1Alpha diversity differences between different sample sources (rumen content vs. rumen papillae) were tested with Friedman’s test.
2Alpha diversity differences between different variables (healthy vs. liver abscess, Steer vs. Heifers, and limonene vs. no limonene) within rumen content or rumen papillae samples were tested with Wilcox test.
