Call for Price

marstall Gastro-Müsli was designed according to the latest scientific findings for horses with sensitive stomachs or stomach problems. In addition, nervous and thin horses also benefit from the cereal-free, stomach acid-buffering and at the same time optimally digestible recipe. The molasses-free muesli is very tasty, as horses with stomach problems are often fussy.

Thanks to the Allgäu hay fibres and soft Timothy chaff, Gastro-Müsli has a high structure content. This stimulates the chewing activity and thus promotes the formation of saliva. This, together with the added bicarbonate, buffers the stomach acid. The cereal-free recipe without molasses also helps to avoid extreme acidity in the stomach.
Grape marc brings anti-inflammatory polyphenols into marstall Gastro-Müsli, antioxidants and omega-3 fatty acids support this effect. Mannan-oligosaccharides and ß-glucans support a healthy gastro-intestinal environment by promoting the natural biofilm on the intestinal mucosa, strengthening the immune system and binding mycotoxins. They also have a prebiotic effect. The high content of small intestinal digestible protein in this gastric muesli supports the muscles and helps especially thin stomach patients to regain more body mass.
As stress and stomach problems often go hand in hand, Gastro-Müsli contains extra magnesium. Not only nervous horses benefit from this, as magnesium is also important for muscle relaxation.
