Effects of brewers’ spent grain (BSG) protein hydrolysates or antibiotics on the relative abundance (RA) of ruminal microbial at phylum (a) and genus (b) level. Treatments were: control (CON), basal diet; FlaH, basal diet + 1% FlaH (dry matter basis; DM); AlcH, basal diet + 1% AlcH; ANT, basal diet + 33 mg monensin + 11 mg tylosin/kg diet DM. The ANT reduced (P < 0.05) the RA of Firmicutes and Bacteroidetes and enhanced (P < 0.05) the RA of Proteobacteria at the phylum level; The FlaH treatment enhanced (P < 0.05) the RA of Prevotella, but reduced the RA of Selenomonas, Shuttleworthia, Bifidobacterium and Dialister as compared to the control. The AlcH treatment also had less (P < 0.05) RA of Schwartzia and Bifidobacterium than control. The ANT reduced (P < 0.05) the RA of Prevotella, Selenomonas, Shuttleworthia, Bifidobacterium, Lactobacillus and Dialister, and increased RA of Succinivibrio compared with control
