dc.description.abstractThe cellulolytic fungus Trichodermu reesei QM9414 was cultivated on spent brewery grains to partially hydrolyse the grains into soluble sugars and to alter the amino acid profile of the substrate. Aflatoxins were not detected in either the treated or the untreated spent grains. Amino acid profiles indicated that both the untreated and partially hydrolysed spent grains possess the entire range of essential amino acids required by poultry. Treated grains contained higher levels of lysine, histidine, glycine, methionine, phenylalanine, proline and alanine compared to those in untreated grains. The incorporation of treated grains at 8% and 12% into starter rations for broiler chickens in the first 4 weeks resulted in significant improvement in their growth and feed conversion ratio. There was no significant difference in feed conversion after 6 and 8 weeks of growth.
