Synopsis: Coastal bermudagrass was harvested at 3-, 5-, and 7-week frequencies and pelleted. Cows fed the younger pellets and/or the higher level of concentrates produced more milk and gained more weight. Forage consumption and milk composition were not affected by the treatments. No interactions were significant. The younger forage contained more protein, but yielded less dry matter per acre.
