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 cron.
