Abstract The present work was undertaken to screen single and compound feed for mould and mycotoxins contamination. 155 samples of single and compound feed (40 samples of yellow corn, 22 wheat, 6 tibn, 17 soya beans, 27 hay, 13samples of poultry ration 10 samples of each broiler concentrates, meat and bone meal, and layer concentrates) were subjected to mycological examination. The isolated fungi from single feed samples represented ten genera. The most predominant genus in all types of single feed was Aspergillus species which was isolated from all samples. whereas, other genera were isolated in variable orders in the different single feeds. For instance, isolation frequency was in yellow corn samples, Aspergillus spp. was isolated from all samples (100%), followed by Rhizopus spp. (95%), Mucor spp. (45%) and Penicillium spp. (30%). In hay samples the predominant isolates were Aspergillus spp., followed by Penicillium spp., Cladosporium spp., Fusarium spp. and Alternaria spp. (93%, 93%, 70%, 65% and 49 %) respectively. In soya bean samples the predominant isolates were Aspergillus spp., followed by Penicillium spp., Mucor spp. Rhizopus spp Cladosporium spp., Scopulariopsis spp. and Alternaria spp. (100%, 75%, 24%, 23%, 18% and 17%) respectively. in wheat samples the main genera fungus isolated were Aspergillus spp. (96%), followed by Penicillium spp. (85%), Rhizopus spp. (450/0), Mucor spp. (27 0/0) |
