Comparison of Corn Cobs and Hay in Ground, Restricted-Roughage Rations Affecting Milk Composition1

R. S. Emery, L. D. Brown and J. W. Thomas

Dairy Department, Michigan State University, East Lansing

ABSTRACT

Ground corn cobs were compared with ground hay in one trial and chopped hay in a second trial when each comprised 20% of the ration. Teed intake, milk production, and milk composition were measured. Ground corn cobs were a better roughage than ground hay and equal to chopped hay for maintaining feed intake and milk production. At 20% of the ration, none of these roughages maintained the pretrial milk fat concentrations.
