What is Mycosorb for Horses?

Mycosorb for horses is a patented yeast cell wall extract for daily inclusion in horse feed.  It is rich in glucans that are known to bind mycotoxins. Mycotoxins can be present in pasture grass and the hay or haylage eaten by horses.

Variability in weather conditions whilst harvesting forage inevitably brings challenges where forage can contain many different moulds some of which can produce many and varied mycotoxins. Mycotoxins are produced naturally from all types of mould.  There are many different known mycotoxins. Mycosorb absorbs and locks up these toxins so that horse health can be maintained and they can be safely excreted without entering the bloodstream.

How does Mycosorb for horses work?

Mycosorb’s mode of action is supported by extensive published research and the product has been awarded several patents that protect its novel composition and proprietary production.

Mycosorb A + is the most broad-spectrum toxin-binder (including aflatoxins) and is derived from the inner portion of the yeast cell wall which contains both glucomannan and beta D-mannan combined with a small portion of alumina-silica. There is a synergistic effect of combining these two elements and this is patented. Research has shown it is effective in amounts as low as 0.05% of the diet.

Mycosorb has also been tested specifically against aflatoxin, ochratoxin and T-2, as well as in field trials of animal performance. Mycosorb has a helical or spiral structure which has an incredibly vast surface area. One gm of Mycosorb has 2 hectares of surface area, therefore it works at a very low feed rate at a wide range of pH throughout the intestine and has excellent capacity to mop up high concentrations of mycotoxins, pass through the digestive system, doing its job and then exit with the manure.

Feeding Mycosorb reduces mycotoxin absorption in the horse and contributes to the control of mycotoxins.

Will Mycosorb affect the absorption of other minerals and nutrients?

The short answer is no. Research on mycotoxin management has shown that Mycosorb A+ has a very limited ability to bind with vitamins and minerals. You can feed Mycosorb A+ together with your other feeds and supplements with confidence, without the worry of Mycosorb having any undesired effect on minerals and nutrient absorption.

    My mare had been hypersalivating and my vets thought it was due to toxins in the grass. Started her on the Mycosorb A+ and within a day all the slobbering had stopped. As the vets thought the problem was related to the weird weather we have been having, I will keep her on this until the weather changes!

    Another great product that addresses any mycotoxins my horses’ may ingest, especially living in The Netherlands and the amount of rainfall here.

    My fussy horse will eat it so that is something! I can’t yet comment on impact or not but tried it as a precautionary step.
