n = 14. CON: control group, FMT: faecal microbial transplantation group, CON = piglets in the CON group were fed empty capsules, iNOS: inducible nitric oxide synthases, eNOS: endothelial nitric oxide synthases.
^a,b In the same row, values with different letter superscripts indicate significant differences.
