They can mostly be found in plant feedstuffs; however, it has seldom detected in animal or microorganism by-products. ANFs type and concentration varies with plant species, which protect them from predators, causing toxicity or gastrointestinal disruption.
The FAO has set up a portal to check the ANFs of different feed raw materials, where you can find as well the removal treatment: Anti-nutritional factors from feed ingredients
