Fig. 7From: Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steersCorrelation network between liquid and solid bacterial OTUs and ruminal fermentation variables according to each RFI group. The edges represent significant associations, as determined by Spearman’s rank correlation (P < 0.05). These analyses were performed using OTUs that were shared by at least 50% of the steers in each feed efficiency group. Biochemical parameters: molar proportion of acetic, Ace; propionic, Prop; succinic, Suc; butyric, But; isobutyric, Isobut; valeric, Val; and isovaleric acids, Isoval; acetate-to-propionate ratio, Ace/Prop; total concentration of these volatile fatty acids, VFAt; ammonia concentration, NH3; and ruminal pH)Back to article page
