Mycotoxins and vitamin D in poultry
Mycotoxins interfere in the vitamin D metabolism leading to poor calcium absorption, causing Lameness. Does anyone agree to this point?
Yes, I agree with the statement. It is already proven that mycotoxins such as aflatoxin, ochratoxin, etc., can interfere with vitamin D/calcium/phosphorus metabolism.
Ram Singh Thank you for your valuable insight, sir.
This is very interesting. But , we understand and know that one important quality of mycotoxin binders is that they do not bind or hamper the availability of vitamins including vitamin D, otherwise, egg shell formation and skeletal formation would be impaired. In this situation, therefore, the nutritionist should watch the type of ingredients and the level of mycotoxin contamination in them, in order not to inform or warrant using higher levels of mycotoxin binders in the feed. This would not only reduce feed cost but enhance feed quality and efficiency.

Such "undesired adsorption" is something few people seem to think much about. And yet, it is why we do not use activated carbon, for example, which is great at adsorbing mycotoxins of all kinds but also binds nutrients of all kinds.
It is this selectivity that differentiates the different sources of bentonite around the world, with Ca-bentonites being more selective than Na-bentonites.
Interesting. Would anybody know what the maximum level of Aflatoxin should be (say roughly over a week) to avoid the interference? I would prefer to have data from experiments without binders.
