Effect of Endosperm Type on Incremental Energy Value of Corn Grain for Dairy Cows

U.S. Department of Agriculture, Beltsville, MD 20705

ABSTRACT

The incremental energy value of corn grain representing two contrasting endosperm types was measured with lactating and nonlactating cows in energy balance experiments using indirect calorimetry. The energy values of increments of hard and soft types of corn were not different, but the energy values of both endosperm types were substantially lower for lactating than for nonlactating cows at maintenance intake. The average values for lactating and nonlactating cows were 2.32 and 3.38 Meal metabolizable energy/kg dry matter, 2.28 and 3.51 Meal digestible energy/kg dry matter, and .56 and .84 kg total digestible nutrients/kg dry matter. The average net energy value of the increment of corn grain for lactating cows was 1.34 Mcal/kg dry matter. Recommended energy values for corn grain are given as a function of intake and physical form.
