The need to reduce cost of production of meat has necessitated the use of plant materials with medicinal properties as feed additives capable of minimizing the influence of pathogenic microbes and improving performance of the animal through better feed utilization. The study was conducted to assess the performance and carcass traits of weaner pigs (8 weeks old) fed powdered wonderful kola (Buchholzia coriacea) seed as a dietary supplement at 0, 5, 10, 15 and 20g/kg feed for treatments 1, 2, 3, 4 and 5 respectively. Sixty (60) weaner pigs of mixed sexes were randomly allotted to five (5) dietary treatments of three replicates each. Record of feed intake and weekly weight were documented and used to determine average daily feed intake, daily weight gain and feed conversion ratio. After six weeks feeding trial, feacal samples were collected and processed for nutrient digestibility evaluation. Two animals per replicate were randomly selected, fasted, slaughtered, dressing and cut to parts for carcass evaluation. Blood samples were collected, before slaughtering and were used for blood analysis. Results showed significant differences (p<0.05) in terms of average final live weight (FLW), average weight gain (WG), feed gain ratio (FGR), dressing percentage (DP) and proportional weights of carcass cuts across all dietary treatments. Pigs fed diets supplemented with wonderful kola had better FLW, WG, FGR, DP and increased cut-parts proportions compared to the control group. Only ether extract that was significantly (P<0.05) reduced as supplementation level increased while the serum biochemical parameters were not (P>0.05) affected except ALT which gradually increased (P<0.05) as supplementation level increased. Pigs fed diet supplemented with 15g/kg wonderful kola had the highest value in all parameters measured. It can be concluded from the study that powdered wonderful kola seed could be used as an additive in weaner pigs’ diet up to 15g/kg diet.
