Maize is the preferred energy cereal used in poultry feed formulations because ofits high energy, low fibre and the presence of pigments and essential fattyacids. Consequently because it is a primary source of energy, due to its higherlevel of inclusion in poultry diets (60-70%), it contributes approximately 30%of the protein requirement of poultry. However, maize, like other cereals, isdeficient in certain essential amino acids, such as lysine and tryptophan.Therefore, to meet the requirements of these essential amino acids, farmers andfeed producers usually supplement poultry rations with synthetic amino acids.Quality protein maize (QPM), with almost double the lysine and tryptophanlevels, is no different from that of normal maize (NM) in terms of the quantityof energy and protein it contains. Consequently, inclusion of QPM in poultryformulations will enable the feed manufacturer to produce feeds requiringminimal or no additional supplementation of crystalline amino acids particularlylysine and tryptophan. This review examines the available research on thenutritional value of QPM in poultry for its commercial exploitation as a feedmaterial.
