Popis: Simple Summary The gut microbiota plays a key role in maintaining the overall health and homeostasis of mammals. Developing blends of nutrients that contribute to a diverse and balanced gut microbiota community thus contributes to improve pig health, particularly at weaning when rapid dietary and environmental changes occur. As shown in the present study, Tonisity Px, an isotonic protein drink that provides key nutrients for nourishing the enterocytes, increased the abundance of beneficial bacteria and decreased that of potentially-pathogenic bacteria when provided to piglets aged 2 to 8 days. This isotonic protein drink also improved the overall gut environment, both pre-weaning and post-weaning, as revealed by 16S rRNA gene sequencing and semiquantitative Escherichia coli culture. Abstract A healthy microbial community in the gut of piglets is critical to minimize the negative performance consequences associated with dietary and environmental changes that occur at weaning. Tonisity Px, an isotonic protein drink, is a potential alternative to balance the gut microbiota as it contains key ingredients for nourishing the small intestine. In the present study, 16 litters comprising 161 piglets were randomly allocated to a group to which Tonisity Px was provided from days 2 to 8 of age (TPX group) or to a control group, to which no Tonisity Px was provided. The TPX group also received Tonisity Px in the 3 days before and after weaning. At days 9, 17, and 30 of age, fecal and ileum samples were collected from piglets belonging to both groups and analyzed using 16S rRNA gene sequencing, semiquantitative PCR of Rotavirus serogroups, and semiquantitative Escherichia coli culture. Overall, Tonisity Px increased the abundance of beneficial bacterial populations (Lactobacillus and Bacteroides species) and reduced potentially pathogenic bacterial populations (E. coli and Prevotellaceae), in both the pre-weaning and post-weaning periods.
