^a–cMeans within a row with different superscripts are significantly different (P < 0.05).

¹Treatments: CK = basal diet; PAM = basal diet supplemented with 3.4 g·sheep⁻¹·d⁻¹ of A. mongolicum Regel powder extract; AM = basal diet supplemented with 10 g·sheep⁻¹·d⁻¹A. mongolicum Regel powder; RAM = basal diet supplemented with 10 g·sheep⁻¹·d⁻¹A. mongolicum Regel extract residue.

² A. mongolicum Regel extracts = A. mongolicum Regel extract and residue.

³For each treatment, the taxa with relative abundances greater than 0.5% and within the top 5 relatively abundant taxa were defined as the predominant taxa at each taxonomic level f = family; g = genus.

⁴Dominant taxa were defined as the taxa with total relative abundances greater than 0.5% at the family and genus levels.
