Mycotoxins are often
present in raw materials and compound feeds
and have a large impact on animal performance. Over 300 mycotoxins are identified, and a large number is still unknown. Aflatoxins (AFLA), T-2 toxin (T2), ochratoxin A (OTA), and fumonisins (FUM) are the most often occurring mycotoxins in poultry feed and in many cases a combination of these mycotoxins is found. The impact of multiple mycotoxin presence in feed is often underestimated, since they can have a synergistic effect.
