| Abstract | ||
| The results of the detection of the fungi associated with seven poultry feed samples from different locations in Deila governorate revealed that the feed samples varied in the isolated fungi and the percentage of occurrence and the frequency of isolation and total fungal load. The following fungi were recorded: Alternaria alternata , Aspergillus flavus ,A.niger , Cladosporium cladosporioids , Fusarium oxysporum, Gonatobotrys simplex , Mucor sp. , P.cyclopium , P.expansum , P.griesofulvum , P.oxalicum , Ulocladium sp and Mycelia sterile fungi.The genus Penicillium recorded the highest percentage of occurrence (88.65%) in sample Di4 and the species P.griesofulvum recorded the highest percentage of occurrence in sample Di4 (88.65%). The genus Aspergillus come in the next which recorded the highest percentage of occurrence in sample Di3 (58.14%). Sample Di4 recorded the highest total fungal load (460 x 106 cfu) while sample Di6 recorded the lowest total fungal load (10 x 106cfu ). The results of toxigenic activity of 5 isolates of Asp.flavus showed that only 3 of them have toxigenic activity of aflatoxin production,and isolate. Di1 was the most toxigenic isolates. | ||
