FIGURE 1.
Fecal microbiota at birth in heifer calves born to cows offered a control diet (CON, n = 13) or CON supplemented with ethyl-cellulose rumen-protected methionine (MET, n = 13; Mepron® at 0.09% of diet DM; Evonik Nutrition & Care GmbH, Germany) during the last 28 days of pregnancy. (A) Non-metric multidimensional scaling (NMDS) plot of fecal microbiota profile. (B) Alpha diversity indices. (C) Cladogram of LEfSe analysis shows the overrepresented microbial populations. Taxa are significant from LeFSe (P ≤ 0.05 and LDA cutoff > 3.0). (D) Histogram of the LDA scores reveals the most differentially regulated metabolic pathways in fecal microbiota at KEGG levels 3.
