Average number (line) of fecal pellets ingested by pups in the nest from 2 to 20 d after birth of rabbits having free access to mother feces in the nest (FM, control group), whose fecal ingestion in the nest was impaired (NF), or that had only access to feces from foreign does receiving either no antibiotics (FF) or medicated with tiamulin and tetracyclin (FFab). Bars indicate the number of feces available in the nest for pups.

Principal component analysis (PCA) projection on the first (PC1) and the second (PC2) PC of bacterial community taxonomic profile at the family level from 454 pyrosequencing run of rabbit cecal samples. The 4 plots illustrate the same analysis performed on the whole data set (n = 128 rabbits). The marks relate to the 4 experimental groups of rabbits having free access to mother feces in the nest (+, FM, control group), whose fecal ingestion in the nest was impaired (○, NF), or that had only access to feces from foreign does receiving either no antibiotics (▲, FF) or medicated with tiamulin and tetracyclin (■, FFab), and numbers indicate the age of rabbits at sacrifice. The numbers shown in parentheses correspond to percentage of explained variance of the PC.
