marstall Senior-Aktiv is a cereal-free, easily digestible muesli, which is especially designed for the needs of old horses. It promotes the preservation and reconstruction of the body substance. At the same time it supports sluggish digestion and the immune system. Senior-Aktiv covers the partly increased need for vitamins and minerals in senior horses and stimulates chewing activity. This benefits both the stomach and the psyche. The deliberately starch- and sugar-reduced formula is also ideal for horses that are sensitive to metabolism.

Senior-Aktiv is a cereal-free structure muesli that specifically supports the maintenance of the musculature.

One of the most important goals for old horses is to maintain their muscles and body substance - especially during coat change and the cold season. Senior-Aktiv provides them with energy as well as with essential, easily digestible amino acids which the horse's body can utilise 100%.

For senior horses it is also important to support intestinal flora and intestinal activity. Only in this way can valuable ingredients from the feed reach the body. For this purpose marstall Senior-Aktiv contains besides traditionally used linseed also mannan-oligosaccharides and ß-glucans (short MOS). According to studies these components of brewer's yeast cell walls form an intact biofilm on the intestinal mucosa which serves as a protective barrier for harmful substances. At the same time, MOS bind mycotoxins and pathogenic germs in the intestine so that they can be excreted. MOS are also food for the good intestinal bacteria (prebiotic effect). Together these properties relieve the immune system.

Trace elements are added in an organic, i.e. highly digestible, form. Of course, the increased need of old horses for zinc and selenium as well as vitamin A and E has been taken into account. The grain-free Senior-Aktiv contains a lot of structure, but neither molasses nor alfalfa and is also ideally suited for horses with metabolic problems.

Moderate work

 approx. 300 to 450 g per 100 kg BW/day

Heavy work

approx. 450 to 550 g per 100 kg BW/day

Example feed per day for a 600 kg horse as a single concentrated feed in addition to hay

Light work

 approx. 1,0 kg to 1,5 kg

Moderate work

 approx. 1,5 kg to 2,5 kg

Heavy work

In case of hasty eaters, horses with feed envy, tooth problems etc. we recommend to feed Senior-Aktiv soaked. Then, for example, add 1 litre of warm or cold water to 1 litre of Senior-Aktiv and let it steep for 15 minutes.

Our marstall feeding experts recommend: marstall Senior-Aktiv can also be fed soaked as a mash if required. This is especially beneficial for horses that eat hastily, horses with dental problems or feed envy. For old horses that are no longer able to chew well, we also recommend our „Wiesen“products, soaked as a roughage substitute.

1 liter marstall Senior-Aktiv = approx. 400 g

Feeding advice

All specified feed quantities are to be given throughout the day in several small feeds.

Our recommendations assume a roughage intake (hay) of 1.5 kg per 100 kg body weight per day.

Tipps für alte Pferde

Bei Zahnproblemen

Senior-Aktiv kann natürlich auch eingeweicht verfüttert werden. Als Raufutterration bieten sich dazu eingeweichte Wiesen-Cobs an.

Darf ein bisschen mehr sein?

Die getreidefreie Ration kann mit Bergwiesen-Mash (ohne Getreide) ergänzt werden – das unterstützt die Verdauung zusätzlich. Benötigt das Pferd mehr Energie, eignet sich z. B. Lein-Distel-Öl.

Unser Tipp mit Getreide

Darf das Pferd auch im Alter Getreide bekommen, können Sie marstall Senior-Aktiv entweder mit Hafer, Gerstenflocken oder Maisflocken ergänzen oder unser Müsli Senior Plus füttern.
