Summary of Methods: Volesky measured the frequency and intensity of tiller defoliation under frontal, continuous and rotational grazing systems. The frontal grazing system utilized a push fence which allowed cattle access to small areas of ungrazed pasture while simultaneously excluding previously grazed areas from regrazing. After one day of grazing, the frequency and intensity of tiller defoliation was greatest in pastures managed with the frontal grazing system, intermediate in rotationally grazed pastures, and lowest in continuously grazed pastures. However, tillers were only accessible to cattle for a few days under the frontal grazing system. On average, season-long tiller defoliation frequency was lower and season-long stocking rate and forage production were greater in frontal grazing system pastures.
