Effect of high RFI (HRFI) and low RFI (LRFI) phenotype on species presence, individual OTUs present, species richness, species evenness, and alpha diversity matrices (Shannon, Simpson) in the rumen solid phase.

	Solid
	HRFI	SD	LRFI	SD	P-value
HRFI n = 13 LRFI n = 11
Species	2440	446	2581	712	NS
Individuals	124701	26591	150851	50879	NS
Richness	207.91	35.54	216.29	53.79	NS
Evenness	0.63	0.05	0.63	0.06	NS
Shannon	4.89	0.45	4.96	0.51	NS
Simpson	0.97	0.02	0.97	0.02	NS

P-values are derived using a Student’s T-test to assess the differences between treatments.
