Table 5 In situ ruminal degradation characteristics of dry matter (DM), neutral detergent fiber (aNDF), and crude protein (CP) disappearance of a 50:50 mixture of purple prairie clover (PPC; Dalea purpurea Vent.) and cool-season grasses. Both PPC and grass were harvested when PPC reached the vegetative (VEG), full flower (FL) and seedpod (SP) stages
