A total of 10 commercial layer farms in the stage of phase-I laying period (25 to 40 weeks) reared in raised platform caged house with uniform management wereselected for the experiment. In each farm, 4000 birds will be selected and divided into two treatment groups of 2000 birds each. The feed formulation with reduced crude protein level (15 per cent) compared to standard level of 17 per cent will be formulated by balancing the digestible amino acids (Lysine, methionine+cysteine, threonine, tryptophan, arginine, isoleucine and valine). Feed ingredients used in feed formulation were maize, cumbu, broken rice, soya bean meal, sun flower cake, deoiled ricebran, rapeseed meal, fish meal,etc. Based on the above study it could be concluded that crude protein reduction is one of the way to reduce feed cost in commercial layer chickens, but should be properly balanced with all the essential digestible amino acids rather than total amino acids basis. But the quality of feed ingredients, loss in body weight and egg weight is the area of concern.
