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.

³Taxa with low relative abundances were defined as taxa with total relative abundances less than 0.1% at the phylum, class, and order levels or less than 0.5% at the family and genus levels p = phylum; c = class; o = order; f = family; g = genus.
