-6- SUMMARY Fattening steers fed rolled high moisture grain gained faster and more efficiently than those fed dry ground shelled corn. With cottonseed hulls as roughage, 12.2 percent less feed per 100 pounds gain was required with the high moisture corn ration. With Coastal Bermuda haylage, cattle gained 14.0 percent more efficiently with high moisture corn. An increase of $10.33 per head in return above costs of cattle and feed was obtained with high moisture corn as compared to dry corn. This increased return amounted to $10.18 per ton of high moisture corn or $11.49 per ton on a dry corn (14% moisture) basis. Although not directly compared, there was apparently no difference in response to dry corn reconstituted to 23 percent moisture and early harvested corn combined with 24.5 percent moisture. Citrus molasses topdressed on rations at the rate of 3.64 pounds per head daily (389 pounds per head for feeding period) resulted in increased gains, improved feed efficiency, lower cost gains, and greater returns above costs of cattle and feed. This response to citrus molasses was obtained with all rations in both trials.
