From a total of 80 fertile eggs incubated naturally by female ducks, healthy sexed ducklings (n = 64, 32 males and 32 females ducklings) were randomly selected and allotted to four dietary treatments with four replicates, in a completely randomized design in order to evaluate the effect of varying levels of palm kernel meal (PKM) on performance of ducklings. The dietary treatments comprised R0-control ration, R50-50% PKM replacement, R75-75% PKM re-placement and R100-100% PKM replacement of soyabean meal. The main results revealed that the apparent digestive coefficients of dry matter (81.12%), organic matter (83.98%) and NDF (81.10%) were higher with the ration in which 50% (R50-50% PKM replacement of soyabean meal) of soybean was replaced by palm kernel meal. The highest feed intake in male was recorded with the ration containing 75% (R75-75% PKM replacement of soyabean meal) of palm kernel. This same ration (R75-75% PKM replacement of soyabean meal) equally induced the highest live weight and weight gain in females. The experimental design and arrangement is a 2 × 4 factorial arrangement with two sexes and four levels of PKM. In males, the control ration without palm kernel meal induced the highest live weight and highest cumulative weight gain. The lowest feed conversion ratio (p 0.05) affected by the incorporation of palm kernel meal into the diet. Urea serum content tends to decrease with the increasing level of palm kernel meal in feed. In conclusion, soybean meal can advantageously be repla
