Samples (n = 62) of two categories of animal feeds were collected from University Nangui Abrogoua experimental farms to determine some microbiological parameters by enumerating total bacteria, indicator bacteria, yeasts and moulds, and determining aflatoxins levels. Samples were constituted by granulate and concentrate feeds which contained soybean meal, cassava chip, maize, spent grains, cottonseed meal, dried plant materials, crushed snail shell and salt as main ingredients. Results showed that grasscutter feeds had high bacterial count (9.7 X 10⁶-1.3*10⁷ cfu/g). Identification of colonies from both types of feeds led to various species namely Enterobacter sp., Acinetobacter baumanii and Acinetobacter lwoffii for bacteria groups and Mucor sp., Aspergillus sp. and Penicillium sp. for the fungi. Mucor sp was the predominant mould isolates, representing more than 50% of isolates, followed by Aspergillus sp. (35%). Aflatoxins B1, B2, G1 and G2 were detected in almost all feeds. Aflatoxin B1 was the mycotoxin found in higher frequency (100%) and its level was highest in granulate feed samples. The information from the present study will contribute to set appropriate measures by Ivorian authorities and to develop traceability systems and establish a HACCP system as well as Good Agricultural Programme for Cote d'Ivoire.
