Warm‐climate grasslands can be degraded by overgrazing and reduced soil fertility. However, legume trees integrated into these systems (silvopasture) provide long‐term marketable wood for sale add N to the system. In addition, tree legumes improve livestock diet providing high crude protein forage. Our research assessed biomass accumulation legumes: gliricidia [ Gliricidia sepium (Jacq.) Kunthe] sabia ( Mimosa caesalpiniifolia Benth.) grown in conventionally grazed signal grass Brachiaria...

Considerando a importância do uso da ensilagem como alternativa dos sistemas de alimentação animal, essa revisão objetiva apresentar resultados recentes disponíveis na literatura sobre alguns fatores que afetam o valor nutritivo silagem, notadamente forrageiras tropicais. A utilização silagem animal é uma prática importante sustentabilidade produtivos, considerando os custos com principalmente nos períodos seco ano. subprodutos indústria pode ser ferramenta para diminuir dependência insumos...

Ensiling warm-season grasses often requires wilting due to their high moisture content, and the presence of low-soluble sugars in these usually demands use additives during ensiling process. This study evaluated bromatological composition fodder silage from five Pennisetum sp. clones (IPA HV 241, IPA/UFRPE Taiwan A-146 2.114, 2.37, Elephant B, Mott). The contents 20 Polyvinyl chloride (PVC) silos, which were opened after 90 days storage, used for analysis evaluation pH, nitrogen, ammonia,...

Litter decomposition is an important pathway of nutrient return on grazed pastures and it may be affected by management practices. The objective this study was to evaluate the effects stocking rate (2, 3.9, 5.8 AU ha −1 ; 1 = 450 kg animal live weight) N fertilization level (0, 150, 300 yr ) signalgrass ( Brachiaria decumbens Stapf.) litter decomposition. Signalgrass placed in nylon bags incubated for 0, 4, 8, 16, 32, 64, 128, 256 d during 2009 2010. rates differed between years among...

Tree legumes are a viable option to increase ecosystem services provided by warm‐climate grasslands. Benefits of using tree in silvopasture systems (SPS) include the provision shade for livestock, biological N 2 fixation, and C sequestration. This study assessed cattle performance pasture characteristics signalgrass ( Brachiaria decumbens Stapf.) pastures monoculture or SPS. The following treatments were assessed: (i) signalgrass/sabiá Mimosa caesalpiniifolia Benth.), (ii)...

Rangelands and other native pastures occupy a large area of the planet, with greater temporal spatial botanical composition productivity variability. Despite continuous historical use these areas, including overgrazing fire exclusion, endemic legume species persist in some semiarid rangelands. The objective this work was to review current knowledge use, especially those Brazilian Caatinga rangeland. Studies that measure qualitative quantitative variations legumes are essential for ruminant...

ABSTRACT Low N availability is a major limitation in tropical and subtropical pasture systems one of the main causes for system degradation. Including legumes forage mixes may enhance soil‐N presence cycling, therefore mitigating problem. To test this theory, signal grass [ Brachiaria decumbens (Stapf) R. D. Webster] litter chemical composition decomposition after inclusion calopo ( Calopogonium mucunoides Desv.) at 0, 50, or 100% mass was evaluated. Litter samples were collected from both...
