Supplementing beef steers consuming immature bluestem with 0, 1, 2, or 4
lbs of sorghum grain daily did not affect forage intake. Thus, total intake
increased as level of grain increased. Total dry matter, cell wall, and starch
digestibilities were mildly depressed with increasing grain. Rumen fill and rates of
passage were similar for all treatments, and differences in rumen fermentation
characteristics were minimal.
