Fig. 4. Neutral and acid detergent fiber (NDF, ADF) and crude protein (CP) concentrations of alfalfa and bermudagrass pasture during the 2000 and 2001 grazing seasons in Hope, AR. The value of x in regressions was the number of weeks after 20 March. Each tick mark on the x axis represents 1 wk. Regressions for 2000 were nonsignificant. Regressions for 2001 were calculated using only data from the rotational stocking management period (30 June–18 September) and were all significant at P < 0.001. Vertical lines are standard errors.
