The objective of this study was to assess the mycotoxigenic mould contamination on proximate composition of poultry feeds. Aspergillus flavus, A. parasiticus, A. ocheracus and Fusarium verticilloides were the toxigenic moulds used to determine their effect on nutritional parameter of poultry feeds. The results of the chemical composition of the poultry feed before and after contaminated with toxigenic moulds showed that the uncontaminated feed contained high protein content (30.85%), ash (6.42%) and fibre (13.60%) contents while the moisture (11.23%) and lipid (21.51%) reduced when compared with contaminated feeds. High carbohydrate content (20.78%) was recorded for the feed contaminated with A. parasiticus. The reduction in the toxigenic fungal loads with increase in the protein content in the uncontaminated feed showed that the low incidence of toxigenic molds could suggest the safety of the feeds for poultry feeding.
