¹Data are least squares means of eight observations for each treatment, except for DDGS-2, for which data are the means of seven observations.

²DDGS = distillers dried grains with solubles (Flint Hills Resources, Wichita, KS); corn protein (Flint Hills Resources, Wichita, KS).

^a,bValues within a row lacking a common superscript letter are different (P < 0.05).
