Experiment was carried out to study the effects of using palm kernel meal (PKM) in place of corn meal (CM) on the growth performance and cost of production of growing pullets. In a completely randomized design. two-week old Isa Brown chicks were randomly allocated to 21 cages with 20 chicks/cage. Seven experimental dietary treatments (CM based (control), 10 percent PKM, 20 percent PKM, 30 percent PKM, 10 percent PKM + methionine and lysine, 20 percent PKM+ methionine and lysine and 30 percent PKM+ methionine and lysine were fed to the chicks (3 cages/treatment) until they reached 16 weeks old. There was no significant difference in feed intake among the several feeding regimes. However, the superiest diet for body weight, weight gain and feed conversion rates was the 10 percent PKM+ methionine and lysine. This treatment was not significantly different from other methionine and lysine supplemented groups, but was significantly (P LT 0.05) higher in body weight and weight gain than those groups fed control and 10 percent PKM diets. The pullets fed 20 percent and 30 percent PKM diets supplemented with methionine and lysine had simililar (P GT 0.05) results in the above parameters to the control group and the group fed 10 percent PKM. Pullets fed 20 percent and 30 percent PKM without methionine and lysine supplementation had significantly (P LT 0.01) poorer growth performance compared to other groups. For cost of production and mortality, the cost of production increased with the increasing level of PKM inclusion in the diet and the average mortality of pullets in this experiment was about 3.09 percent. From these findings, it is suggested that 10 percent with amino acids supplementation is the optimum substitution for CM in the diet of growing pullets. With amino acids supplementation, the PKM substitution can be increase to 30 percent and the amount of CM reduced by about 56 percent of the control diet with no significant adverse effects on the pullet performance.
