CON = control; AMR = Allium mongolicum Regel; AWE = the water-soluble extract of AMR; AFE = the fat-soluble extract of AMR.

^{a, b} Within a row, means with different superscripts differ significantly (P < 0.05) as determined by Tukey's test.

¹CON group was fed the basal diet.

²AMR group was fed the basal diet supplemented with AMR at 10 g/d per lamb.

³AWE group was fed the basal diet supplemented with AWE at 3.4 g/d per lamb.

⁴AFE group was fed the basal diet supplemented with AFE at 2.8 g/d per lamb.
