Microbiota composition at phylum and family levels for lines N and 61. Microbiota composition for lines N and 61 using raw counts after rarefaction at the phylum level (a), at the family level for the most abundant taxa (b) and at the family level for the least abundant taxa (c). The most abundant phylum is Firmicutes followed by Proteobacteria and Bacteroidetes. There is no significant difference at the phylum level between lines. At the family level we observed, with decreasing abundances, Ruminococcaceae and Lactobacillaceae, followed by Enterobacteriaceae, Clostridiales and Bacillaceae
