Table 1. Numbers of samples per treatment with sufficient Gilliamella rimM reads for analysis after quality control filtering (n = 14 at each site per feeding group).

Diet treatment	TAMU	UT
POL	12	12
AD	3*** (0.0009)	4** (0.0032)
ADA	4** (0.0032)	9 n.s.

These are samples that amplified with specific primers and had > 500 reads after filtering out off target sequences. P-values are shown in parentheses. One-sided Fisher’s exact tests

** p < 0.01

***p < 0.001.
