The objective of this work was to evaluate three tropical forage species for their in vitro methane (CH4) production and organic matter degradability, in order to determine the relationships between forage grass nutritive quality and CH4 production. Guinea grass (Megathyrsus maximus), palisade grass (Urochloa brizantha), and signal grass (Urochloa decumbens) were evaluated. Palisade grass showed the highest organic matter, neutral detergent fiber, acid detergent fiber, lignin, and lower-crude protein content. Signal grass had the highest values for hemicellulose and neutral detergent fiber-nitrogen, and the lowest-cellulose content. Guinea grass and signal grass showed a higher-total gas production than palisade grass. Besides, Guinea grass showed an increased CH4 production, and palisade grass showed lower value for truly degraded organic matter, and reduced partitioning factor, in comparison to signal grass. An increased CH4 production was observed in cases of lower hemicellulose and paratitioning factor. The nutritive value and CH4 production of forages may be employed as parameters, aiming at the sustainability of ruminant production. |

The aim of this study was to evaluate the impact of pasture management practices on leaf canopy height (LCH) at 95% light interception (LI), since this is a valuable strategy of defoliation frequency. These relationships were investigated over two years with monocultures grown in a fully factorial block design crossing six C4 pasture grass species, two cutting intensities and two N levels. We found variations on LCH at 95% LI, mainly across seasons, but also between treatments. The range of these variations was species-dependent. Therefore, in order to maintain a target IL level, grassland managers should cut or graze at different heights according to the species and seasons. N fertilization and an increase in cutting height above ground level can provide a sward structure that allows lower pre-cutting/grazing height and, consequently, shorter intervals between defoliations. |
