Ceftiofur treatment of sows results in long-term alterations in the nasal microbiota of the offspring that can be ameliorated by inoculation of nasal colonizers

^* The number of the animals weighed at weaning was lower than the number of weaned animals due to the fact that the rooms in the nursery facilities were smaller and not all the weaned animals included in the study could be allocated in them
^#Only animals present at both timepoints were included
Control, non-treated piglets born to non-treated sows; TS, piglets born to treated sows; TP, piglets treated with ceftiofur born to non-treated sows; IP, inoculated piglets born to non-treated sows ; TS-IP, inoculated piglets born to treated sows
