¹ n = 24 pens per treatment (main effects); data were analyzed using repeated measurements; week was significant (P < 0.05), and no X × EB × Week interaction (P > 0.10).

²Xylanase activity was expected to be 15,000 EPU/g and inclusion rate was 0.01% according to the manufacturer’s recommendation.

³One gram EB was expected to contain 7,000 CU of cellulase, 5,000 U of β-glucanase, and 1,000 EPU of xylanase; the inclusion rate of EB was 0.01% according to the manufacturer’s recommendation.
