Mycotoxins and animal feed

Mycotoxins in animal feed

Animal production has made significant progress thanks to good management, improved nutrition and a focus on animal welfare. However, limiting factors can prevent adequate nutrition from being achieved, negatively affecting animal health and the financial situation of the farm.

Among these factors, the most important is usually the presence of mycotoxins in the raw materials. Animal nutrition specialists consider that the elimination of these metabolites in the raw materials of feed regimes is a new challenge for improving animal nutrition in particular and animal production in general.

What are mycotoxins?

Mycotoxins are the metabolites resulting from the mycotoxins that cause significant damage to crops, animals and humans, leading to illnesses and considerable economic losses.



Aflatoxins B1 produced by Aspergillus flavus and Aspergillus parasiticus are the most toxic and the most mutagenic; they are classified by the World Health Organisation and the International Agency for Research on Cancer as Group 1 cancers.




Negative effects of Aflatoxins B1 on animals:

  • Chez les monogastriques:

aflatoxin B1 affects many organs, tissues and the various systems of the animal, which reduces the performance of the latter. Numerous studies have demonstrated the adverse effects of aflatoxin B1 on poultry and pigs.

  • Chez les ruminants:

ruminants are known to be less sensitive to the negative effects of mycotoxins than non-ruminants. However, production (milk, feed or milk), reproduction and growth may be negatively modified when ruminants consume mycotoxin-contaminated feed over long periods.

Aflatoxin adsorbents

The application of preventive practices to control mycotoxins in general and aflatoxins in particular is not always effective in reducing their toxicity. Mycotoxin adsorbents are considered to be one of the most effective control strategies.

MYTA's sepiolytic argil is a 100% natural technological additive registered in the European Union under the number E 563 and marketed under the trademark ADCLAY for animal feed. Studies have shown that this additive is able to adsorb aflatoxin B1 with high affinity and stability. Consequently, its addition to aflatoxin-contaminated feed is effective in preventing its absorption in the gastro-intestinal tract of the animal: the toxin-adsorbing complex passes through the tract to be eliminated in the seals.
