Background  To reduce use of main feed ingredient like corn, soy bean meal (SBM) and wheat, alternative ingredients has been studied like copra meal (CM). Production amount of CM which has been high makes CM to be an alternative feed stuff. However, low digestibility on AA and low energy content by high fiber content can be an obstacle for using CM. This experiment was conducted to evaluate the effects of CM supplementation with  β -mannanase on growth performance, blood profile, nutrient digestibility, pork quality and economic analysis in growing-finishing pigs.    Methods  A total of 100 growing pigs ([Yorkshire × Landrace] × Duroc) averaging 31.22 ± 2.04 kg body weight were allotted to 5 different treatments by weight and sex in a randomized complete block (RCB) design in 5 replicate with 4 pigs per pen. Treatments were 1) Control (corn-SBM based diet + 0.1% of  β -mannanase (800 IU)), 2) CM10 (10% copra meal + 0.1%  β -mannanase (800 IU)), 3) CM15 (15% copra meal + 0.1%  β -mannanase (800 IU)), 4) CM20 (20% copra meal + 0.1%  β -mannanase (800 IU)) and 5) CM25 (25% copra meal + 0.1%  β -mannanase (800 IU)). Four phase feeding program was used: growing I (week 1–3), growing II (week 4–6), finishing I (week 7–9) and finishing II (week 10–12).    Results  In growth performance, there was no significant difference among treatments during whole experimental period. In growingI phase, G:F ratio tended to increase when CM was increased (P = 0.05), but ADG and ADFI tended to decrease in finishingII phase (linear,  P  = 0.08). Also, increasing CM reduced ADG (linear,  P  = 0.02) and feed efficiency (linear,  P  = 0.08) during the whole finishing period. In blood profiles, BUN was linearly increased as CM increased (linear,  P  = 0.02) at growingII period. In digestibility trial, there was no significant difference in dry matter, crude fat, crude ash and nitrogen digestibility. However, crude protein digestibility was decreased linearly (linear,  P  = 0.02). In economic analysis, feed cost per weight gain and total feed cost per pig were reduced in overall period when CM was provided by 25% (linear,  P  = 0.02).    Conclusion  CM with 0.1% of  β -mannanase (800 IU) could be supplemented instead of corn and SBM up to 25% without detrimental effects on growth performance and pork quality of growing-finishing pigs.
