Ruminants are not 100% protected by the Rumen!

Mycotoxins are well-known for their effects on monogastric animals. But ruminants, until recently, were considered as "protected" through the detoxification action of rumen flora. However, recent scientific studies show that only 20 to 30% of mycotoxins are really detoxified in the rumen. These studies have also highlighted the mycotoxins depressor effects on ruminants performance. Mor...

Thank you for article.

Rumen degradation of mycotoxins is decreased in current animal production system. It depends on passage rate, type of diet which influences the rumen environment. Usually , high producing animal having high dry matter intake especially concentrate, it favours high passage rate and less degradation of toxin in rumen, . Moreover, the rumen microflora activity also reduced by acidic condition.

Moreover, ruminants are exposure to multi toxin contamination. Because it consumes both concentrate and roughages ( silage is the major source).

So it is important to include the toxin binder in ruminants diets.

Thanks and Regards

Thanks for the Article. But it would be wise if the Ingredients (at least major) would have been discussed

Even though the micro-organisms in the rumen can detoxify the Mycotoxins and its metabolites, nonetheless it depends on the efficiency of rumen microbial environment.

For eg, 90% of Zearalenone(ZEN) can be converted to a-ZOL, which is 10X more toxic when compared with the parent toxin ZEN and only 10% can converted to ß-ZOL-less toxic, in the rumen.

For eg, Perhaps there will be a detoxifying mechanism for Aflaxtoxin B1 which is very toxic to liver. But only 10% of AFB1 get metabolized to Aflatoxicol which is less toxic. Major 90% will enter to the hepatic pathway and exerts the toxic effects on liver and kidneys.

Moreover, Silages are mostly affected by Fusarium sps and P.roqueforti. The only filamentous fungi detected viable even after 60 days of storage of silage is Penicillium roqueforti.

To summarize, Toxin binders are necessary and they play a crucial role in protecting the Animal's productivity.

Dr Amarnath and Dr. Thirumeignanam ,

I´d be glad if you could please give some more information about the ' Mycotoxin degradation in Ruminants and availability in milk'.

I will be looking forward to your reply

02/28/2012 | Montmorillonite, a nanoclay, has been found to have a mycotoxin binder affect, when added to feeds, what quanitity per metric ton is recommended?

02/29/2012 | Thanks for the article and participation from the animal nutritionist. Dear Dr. Amaranath , now large commercial farms are established having more than 100 dairy animals(Cows) and they have started feeding with brewer’s grain, silage and SO2 treated corn grain. Will you please discuss for the same on current topic?

Use of toxin binder in ruminants,is always disused considering cows but buffaloes responds differently as in
hormones ,is toxin binder the same case please highlight.
