Suckling piglets face the hurdle of pathogenic inversion before the full development of their gastrointestinal tract. The provision of Lactobacillus(L) salivarius guarantees resilient gut health, controls pathogens, increases microbiota, and fortifies intestinal structure. We evaluated the effect of L. salivarius LS144 probiotic given to suckling piglets through the post-weaning stage on the gut microbiota, intestinal morphology, and growth performance. 120 three-day-old crossbred (Landrace × Yorkshire × Duroc) piglets were assigned to four dietary treatments on the basis of initial body weight. The NN group was not supplemented with the probiotic in both the suckling and post-weaning phases, the NP group was supplemented with the probiotic during the post-weaning phase, the PN group was supplemented with the probiotic only during the suckling phase, and the PP group was supplemented with the probiotic during both the suckling and post-weaning periods. Results revealed that the average daily gain was higher (ppppppL. bacteria was greater in both the PN and PP groups compared to the NN treatment in the duodenum (ppppL. salivarius in suckling piglets continued to post-weaning could establish appropriate intestinal microbiota, improve feed intake, and increase the villus height, which translates to improved growth performance during this critical period in piglet's life.
