Dry matter intake and ruminal acid concentration were used to evaluate the influence of a dry-rolled corn (Control) and wet corn gluten feed diets (corn bran and steep liquor with distillers solubles, with or without solvent-extracted germ meal) on acidosis. Wet corn gluten feed without solvent-extracted germ meal promoted highest dry matter intake and daily minimum ruminal pH during grain adaptation. Control reduced intake and ruminal pH more than wet corn gluten feed diets, but increased propionate production. When solvent-extracted germ meal was included in wet corn gluten feed, intake was slightly reduced and ruminal pH was more variable.
