Study on the age-dependent tissue expression of FUT1 gene in porcine and its relationship to E. coli F18 receptor

► We compared the age-dependent tissue expression of FUT1gene in piglets. ► Expression of FUT1 decreased from days 8 to 18, and then increased to day 35. ► FUT1 higher expression is beneficial to the formation of E. coli F18 receptor. ► Up-regulation of FUT1 was related to the sensitivity to E. coli F18 in piglets.
