Seven ruminally cannulated steers were used to evaluate fiber digestibility and rumen pH for diets containing 35 or 88% wet corn gluten feed (WCGF) or 35% wet distillers grains with solubles (WDGS). These diets were top-dressed with or without a direct-fed microbial (DFM). Interactions were observed for DM and NDF digestibility. Feeding 88% WCGF decreased DM digestibility, but NDF digestibility increased especially with the DFM. Rumen pH was greatest for steers fed 88% WCGF and lowest for steers fed 35% WCGF.
