This research wanted to determine the levels of adulteration by various class of Aspergillus and Penicillium contaminating poultry feeds and feed elements in three agro-ecological zones of Nigeria. The occupancy of fungi in feed sometimes leads to depressed consumption or total denial of feeds by poultry fowls. A total of 52 samples of feed (n=13) and feed ingredients (n=39) were composed across 3 agro-ecological zones (involving 6 states) of Nigeria. The splash plate technique was used to isolate miscellaneous mycological media. Utilizing visible and microscopic characteristics, the identity of isolates of Aspergilli and Penicilli was persistent. The feed samples were completely adulterated with Aspergillus class, while 63% were polluted accompanying Penicillium species. In the feed and feed supplements, nine Aspergillus species and five Penicillium variety were found. The best occurring fungal type was Aspergillus, specifically, Aspergillus niger and Aspergillus flavus variety were the highest happening species. The most accepted Penicillium species recognized from compounded fowl feed and feed ingredient samples was Penicillium glabrum. A number of Aspergillus and Penicillium species were present entirely of the feed samples (100%) in various amounts. All of the feed articles were contaminated, except that the samples of bone food, which were adulterated by 78%.
