The Food and Agriculture Organization of the United Nations
(FAO) estimates that 25% of grain is contaminated with mycotoxins
globally each year, and, on average, 2% is not edible. Ingestion of
such contaminated grain can result in poisoning, disease and even
death in a large number of animals, causing huge economic losses
to the food industry and animal husbandry. Among these mycotoxins,
the most serious contamination is caused by aflatoxins (AFs)
(Feng et al., 2014). Aflatoxins are the secondary metabolite produced
by Aspergillus flavus, Aspergillus parasiticus, Aspergillus
nomius and Aspergillus pseudotamarii, is extremely toxic, mutagenic
and carcinogenic, and is recognized to be the most harmful
mycotoxin. In recent years, AFs contamination in poultry feed have
become increasingly serious, and severely affects the development
