摘要：AbstractA total of 435 samples from feedstuff (130 samples of commercial ration feed storage from 1–30 days, 77 samples of commercial ration stored higher than 30 days, 57 samples from each of, derris, grind mixture, Tibn and wheat bran) were collected from the feed store houses of private farms located at the desert regions of Ras Sudr at South Sinai and Elameria area at Alexandria Governorate, from December 2012 to May 2014. The collected samples were analyzed for fungal growth. The results revealed that, the main moulds observed in the ruminant feeds werePenicilliumspp.,Aspergillus (A) flavus,Cladosporiumspp.,Mucorspp.,Trichodermaspp.,A. niger,Alternariaspp.,Rhizopusspp.,Fusariumspp.,A. fumigatesandA. terreus. In addition, the winter season was of higher incidence for moulds isolation than summer season. The most toxigenic aflatoxins secreted byAspergillus flavusinclude Aflatoxin B1, Aflatoxin B2, Aflatoxin G1 and Aflatoxin G2. The results of biological treatment of Aflatoxins usingSaccharomyces (S) cerevisiae, showed that, the addition ofSaccharomyces cerevisiaeat a level of (1 × 106) cfu.ml−1and (1 × 109) cfu.ml−1decreased the level of concentration of aflatoxin B1, B2, G1 and G2 and the level of (1 × 109) cfu.ml−1was more efficient in reducing aflatoxins than the lower concentration.
