Weaning stress causes substantial economic loss in the swine industry. Moreover, weaning-induced intestinal barrier damage and dysfunction of gut-liver axis are associated with reduced growth performance piglets. Metasilicate-based alkaline mineral water (AMW) has shown potential therapeutic effects on gastrointestinal disorders; however, mechanisms involved their overall have not been explored. Here, sodium metasilicate (SMS) was used to prepare metasilicate-based AMW (basal + 500 mg/L SMS). A total 240 newly weaned piglets were allocated Control SMS groups (6 replicate pens per group 20 pen) for a 15-day trial period. Histopathological evaluations conducted using hematoxylin eosin staining. To analyze composition gut microbiota, 16S rRNA PacBio SMRT Gene Full-Length Sequencing performed. Western blotting immunofluorescence employed assess protein expression levels. Our results indicated that effectively alleviated colonic or liver morphological injury inflammatory response, as well cholesterol metabolism disorders. Further analysis showed promoted deoxycholic acid (DCA) biosynthesis by increasing abundance Lactobacillus_delbrueckii colon (P < 0.001). This consequently improved through DCA-secondary bile (SBA) receptors (SBAR)-nuclear factor-kappaB (NF-κB)/NOD-like receptor family pyrin domain-containing 3 (NLRP3) pathways. Growth parameters, including final body weight = 0.034) average daily gain 0.001), significantly higher than those group. Therefore, maintains homeostasis regulating microbiota-mediated SBA-SBAR pathway under weaning stress. research provides new strategy mitigating stress-induced
