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

¹

Screened feed that yielded reduced abundance of feed fines treatment.

²

Added fines feed that yielded increased abundance of feed fines treatment.

³

The standard error of the mean (SEM) n = 24 pens with 17 birds per treatment.

⁴

Nonapplicable.
