Forage for Cattle The majority of feed consumed by cattle should be forage. In fact, when a sufficient quantity of forage is available, cattle can be maintained on forage along with a supplemental source of salt and minerals. However, forage quality varies due to environmental changes.
The rations used in this trial provided two protein levels and two urea levels, % crude protein with or without % urea, and % crude protein with or without % urea. Six pens of cattle were fed each of these rations. Within these six pens, rumensin was added to the rations for three.
