Thirty two crossdreed (Large White x Mong Cai) pigs with an average initial live weight of 20 kg were fed one of 4 diets supplementing 0, 0.1, 0.2 and 0.8 percent(sa DM) Dl-methionin. The experiment was arranged as CRD with 4 replicates. The results show that with increasing Dl-methionin levels daily gains increased and feed conversion ratios decreased significantly (P less than 0.05), but not effect on feed intake (P0.05). Feed costs for daily gain were reduced from 3 to 9 percent for Dl-methionin diet compared to the control diet. In conclusion, supplementation of Dl-methionin level of 0.2 percent (as DM) in ensiled cassava root - based diets gave the best results on performance and economic efficiency.
