Gastrointestinal diseases in weaned piglets are a frequent cause of high morbidity and mortality domestic pigs. The use antibiotics is problematic due to increasing antibiotic resistance bacterial populations, for which reason the suitable probiotics highly recommended maintain animal health welfare. In this study, 57 strains biologically safe lactic acid bacteria (LAB) bifidobacteria originating from gastrointestinal tract (GIT) pigs were identified characterized terms their probiotic properties potential piglets. These divided into two sets based on origin - GIT wild boars (n = 41) 16). Strains obtained exhibited greater taxonomic diversity compared isolates While searching coding sequences (CDS) encoding bacteriocins bile salt hydrolases (BSH), no significant difference was detected between tested groups. On other hand, CDS adhesinlike factors more dataset isolated than Moreover, carbohydrateactive enzymes (CAZymes) carried genomes boars. Utilization important selected carbohydrate substrates, such as starch, D-raffinose, D-mannose, Dcellobiose gentiobiose, confirmed by API testing. Antimicrobial activity against at least one five pathogens found 51% boar but none This suggests that intestinal microbiota could serve promising source
