The interaction between corn processing method and condensed distillers solubles (CDS) was evaluated using either steam-flaked corn (SFC) or dry rolled corn (DRC). As CDS replaced corn at either 15 or 30% of the diet DM, DMI intake decreased quadratically for both SFC and DRC. Within DRC- based diets, ADG increased quadratically with 15% CDS being greatest and F:G improved quadratically with 30% ... [Show full abstract] inclusion being best. When SFC was used as the grain source, ADG increased linearly and F:G improved quadratically with increasing levels of CDS. A greater performance response was observed with SFC compared to DRC when feeding increased levels of CDS.
