1 CG = crabgrass; CWP = cowpea; LL = lablab; CG+CWP = crabgrass + cowpea; CG+LL = crabgrass + lablab; CG+CWP+LL = crabgrass + cowpea + lablab. 2 uNDF240 = undegraded neutral detergent fiber (after 240 h of fermentation). 3 pdNDF = potentially degradable neutral detergent fiber. 4 IVDMD = in vitro 30 h dry matter digestibility. 5 IVTDMD = in vitro 30 h true dry matter digestibility. Means with different superscripts in the same row differ (p < 0.05).
