Abstract

The present study was conducted to evaluate feeding value of brown rice in Korean native beef steers (Hanwoo) fed concentrates and orchardgrass hay (50:50 on a wet basis) as a basal diet. Either 50% or 100% of corn in concentrates was substituted for brown rice, and ruminal fermentation characteristics, in situ degradability of feeds and in vivo digestibility of concentrate were investigated. The digestibility and nutritive values of corn and brown rice feeds were similar, whereas rumen degradability of brown rice was higher than that of corn. Compared with corn-based diets, the brown rice substitution decreased (P<0.05) ruminal NH3-N concentration, but did not affect rumen pH. Total volatile fatty acid content in ruminal digesta for the corn based diet was higher than those for the brown rice-contained diets. The brown rice substitution increased (P<0.05) the ratio of ruminal acetic acid to propionic acid (A/P) compared with corn-contained diets.Present results indicate that corn might nutritionally be substituted for brown rice as cattle feeds. In addition, we expect that relatively high A/P with brown rice may produce affirmative effects in rumen physiological aspect, particularly under the grain based feeding system for beef cattle in Korea.
