Twenty-four 10-d-old entire male piglets (4\u00b73 (<jats:sc>sd<\/jats:sc> 0\u00b759) kg body weight) were fed an infant formula (IF) (control) or IF supplemented with 1\u00b73 \u00d7 10<jats:sup>5<\/jats:sup> (low dose) or 7\u00b79 \u00d7 10<jats:sup>6<\/jats:sup> (high dose) colony-forming units HN001 per ml of reconstituted formula (<jats:italic>n<\/jats:italic> 8 piglets\/treatment). After 24 d, piglets were euthanised. Samples were collected to analyse the histology and gene expression (RNAseq and qPCR) in the jejunal and ileal tissues, blood cytokine concentrations, and blood and faecal calprotectin concentrations. HN001 consumption altered (false discovery rate &lt; 0\u00b705) gene expression (RNAseq) in jejunal tissues but not in ileal tissues. The number of ileal goblet cells and crypt surface area increased quadratically (<jats:italic>P<\/jats:italic> &lt; 0\u00b705) as dietary HN001 levels increased, but no increase was observed in the jejunal tissues. Similarly, blood plasma concentrations of IL-10 and calprotectin increased linearly (<jats:italic>P<\/jats:italic> &lt; 0\u00b705) as dietary HN001 levels increased. In conclusion, supplementation of IF with HN001 affected the architecture and gene expression of small intestine tissue, blood cytokine concentration and frequencies, and blood calprotectin concentrations, indicating that HN001 modulated small intestinal tissue maturation and immunity in the piglet model.<\/jats:p>","DOI":"10.1017\/s0007114523002830","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T07:26:54Z","timestamp":1701847614000},"page":"1289-1297","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":4,"title":["The
