Binding

The bentonite used in X-Bond® Rumen has been tested in an in vitro trial to determine the adsorption of Aflatoxin B1 according to the EURL method. The binding rate was found to be 91.16% no matter the pH level - and is hence well above the EU requirements of 90%.

Deactivation

The deactivation powers of X-Bond® Rumen towards the mycotoxin DON and ZEN has been tested in vitro. DON is one of the most prevalent mycotoxins found in cattle feed and is known to impair the immune system. Cattle feed is typically kept in the rumen for 8-10 hours. At a normal passage speed the majority of DON and ZEN will be broken when X-Bond Rumen is added.

Supporting

One of the ingredients included in X-Bond® Rumen is Progut® - a dual function product from Hankkija that smooths the functioning of the rumen.
In the weeks just after calving the immune system has been stimulated and recovered. A long-term effect is also seen.
