Abstract This 3‐year study evaluated the effects of grazing intensity on herbage and steer responses in continuously stocked Brachiaria brizantha cv. Marandu pasture Brazilian savanna. Treatments consisted three levels, characterized by canopy heights 15, 30 45 cm, measured twice per week. Responses variables included tiller population density (TPD), accumulation rate (HAR) body weight gain area (WGA). A decline TPD (1,237 vs. 767 tillers/m 2 ) was observed from first to third years, which...
Abstract In swards of tall, tufted, tropical grasses like Mombaça guinea grass ( Panicum maximum (Jacq.)), post‐grazing heights promote changes in sward structure, which influence animal performance. This study evaluated structure response to grazing management at two (30 and 50 cm), associated with 90 cm pre‐grazing height. Each treatment was allocated experimental unit (1.5 ha) three replicated blocks. Pastures were pre‐ estimate herbage mass, percentages leaf LP ), stem SP ) dead material...
Panicum maximum grasses are among the most used in Brazil because they have high forage production potential, nutritional value and adaptation to different climate conditions poor soils, which been improved by application of dolomitic limestone nitrogen fertilizers K2O, P2O5.

The objective of this study was to evaluate animal performance in Mombaça guineagrass (Panicum maximum Jacq.) pastures under intermittent grazing associated with two post-grazing heights (30 and 50 cm) a pre-grazing height 90 cm. A completely randomised block experimental design employed, treatments three replicates. were evaluated pre- grazing, determine the herbage mass, percentage leaf, stem dead material nutritive value. stocking rate (expressed unit, AU = 450 kg liveweight) adjusted...
Nitrogen fertilization has been recognized as an essential tool towards the establishment of sustainable intensification pasture-based livestock systems using tropical perennial grasses if, for a given ecosystem it is capable increasing forage growth, stocking rates and animal performance. This study assessed pasture growth traits, nutritive value, economic responses Panicum maximum cv. Mombaça guinea grass pastures subjected to different levels N (100 (N100), 200 (N200), 300 (N300) kg ha-1...
The objective of this work was to evaluate the sward structure and nutritive value Panicum maximum Jacq. cv. Tanzânia subjected rotational stocking managements characterised by a common pre-grazing condition 95% canopy light interception (LI) two post-grazing residues, 25 50 cm. Treatments (95/25, 95/50 - LI/residue) were assigned experimental units (groups six 2500 m² paddocks per treatment) according complete randomised block design, with replications. variables measured corresponded to:...
