Utilization of quality protein maize in the diet of White Leghorn layers

Abstract Three experiments were conducted to determine the apparent metabolizable energy, digestible amino acid values and utilization of quality protein maize (QPM) vis-a-vis normal maize (NM) in White Leghorn layers. The nitrogen corrected apparent metabolizable energy of QPM was comparable (P>0.05) with NM. The apparent digestibility of lysine and threonine was higher ((P 0.05) due to treatments employed in the study. None of the egg quality parameters were affected (P>0.05) by replacement of NM with QPM in diet except Haugh unit and yolk colour. The Haugh unit and yolk colour index was higher (P 0.05) could be observed between QPM and NM + lysine supplemented group. These results suggested that feeding value of QPM was superior to NM in White Leghorn layers.
