Fig. 2. Nonlinear regressions of concentrations of neutral detergent fiber (NDF) on time in storage for bermudagrass hay baled at moisture concentrations of 302 [high moisture (HM); solid bold line, squares], 265 [medium moisture (MM); dashed line, diamonds], and 219 [low moisture (LM); solid light line, circles] g kg^-1. Regression equations for HM [Y = 777 - 93.1e^-0.021t2; r² = 0.97; root mean square error (RMSE) = 9.4], MM (Y = 757 - 69.5e^-0.026t2; r² = 0.91; RMSE = 12.1), and LM (Y = 739 - 67.8e^-0.017t2; r² = 0.96; RMSE = 7.3).
