Treatment and Experimental Design. A randomized
complete block design was used for Exp. 1. Dietary treatments
consisted of 0, 2.5, 5, 7.5, and 10.0% inclusion of
GLY (DM basis) in SFC-based diets (Table 1). Cattle were
blocked by BW (255 ± 3.6 kg) and randomly assigned to
treatment. Crude glycerin and supplemental cottonseed
meal replaced SFC in experimental treatments in an attempt
to balance all diets for CP (Table 1).
