Differential abundance of gut microbial transcripts assigned to SEED Subsystems.

Relative abundance of transcripts represents the number of sequences assigned to a subsystem for an individual animal divided by the total number of sequences for that animal. Mean relative abundance represents the average of these values in either the MF or FF treatment groups. A treatment group was considered to be enriched in transcripts assigned to a SEED subsystem if the p value was less than 0.05 for Level 1 subsystems and less than 0.03 for Level 3 subsystem. Subsystems with a mean relative abundance less than 0.0005 in both MF and FF groups were excluded. The table includes only a partial list of differentially abundant subsystems; a complete table is provided in Table S3.
