  "abstract": "This study evaluated the effects of dietary supplementation with Bacillus licheniformis and Bacillus subtilis on the gut health and growth performance of weaning pigs. A total of 28-day-old piglets (n = 50 per group) were randomly assigned to four groups: CTRL (basal diet), BS (basal diet + Bacillus subtilis), BL (basal diet + Bacillus licheniformis), or BSL (basal diet + both Bacillus strains). After 28 days, pigs fed BSL had the highest body weight, although the difference was not statistically significant. Bacillus-treated pigs showed no differences in inflammatory cytokines or hematological characteristics, except for a reduction in cortisol levels in the supplemented groups. The genes encoding inflammatory cytokines were not significantly expressed among the groups. Intestinal morphology was significantly improved with villus height, villus/crypt ratio in BL (p < 0.05) and BSL (p < 0.01), and smooth circular muscle thickness showing notable increases in BS (p < 0.05), BL (p < 0.001) and BSL (p < 0.001). The tight junction proteins were significantly expressed higher in all Bacillus-treated groups, with BSL (p < 0.001) exhibiting the greatest improvement. Gene expression levels of ZO-1 and occludin were also significantly elevated in the ileum, with the most pronounced increases observed in BSL (p < 0.01). These results suggest that combining Bacillus subtilis and Bacillus licheniformis synergistically enhances intestinal morphology and barrier function, highlighting their potential as functional feed additives.",
