Notes:

Sheep were fed 0, 0.8, 1.6, or 2.4% MOS (n = 6 per treatment). The mean digestion results are shown for each treatment over the 6-day collection phase of the study.

MOS, mannan oligosaccharides.

SEM, standard error of the mean.

⁴

DM, dry matter.

⁵

OM, organic matter.

⁶

NDF, neutral detergent fiber.

⁷

ADF, acid detergent fiber.

Means within rows with different superscript letters significantly differ (P < 0.05).
