An adaptation strategy with wet distillers grains with solubles (WDGS) fed at decreasing levels (87.5 to 35%) was compared to a traditional grain adaptation with decreasing forage (45 to 7.5%) when adapting steers to a common finishing diet. Traditionally adapted steers had higher intake in steps one through three compared to steers adapted with distillers grains. However, DMI was not different between the two adaptation systems in step four, or when steers were on the finishing diet. Ruminal pH was higher for traditionally adapted steers compared to steers adapted to distillers grains in adaptation diets two and three. Ruminal hydrogen sulfide concentration did not appear to be a problem.
