Re: Forum: Special Nutrients Mycotoxin binder product approved in Brazil
I have no doubt that Mycoad can bind aflatoxins and reduct the amount of M1 being transferred into milk. However, just because it is the first to be approved by LAMIC for use in Brazil does not mean it is the only binder capable of reducing the transfer of M1 to milk. A number of researchers have shown that some binders are very good for this while others are not good aflatoxin binders (Stroud et. al. Dietary Additives to Reduce Aflatoxin Transmission to Milk of Dairy Cows. J. Stroud, E. English, S. Davidson, B.A. Hopkins, G. Latimer, W.M. Hagler, Jr. , C. Brownie and L.W. Whitlow, J. Dairy Sci. Vol. 84 Supp. 1, pg 129.)
The opening comment is a bit misleading. I know of no data that even suggests that aflatoxins are detodified in the rumen. Aflatoxins are absorbed across the rumen wall, transported by the bolld to the liver. Here in the liver, aflatoxins are metabolized in to still toxic metabolites such as AFM1, which, with high enough levels in the blood, appears as AFM1 in milk.
The only mycotoxins detoxified to any degree in the rumen are the trichothecenes (DON, T-2, etc.) but not aflatoxins.
