In experiment 1, a total of 30 weaning pigs were allotted to three dietary treatments to check the palatability of the dietary feed. Diet treatments were as follows: reference diets = basal diets + 0.05% saccharin (50% Saccharin-natrium), TRT1 = 0.03% saccharin–neotame mix (50% Saccharine-natrium + 2% Neotame), TRT2 = 0.02% neotame (10% Neotame), and TRT3 = 0.02% saccharin–neotame mix (10% Saccharine-natrium + 10% Neotame). TRT2 group was significantly higher than other treatments in palatability (P < 0.05). In experiment 2, a total of 52 weaning pigs were allotted to four dietary treatments. In the average daily gain and average daily feed intake over 1 wk, the TRT2 group was significantly higher than the TRT1 and TRT3 groups (P < 0.05). The concentration of triglyceride in the blood was highest in the TRT1 treated group and the lowest in the TRT2 group (P < 0.05). The Lactobacillus was significantly higher in the TRT2 and TRT3 treatments compared with 0.05% saccharin (50% Saccharine-natrium) (P < 0.05). There was no significant difference in the number of Escherichia coli (P < 0.05). In conclusion, diets supplemented with neotame could improve palatability, and artificial sweeteners can affect nutrient digestibility, blood characteristic, and fecal microbiota.
