Table 2 In vitro dry matter disappearance (IVDMD, mg/g DM) and ammonia-N accumulation (mmol/L) after 48-h in vitro ruminal fermentation of purple prairie clover (PPC; Dalea purpurea Vent.) and cool-season native grasses that were harvested when PPC reached the vegetative (VEG), full flower (FL) and seedpod (SP) stages and combined at different ratios
