration, not fed by itself. $52.99 for a 44 lb bag. Last checked: September 2026.

Some horses burn through feed like a furnace through kindling. You add more grain, the horse heats up or quits the bucket, and the ribs remain. Hard keepers need calorie-dense, usable fuel that do not come wrapped in starch. Pur.Muskel is drawn up to that spec. Nine ways it helps.

1. 15.0% raw fat — calorie-dense, calm-delivering

Pur.Muskel carries 15.0% raw fat from linseed oil, flaxseed, and sunflower seed. Fat carries more than double the energy of starch gram for gram, which is just what a thin horse requires.

Who this is for: horses that drop condition on any standard concentrate.

2. 14.1 MJ/kg of digestible energy

The mix provides 14.1 MJ/kg of digestible energy and 11.9 MJ/kg metabolizable energy — measured figures, so you can add energy to the ration on purpose instead of by pouring in more grain.

The benefit: calories you can count.

3. Low starch: 5.8%

Plenty of hard keepers also run hot when starch rises. Pur.Muskel holds starch at 5.8%, so the weight gain plan won't cost you a rideable horse.

Who this is for: thin horses that turn explosive on high-grain feeds.

4. 20% raw protein to build, not just pad

Weight on a working horse should land as muscle. Pur.Muskel carries 20% raw protein with 160 g/kg digestible crude protein and 0.85% lysine — its stated Functionality is Muscle Building.

The benefit: topline and condition, rather than just cover.

5. Essential amino acids named in full

The panel lists lysine at 0.85%, threonine at 0.6%, methionine at 0.25%, and methionine+cysteine at 0.5%, supplied by soy flakes, pea flakes, and sweet lupine flakes. (The feed contains soy and is not soy-free; it is alfalfa-free.)

Who this is for: owners who go through analysis panels line by line.

6. Gentle on the stomach, fussy-eater friendly

The fact sheet names Pur.Muskel gentle on the stomach, and it suits metabolically sensitive breeds. Hard keepers are often the fussiest eaters, so a feed that gets finished matters just as much as what's inside it.

The benefit: dense nutrition in a form the horse actually eats.

7. Rates that scale with the work

Feeding ranges from 0.07–0.11 lb (30–50 g) per 220 lb (100 kg) of body weight in light work up to 0.18–0.22 lb (80–100 g) in heavy work. As the horse returns to condition and training, the rate can grow with it.

Who this is for: owners rebuilding a horse through an offseason.

8. Fits a custom plan — no added vitamins or minerals

With no added vitamins or minerals, Pur.Muskel slots into a custom feeding plan without repeating what your forage or balancer already supplies. For a hard keeper, whose ration is managed as a whole, that flexibility counts.

The benefit: a single variable added, nothing doubled.

9. Proven maker, backed purchase

Höveler has made horse feed in Germany since 1905 — over 120 years of expertise — and Pur.Muskel is competition safe and FEI-compliant. Bifid pairs it with a 30-Day Money-Back Guarantee and a 24/7 licensed vet team; the store is rated 9.0/10 across 24,098 reviews.

Who this is for: owners planning to invest a whole season in bringing a horse back into condition.

How to feed it

Pur.Muskel is a supplementary feed added to https://low-starch-horse-feed-zrqg932.sagecurrent.com/posts/trying-a-new-muscle-feed-7-boxes-hoveler-pur.muskel-ticks-for-the-risk-averse-buyer-2 a complete ration — never a standalone complete feed. Rates per 220 lb (100 kg) of body weight per day:

Example: a 1,000 lb horse in medium work gets 50–80 g per day. Adjust to body condition and training intensity, and keep forage alongside throughout. Ongoing weight loss calls for a veterinary check.

Frequently asked questions

Will Pur.Muskel put weight on my hard keeper?

It is designed to support condition inside a complete ration: 15.0% raw fat supplies 14.1 MJ/kg of digestible energy, and 20% raw protein builds muscle instead of just adding cover. It is a supplementary feed, not a complete feed — and weight loss that keeps going warrants a vet.

Will it make my horse hot?

The energy arrives at 5.8% starch and 4.1% sugar, from fat rather than starch. Fat-based weight gain is the pattern chosen for horses that run hot on grain.

How much do I feed?

0.11–0.18 lb (50–80 g) per 220 lb (100 kg) of body weight in medium work — only 50–80 g per day for a 1,000 lb horse.

Does it contain soy?

Yes — soy flakes are a core protein source. It is not soy-free. It is alfalfa-free, with no vitamins or minerals added.
