Performance of Beef Cattle Under Grazing as Affected by Urochloa decumbens Cultivars

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT Testing animal performance under grazing is fundamental to determine the potential of recently released, high‐yielding Urochloa decumbens hybrids. The objective was to evaluate the weight gain of young bulls grazing on pastures of U. decumbens cultivars Basilisk, BRS Carinás, and BRS Poraitê, as well as to assess the nutritive value and plant ...

Different Grazing Frequencies Modify the Structure, Production, and Nutritional Value of ‘Zuri’ Guineagrass in the Brazilian Cerrado

Grass and Forage Science, Volume 81, Issue 2, April-June 2026.
ABSTRACT The increasing climate variability in tropical regions demands management goals that allow for shorter rest periods without compromising pasture persistence. The objective of this study was to evaluate the effects of four pre‐grazing light interception (LI) levels on the structural, productive, and nutritional responses of ‘Zuri’ guinea grass ...

FITORREMEDIACIÓN DE UN SUELO CONTAMINADO CON PETRÓLEO EXTRA PESADO CON Megathyrsus maximus

Revista Internacional de Contaminación Ambiental, 2017
Soil contamination by petroleum is an environmental problem and phytoremediation has proved to be a promising method for treating such soils. However, selection of species for use in phytoremediation is a key factor for its successful application. The aim of this study was to investigate the phytoremediation potential of the grass Megathyrsus maximus
