Fig. 3. Nonlinear regressions of concentrations of acid detergent fiber (ADF) 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 = 391 - 61.3e^-0.022t2; r² = 0.93; root mean square error (RMSE) = 9.5], MM (Y = 368 - 40.1e^-0.031t2; r² = 0.85; RMSE = 9.2), and LM (Y = 363 - 33.0e^-0.018t2; r² = 0.99; RMSE = 1.4).
