Popis: Summary Rotational and strip grazing were compared under uniform stocking rates on six acres of irrigated bromegrass ( Bromus inermis ) in 1959, 1960, and 1961. Total digestible nutrient (TDN) utilization was greater under rotational grazing throughout the experiment. Total herbage production, however, was also higher on the rotationally grazed paddocks the first two years of the trial. Fecal concentrations of plant pigments were used to estimate digestibility of herbage selected daily by two cows under each system in 1960 and 1961. Milk production was significantly (p
