^a,bMeans within a column lacking a common superscript differ (P ≤ 0.05).

Apparent metabolized energy corrected for protein.

Feed soybean meal factors, high-CP soybean meal 60% (HSBM), and low-CP soybean meal 48% (LSBM).

Feed fine abundance factors, increased feed fines (IFF), and reduced feed fines (RFF).

⁴

The enzyme in diet factors, 200 ml/mt enzyme cocktail added, Rovabio Advance, Adisseo France S.A.S, Antony, France (WENZ), and no enzyme added (NENZ).

⁵

Feed conversion ratio corrected for mortality using BWG as the numerator.
