Abstract A 56 day experiment was conducted to determine the effect of different dietary levels of palm oil sludge on the growth performance, carcass trait, and economic cost of feeding local turkeys. Forty local poults (mixed sexes) were randomly assigned to five treatment groups with eight poults per treatment. Each treatment was replicated twice with four poults per replicate in a completely randomized design. The poults were fed commercial broiler starter ration containing 24% crude protein and 2800kcal/kgME for the first 6 weeks. Thereafter, five experimental diets containing varying levels of palm oil sludge were formulated and fed until the turkeys attained the age of 14 weeks. The experimental diets were designated T1,T2, T3, T4 and T5 with T1 containing 0% inclusion of palm oil sludge serving as control, while T2, T3, T4 and T5 had 5%, 10%, 15% and 20% levels of inclusion of palm oil sludge, respectively. The body weights of the turkeys were taken weekly for 8 weeks while the feed intake of the turkeys was recorded daily. The feed conversion ratio and daily weight gain of the turkeys were computed. At the age of 14 weeks, four birds per treatment were randomly selected, weighed and sacrificed for carcass and organ evaluation. Weights of eviscerated carcass, breast, thigh, drumstick, back, wing, head, shank, back, neck, liver, heart, gizzard, spleen, abdominal and visceral fat were recorded. The results showed that the final live weight, total weight gain, total feed intake and feed conversion ratio were significantly (P< 0.05) lighter than those of other treatments. The final live weight of birds on treatments 1,3,4 and 5 were 2010g, 1950g, 2050g and 1750g, respectively. The total weight gain on treatments 1,3,4 and 5 were 1730g, 1670g, 1770g, 1460g, respectively. The total feed intake of birds on treatments 1,3,4 and 5 were 4610g, 4560g, 4770g and 4410g, respectively. Feed conversion ratio values of 2.66, 2.72, 2.69 and 2.69 were recorded for birds on treatments 1,3,4 and 5, respectively. The cost of production showed that there were significant differences (p
