Este estudo propõe utilizar a espectroscopia no infravermelho próximo (NIR) associada à regressão de mínimos quadrados parciais (PLS) como uma alternativa rápida, eficaz e não destrutiva para análise da composição da biomassa de capim-elefante. Modelos de calibração NIR-PLS foram desenvolvidos para avaliar os teores de glucana, xilana, arabinana, e...
O fruto do açaizeiro, espécie nativa da Amazônia, ganhou destaque no mundo em função de sua composição rica em antioxidantes. Entretanto, desde os tempos mais remotos, o açaí é considerado um alimento base para a população local, onde é encontrado em abundância. Desde populações rurais e ribeirinhas até os grandes centros urbanos da Amazônia, a pol...
The aim of this study was to evaluate the forage mass and accumulation and nutritional value of cultivars Kennedy and BRS Integra (Urochloa ruziziensis), subjected to two planting densities (15 and 30 plants/m2) and three stubble height (15, 30 and 40 cm). The experimental design was a randomized block, in a 2x2x3 factorial, with three replications...
Cratylia argentea is a leguminous shrub that has the potential for use as livestock feed in tropical areas. However, time-consuming and labor-intensive methods of chemical analysis limit the understanding of its nutritive value. Near-infrared spectroscopy (NIRS) is a low-cost technology widely used in forage crops to expedite chemical composition a...
This study aimed to evaluate fermentation losses and the fermentation profile of cactus pear silage with buffel grass predried. Five levels of inclusion of buffel grass pre-dried in cactus pear silage (0%; 15%; 25%; 35% and 45% on a dry matter basis) were evaluated with 6 replications, in a completely randomised design. After 90 storage days, silos...
Em 2020 o Brasil produziu 59,4 mil toneladas de feijão-mungo [Vigna radiata (L.) R. Wilczek] e apenas 5% desse total é consumido no País, principalmente na forma de brotos (moyashi). É originário da região Indo-Birmânia onde predomina a comercialização na forma de cotilédones, denominado de dal ou dahl. Avaliaram-se os teores de proteínas e de mine...
This study evaluated pasture productivity and nutritional characteristics of Urochloa decumbens in silvopastoral systems (SPS) with different eucalyptus cultivars and spatial arrangements providing differing levels of shade. SPS were arranged to provide 46 % shade (eucalyptus trees arranged in 2 double rows 2 m apart, with trees every 3 m in each r...
There is an increasing interest in essential oils extracted from Verbenaceae plant species as potential sources of biologically active compounds that could provide a starting point for designing novel phyto-pharmaceuticals in aquaculture. The present study was aimed to investigate the chemical composition, antioxidant activity, acute toxicity and a...

Ferralsols, which are estimated to cover 7.5 millions km² worldwide, are deeply weathered red or yellow soils found in the humid tropics. They are considered as the end of a geochemical sequence of weathering and are dominated by low-activity clay and sesquioxides. Their physical properties are closely related to their strong submillimetric granula...
