This research was carried out by the IFS-UNILLANOS project in its experimental farm, located in the city of Villavicencio, Colombia. 64 crossbred pigs (Yorkshire and Landrace) of average weight 20 kg were allocated to 8 pens, each one with 8 animals. The four treatments were: C: 0.5 kg/d of soya bean meal (FSM) fortified with vitamins and minerals, M: 0.5 kg/d of FSM plus 8 --> 9 g/d of methionine, MB: 0.5 kg/d of FSM plus methionine and 0.93 --> 1.05 g/d B complex vitamins, and B: 0.5 kg/d of FSM plus B complex vitamins. The basal diet was the oil-rich fibrous residue from factory processing of african oil palm which was fed ad libitum. There were no significant effects of treatments (C, M, MB, B) on time to reach 90 kg (143, 138, 133 and 148 days), daily liveweight gain (480, 485, 504 and 466 g/d) and intake of the oil-rich residue (2.77, 2.75, 2.74 and 2.80 kg/d).
