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

From: Effects of inclusion of purple prairie clover (Dalea purpurea Vent.) with native cool-season grasses on in vitro fermentation and in situ digestibility of mixed forages

^eSEM standard error of the means
^fL linear, Q quadratic, These are linear and quadratic contrasts across PPC percentages within PPC maturity
