Fungal isolates were found among 36 (57%) of the 63 Starter feed samples, 45 (71.4%) of the 63 Grower feed samples and 63 (100%) of the 63 Finisher feed samples. The fungal agents isolated from Broiler Starter Feeds, Aspergillus spp. 51 (70.8%) has the highest frequency of occurrence, followed by Fuserium spp. 12 (16.7%) and least is Rhizopus sp. 9(12.5%). Similarly, in case of Broiler Grower Feeds, Aspergillus spp. 66 (68.8%) has the highest frequency of occurrence, followed by Fuserium spp. 18 (18.7%) and least is Rhizopus sp. 12(12.5%). In case of Broiler Finisher Feeds, Aspergillus spp. 90 (69.8%) has the highest rate of occurrence followed by Fuserium spp. 24 (18.6%) and least is Rhizopus sp. 15 (11.6%) respectively.</p><p>International Journal of Natural Sciences (2014), 4(2) 38-41</p>
