Abstract

A metabolism trial was conducted to evaluate rumen pH, digestibility, and ruminal VFA concentrations of steers fed 25% CaO treated or untreated cobs, wheat straw, and corn stover. Treated diets had greater digestibility of DM, OM, and NDF compared to untreated diets. Substituting 15 percentage units of corn and 10% roughage with 25 percentage units of 5% CaO treated cobs, wheat straw, or corn stover resulted in similar DM digestibility, rumen pH and VFA concentrations.
