A total of 120 weaning pigs [(Landrace × Yorkshire) × Duroc] with an average body weight of 8.95 ± 0.88 kg were used in this study to investigate the influence of supplementation of combined flavor and sweetener. The diets included: 1) TRT1, basal diet, 2) TRT2, TRT1 + 500 mg/kg flavor, 3) TRT3, TRT1 + 150 mg/kg sweetener, and 4) TRT4, TRT1 + 500 mg/kg flavor + 150 mg/kg sweetener. The TRT4 treatment produced a higher average daily gain (ADG) than that in the other treatments on d 0 - 14 and the whole experimental period (p < 0.05). The TRT1 and TRT2 treatments gave a lower average daily feed intake (ADFI) than that of TRT4 on d 0 - 14 and d 0 - 42 (p < 0.05). On d 15 - 42, TRT4 had a higher ADFI than that of TRT1 (p < 0.05). Compared to TRT1, dry matter (DM), gross energy (GE), and nitrogen (N) digestibility increased in pigs fed the TRT4 diet (p < 0.05) on d 14. Serum norepinephrine concentration in TRT1 treatment was higher (p < 0.05) than that in TRT4 treatment at 72 h after weaning. On d 0 - 7, diarrhea score decreased in TRT4 treatment compared with TRT1 and TRT2 treatments. In conclusion, flavor and sweetener complex addition improved ADG and ADFI as well as DM, N, and GE digestibility in weanling pigs. This supplementation in pigs’ diets decreased the serum norepinephrine concentration at 72 h after weaning and the diarrhea score during the first week of weaning.
