The objective of this study was to evaluate the Brachiaria brizantha cv. Marandu canopy structure maintained at different grazing heights under a continuous stocking rate and with a dietary supplementation strategy for the animals during the rainy season. This study also intended to observe the relationships of these variables with the grazing behaviors of the heifers. The effects of three canopy heights (15, 25 and 35 cm) were evaluated in association with three types of supplements: one mineral and two […]
Keywords: canopy height; grazing behavior; grazing time; herbage mass; number of meals

The experiment was performed in a natural pasture to evaluate the effect of the forage offer level on the pasture structure and ingestive behavior of steers. A completely randomized block design with four daily green forage offer levels (4, 8 12 and 16 kg GFDM/100 kg LW) and two replicates was used. The continuous grazing method with variable stocking rate was used. The increasing forage offer enhanced the higher strata frequency and determined higher inferior strata height. The increasing inferior […]
