    Aflatoxin is one of the groups of mycotoxins produced in animal feed by toxigenic fungi such as Aspergillus flavus, Aspergillus parasiticus and the rare Aspergillus nomius.These toxic fungal metabolites are found in feeds and foods. The aim of this study was to assess the knowledge, attitude and practice (KAP) of farmers and to quantify the level of aflatoxin AFG2, AFG1, AFB2 and AFB1 in Dairy and Beef cattle feeds and feed ingredients in Bishoftu and Adama districts. For this purpose a total of 60 livestock farmers and 60 livestock feeds of which 24 compound feed, 36 feed ingredients samples were purposively collected from Bishoftu and Adama districts. Aflatoxin analysis was performed by using high performance liquid chromatography with Immunoaffinity column clean up. The KAPs assessment revealed that awareness on factors that influence aflatoxin production, aflatoxin source and formation is very low among the dairy and beef cattle farmers. The contamination of aflatoxin AFB1, AFB2, AFG1 and AFG2 were found to be 20(83.3%), 17(60.8%), 62.5 and 17(60.8%), respectively in livestock compound feed whereas, the contamination of aflatoxin AFB1, AFB2, AFG1 and AFG2 in feed ingredients were found to be 20(55.6%), 23(63.9%), 21(58.3%) and 23(63.9%) respectively. The result of individual feed samples raveled that, all noug cake samples were contaminated with aflatoxin AFG2 with the range 1.09 to 114.49 μg/kg, AFG1: 6.34 to 735.98 μg/kg, AFB2: 2.69 to 151.71 μg/kg and AFB1: 16.85 to 980.28 μg/kg and total aflatoxin with range of 26.96 - 1953.14 μg/kg. The mean level of aflatoxin AFG2, AFG1, AFB2, AFB1 and total aflatoxin in noug cake were exceeded the maximum limit set by Food and Agriculture Organization, World Health Organization 20μg/kg and European Union 5μg/kg for dairy cattle feed. From this it can be concluded that noug cake feed was highly contaminated with all aflatoxins whereas wheat bran and wheat middling were less contaminated. These results suggest that extension education and risk mitigation should focus on mainly on noug cake and other feed ingredients to effectively reduce aflatoxin contamination in per-urban dairy and beef cattle feeds.
