In the present study (250) samples of feed and feedstuffs collected from different places in Sharkia Governorate were examined mycologically. The collected samples were yellow corn (35), white corn (25), barley (20), poultry ration (40), rabbit ration(35), animal ration (30), concentrates (20), crushed corn (10), wheat bran (7), rice bran (3), cotton seed meal (15), hay (5) and soy bean meal (15) from these samples 70 grain samples were subjected for surface sterilization. F or isolation of fungi, steThe fungi recovered from samples six genera including Aspergillus (100%), Penicillium (37.64%) Fusarium (28.82%),Cladosporium (52.35%), Alternaria (19.41 %) and Mucor (30%). After six months of storage the fungal isolation were 7 genera including Aspergillus (100%), Fusarium (35.29%), Penicillium(17.06%), Cladosporium (46.47%), Alternaria (8.23%), Mucor (14.12%) and Scopulariopesis (1.18%). Concerning the frequency of isolation of Aspergillus species from examined feed and feedstuffs samples before storage were(79.41 %) Aspergillus flavus, (42.35%) Aspergillus niger, (25.29%) Aspergillus fumigatus, (20%) Aspergillus ochraceus, (18.82%) Aspergillus versicolor, (16.47%) Aspergillus nidulans, (14.70%)Aspergillus candidus, (13.53%)Aspergillus glaucus and (10.59%) Aspergillus terreus. After 6 months storage of samples, Aspergillus species were isolated in following pattern different rations as follows (75.88%) for
