The Hartog Digest is a roughage mix specifically created to support optimal digestive health. Because of its supportive additives and exceptionally low starch/sugar content this roughage mix is suitable for all horses, but especially for horses with digestive problems. The Hartog Digest provides a complete approach to all kinds of digestive problems by supporting the stomach as well as the hindgut including its essential microbiome.
Stomach health is supported by providing structure to stimulate chewing and thus saliva production. The increased amount of saliva, the added magnesium and the naturally high calcium content of lucerne help to neutralize stomach acid. Ideal to mix with balancers or concentrated feeds. This can support stomach health which is essential for horses prone to stomach ulcers.
In addition to stomach health, the Hartog Digest supports optimal hindgut health by providing healthy fibers, post- and prebiotics. Postbiotics are produced through precise fermentation of Saccharomyces cerevisiae to create hundreds of beneficial metabolites to directly support the immune system and gut health. Within every healthy horse is a healthy gut. The effectiveness of the postbiotics in the Hartog Digest (TruEquine™) have been proven in 17 scientific equine studies.
The postbiotics provide valuable metabolites to sustain a healthy immune system and limit digestive challenges during periods of stress like transport, competitions, vet visits, moving stables, seasonal changes, a changed ration and so on. The metabolites support intestinal cells, promote good bacteria and maintain the intestinal balance of the microbiome. Next to the added postbiotics, prebiotics from chichory are also added to provide additional nutrients to nourish the microbiota.
Hartog Digest provides an all-in-one solution to optimally support your horse’s digestive system. Its unique formula makes it the perfect supplement for horses with a sensitive digestion and related issues. No need for multiple supplements, Hartog Digest supports the entire digestive system in one easy-to-feed roughage mix. No more messy powders – just a complete, convenient, and highly palatable roughage mix that horses love!
Hartog Digest is low in sugar and starch and the recipe is free of both grains and molasses. With the added pieces of apple, carrot, beetroot, sunflower seeds and linseed oil, Hartog Digest is very palatable and suitable for difficult eaters.
