Abstract
Ninety crossbred yearling steers were fed to compare corn and grain sorghum fed in drylot or on rye pasture with pasture only. Average daily gains for steers fed corn in drylot were similar to gains for steers fed grain sorghum in drylot and gains for steers fed corn on pasture were similar to gains for steers fed grain sorghum on pasture. Average daily gains were highest (P<.05) for steers fed either corn or grain sorghum in drylot, intermediate (P<.05) for steers fed either of the grains on pasture and lowest (P<.05) for steers on pasture without supplemental grain. Steers fed corn in drylot required 7.95 units of feed per unit of gain compared with 8.96 units of feed per unit of gain for steers fed grain sorghum in drylot. With the exception of dressing percentage, carcass characteristics for steers fed corn or grain sorghum in drylot were similar to each other but different (P<.05) from the three pasture groups. Returns to capital, land, labor and management per steer were $12.86 for drylot steers fed corn, $12.07 for steers on pasture without supplemental grain, $9.36 for pasture steers fed grain sorghum, $6.08 for pasture steers fed corn and $.56 for drylot steers fed grain sorghum.
