Effect of RFIc and SI on OTU richness and alpha diversity at 97% similarity after rarefaction to 1,800 sequences per sample.¹

1<p>RFIc  =  residual feed intake in confinement; SI  =  stocking intensity; OTU  =  operational taxonomic unit.</p>2<p>Shannon index as calculated by Shannon and Weaver (1949).</p>3<p>SEM  =  standard error of the mean.</p

Effect of RFIc and SI on relative abundance of bacteria phyla.¹

1<p>RFIc  =  residual feed intake in confinement; SI  =  stocking intensity; relative abundance  =  percent of total bacteria sequences; phyla listed were detected at greater than 1% relative abundance averaged across all samples.</p
