Calculated IVDMD for the treatments soybean meal (SBM), canola meal (CAN), and sunflower meal (SUN). Dry matter degradation rates were not different (P > 0.05) across treatments. Degradation rates were calculated using the exponential equation of Ørskov and McDonald (1979): Y = a + b(1– e–ct), where Y = DM disappearance in time (t); a = DM disappearance at time 0; b = the proportion of DM disappearance during time, and c = the rate of DM disappearance of the degradable fraction.
