• Resumen

  • This study aimed to evaluate the effect of burning on Crude Protein (CP), Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF) and Lignin in the dry matter of forages of interest in a field of rangelands, Pantanal. The study area had two treatments: without burning (control) and another area with burning, both areas ungrazed. Biomass aerial data was collected in both areas during eleven months after burning. In the first months after burning, when both areas were compared, there was a higher CP content of Andropogon bicornis and A. selloanus dry matter, which are rough and fibery species. There were no differences in the Axonopus purpusii and Mesosetum chaseae species, which are important forage species. Only lignin presented lower contents in dry matter after burning of Andropogon bicornis and Mesosetum chaseae. No differences were found in the other species.
