To evaluate the pattern of defoliation in a Mombaça (Panicum maximum) grass pasture, experimental paddocks were grazed by Holstein heifers to maintain canopy height of: 60, 80, 100, 120 and 140 cm height. The experimental design was completely randomized, with two replications. The assessed sward structures were: canopy height; herbage and leaf lamina mass; canopy, sheath plus stems and leaves bulk density; tiller density and number and length of fully-expanded and emerging leaves. Linear decrease in plant defoliation probability (Y= […]
