¹The control group was fed basal diets without the addition of FEO0, and the treatment groups were fed basal diets supplemented with 50, 100, 200, and 400 mg encapsulated FEO/kg (FEO50, FEO100, FEO200, and FEO400, respectively).

²Pooled standard error of the mean.

³European Production Efficiency Factor, EPEF: [viability days 0 to 42 (%) × BW at day 42 (kg) × 100]/[age (d) × FCR days 0 to 42].

Mean values with different superscripts (^a,b) within the same row are statistically different at *P < 0.05 and/or **P < 0.01.
