Nine genera (Veillonella, Aerococcus, Bergeyella, Prevotella, Psychrobacter, Kurthia, Enterococcus, Acinetobacter and Facklamia) within the oropharyngeal microbiota were significantly associated with ADG at 11 days of age (FDR < 0.05).
[ ]; The names in square brackets [ ] within the Greengenes database are still contested at that taxonomic level.
ADG, average daily gain; logFC, log fold-change; logCPM, log counts per million; LR, likelihood ratio; FDR, false discovery rate (adjusted p-value).
