Résumé
AIM: To observe the transfer of the digestive microbiota from sow to piglet, describe the impact of the sow's Salmonella shedding on this transfer and identify transferred populations that could be associated with the future Salmonella status of the piglets.
METHODS AND RESULTS: Salmonella shedding status of 19 sows was determined at the beginning and end of gestation. Four piglets were randomly selected from each sow. Using MiSeq, the microbiotas of the sows at the end of gestation and of their piglets 1 day before weaning were described. Results showed that the Salmonella shedding of the sows, the birth mother, the lairage room, the parity and the contamination of the lairage environment were associated to the microbiota of the piglets (permanova P < 0·05). Several genera were associated with piglets born from negative or positive sows.
CONCLUSION: There is a link between the microbiota of the sows at the end of gestation and the microbiota of their piglets at weaning, and the Salmonella shedding of the sow is associated with the microbiota of the piglets.
SIGNIFICANCE AND IMPACT OF THE STUDY: Salmonella status of the sows affects the microbiota of their piglets and could affect the long-term Salmonella colonization resistance of these animals and their health.
